Cannabis is used in three main forms: marijuana, hashish and hash oil. Marijuana is made from dried flowers and leaves of the cannabis plant. It is the least potent of all the cannabis products and is usually smoked or made into edible products like cookies or brownies (see Factsheet: Marijuana Edibles). Hashish is made from the resin (a secreted gum) of the cannabis plant. It is dried and pressed into small blocks and smoked. It can also be added to food and eaten. Hash oil, the most potent cannabis product, is a thick oil obtained from hashish. It is also smoked.
Put simply, “indica” strains are those associated with a strong body-high, feelings of sedation and relaxation. For this reason, indicas are often thought of as the “heavier” strains of cannabis, offering stronger highs that impact the whole body. They’re popular among marijuana users as pain relieving and sleep-inducing strains. Indicas are especially popular among medical cannabis patients.
Professors William Emboden, Loran Anderson, and Harvard botanist Richard E. Schultes and coworkers also conducted taxonomic studies of Cannabis in the 1970s, and concluded that stable morphological differences exist that support recognition of at least three species, C. sativa, C. indica, and C. ruderalis.[68][69][70][71] For Schultes, this was a reversal of his previous interpretation that Cannabis is monotypic, with only a single species.[72] According to Schultes' and Anderson's descriptions, C. sativa is tall and laxly branched with relatively narrow leaflets, C. indica is shorter, conical in shape, and has relatively wide leaflets, and C. ruderalis is short, branchless, and grows wild in Central Asia. This taxonomic interpretation was embraced by Cannabis aficionados who commonly distinguish narrow-leafed "sativa" strains from wide-leafed "indica" strains.[73]
Though there are some topical treatments, cannabis oil is typically administered orally to dogs. It also can be used in conjunction with traditional medications and treatments. Emerging research suggests there can be “synergistic benefits” between marijuana and traditional medications, Richter says. “There are few, if any, known significant drug interactions that you really need to be concerned about.”
I used it on my mother's feet (she's 90). She is great for testing anything because she's in an incredible amount of pain and absolutely NOTHING works for her. Two hours after I applied it, she came into my room and said, "I can't believe that cream actually worked. I still don't have any pain in my toes and the bottom of my feet. It worked so well, I forgot about the pain after you put it on..." Needless to say, she looks forward to an application every evening.
CBD interacts with receptors in the ECS indirectly and sustains various outcomes. For example, CBD can stop the body from absorbing anandamide, which is the compound that is associated with regulating pain. This is how CBD can reduce the amount of pain that a person feels, as well as inflammation – which is an underlying cause of various painful conditions.
Then came World War II. The Japanese attack on Pearl Harbor shut off foreign supplies of "manila hemp" fiber from the Philippines. The USDA produced a film called "Hemp For Victory" to encourage U.S. farmers to grow hemp for the war effort. The U.S. government formed the War Hemp Industries Department and subsidized hemp cultivation. During the war, U.S. farmers grew about a million acres of hemp across the Midwest as part of that program.
My grandma has advanced rheumatoid arthritis and osteoarthritis - debilitating pain and inflammation. She's on the 4th failed infusion. Nothing was working to control her pain and inflammation. I purchased the 1000mg mint CBD and the topical. I put the topical on her knees, ankles, shoulders, back, hips, and then gave her 15 1000mg drops. She instantly felt relief with the topical. She said it was a cooling pain relief. The topical smells really good.

CBD was first discovered in 1940 by Roger Adams, a prominent organic chemist at the University of Illinois. Shortly thereafter, other scientists began testing isolated cannabinoids on lab animals; notably, Walter S. Loewe ran trials on mice and rabbits with the cannabinoids THC, CBD and CBN. He found that CBD produced no observable effects in the animals’ behavior while THC caused, what he called, a “central excitant action” in rabbits. Despite science’s movement forward, scientists were completely unaware of the cannabinoids’ chemical structure, so no one could tell which specific compound resulted in which effect.
CBD is not toxic, not habit forming and not psychoactive.  Although CBD is derived from the hemp plant, it is not marijuana and does not get your pet “Stoned” or “Intoxicated”. CBD does not interfere or interact negatively with any of your pet’s ongoing medications or drugs. CBD possesses many healing properties and is safe to use. Elderly or aging pets benefit the most from the effects of CBD.
In the 1970s, the taxonomic classification of Cannabis took on added significance in North America. Laws prohibiting Cannabis in the United States and Canada specifically named products of C. sativa as prohibited materials. Enterprising attorneys for the defense in a few drug busts argued that the seized Cannabis material may not have been C. sativa, and was therefore not prohibited by law. Attorneys on both sides recruited botanists to provide expert testimony. Among those testifying for the prosecution was Dr. Ernest Small, while Dr. Richard E. Schultes and others testified for the defense. The botanists engaged in heated debate (outside of court), and both camps impugned the other's integrity.[57][58] The defense attorneys were not often successful in winning their case, because the intent of the law was clear.[65]
Every animal with a spinal column has an endocannabinoid system (ECS), which scientists estimate evolved more than 600 million years ago and has been carried forward across the millennia. This ancient system—discovered through the work of several researchers between roughly 1965 and 1995—is named for Cannabis sativa L., the plant species that most dramatically affects it. Its basic functions have been summarized as to “relax, eat, sleep, forget and protect.”
Cannabinoids, terpenoids, and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants.[42] As a drug it usually comes in the form of dried flower buds (marijuana), resin (hashish), or various extracts collectively known as hashish oil.[8] In the early 20th century, it became illegal in most of the world to cultivate or possess Cannabis for sale or personal use.
• Dr. Jamie Peyton, chief of small animal integrative medicine at University of California, Davis, Veterinary Medical Teaching Hospital, led a late 2017/early 2018 study on the current use of cannabis with companion animals. By anonymously filling out an online questionnaire, participants provided the study with data that can be used to inform future research (the study is now closed).

I’ve done a little research on the hemp and cannabis, and it looks to me like they’re both supposed to be medicine plants. From what I learned about the plants, they’ve been known to actually have multiple health benefits and even save lives of fourth stage cancer patients, sending the cancer into remission and therefore saving the patient lives. Banning this medicine plant has actually caused the deaths of many people who could have otherwise been saved by this plant. No wonder people are getting it other ways, I don’t blame them as long as it’s strictly for medical purposes. I even heard of a case where one child’s seizures were so bad they had to end up moving to Colorado as a last resort to save that little girl’s life by giving her cannabis because no other medicine worked for her.

And the products on the shelf aren't all the same, Ward said. "There can be many, many different varieties, and if you're thinking about doing this for medical reasons, you want to find a trusted source and do your research," she said. "Where does that oil come from, and how confident can you be that you know the exact percentages of the different cannabinoids in the product?"

Preliminary work in Germany (noted in Karus and Leson 1994) suggested that hemp could be grown on soils contaminated with heavy metals, while the fiber remained virtually free of the metals. Kozlowski et al. (1995) observed that hemp grew very well on copper-contaminated soil in Poland (although seeds absorbed high levels of copper). Baraniecki (1997) found similar results. Mölleken et al. (1997) studied effects of high concentration of salts of copper, chromium, and zinc on hemp, and demonstrated that some hemp cultivars have potential application to growth in contaminated soils. It would seem unwise to grow hemp as an oilseed on contaminated soils, but such a habitat might be suitable for a fiber or biomass crop. The possibility of using hemp for bioremediation deserves additional study.

• According to the documentary “The Union: The Business Behind Getting High” (available at YouTube), the first marijuana law in the United States was enacted in 1619, in Jamestown Colony, Virginia, and actually required farmers to grow hemp. Benjamin Franklin used hemp in his paper mill – one of the country’s first – and the first two copies of the Declaration of Independence were supposedly written on hemp paper.

This CBD pain relief cream includes a strong list of ingredients including eucalyptus, which is both anti-inflammatory as well as anti-bacterial, and Rosemary, an anti-oxidant and neural protectant. This is an excellent choice to try if you want to see if a CBD rub will help with your neuropathic pain from conditions such as fibromyalgia or sciatica.  


Starting a legal cannabis dispensary entails following strict laws and health and safety rules. The weed industry is a lot like food and beverages: to legally sell your products, you need strict supply chain management and have to be able to prove that you’re in compliance with all regulations. For that reason, the cannabis industry is redefining supply chain management.
By the 1930s, marijuana was banned in 24 states. The newly minted Federal Bureau of Narcotics launched a campaign against the drug, and newspapers fueled hysteria with headlines like the 1933 Los Angeles Examiner's "Murder Weed Found Up and Down the Coast — Deadly Marihuana Dope Plant Ready for Harvest That Means Enslavement of California Children." By 1937, Congress passed the Marihuana Tax Act, which effectively banned marijuana except for a few medicinal purposes, according to "Smoke Signals: A Social History of Marijuana – Medical, Recreational and Legal" (Scribner, 2012).
Hemp fibers are primarily used for textiles, paper, building materials, and other industrial products. Hurds, or shives, are short woody hemp fibers typically found inside the stalk. They’re used to make hempcrete, bedding materials, absorbents, particle board, ceiling panels, compost, and other industrial products. Bast fibers make up the outer portion of the stalk and are typically split into three categories — primary, or line fiber, secondary, and the tow. They are categorized according to their cell strength and cell wall thickness, which will determine the fiber’s strength, durability, and ultimately what the it can be used for.
In 2015, The Hebrew University of Israel published a study that documented the potency of single-molecule CBD extract versus the potency of whole-plant CBD-rich extract. It found that extract taken from whole plant CBD-rich cannabis is therapeutically superior to single-molecule extract. The scientists behind this study noticed that science had been utilizing pure, single-molecule CBD, which resulted in a bell-shaped dose-response curve. This means that CBD’s efficacy plummets at very high and very low doses.
He described an experiment that was done in Brazil in which a 200mg/day dosage of CBD was added to the anticonvulsants epilepsy patients were currently taking. Over the course of several months only 1 of the 7 patients showed no improvement; three became seizure-free; one experienced only one or two seizures, and two experienced reduced severity and occurrence of seizures.
When you think of most herbs, you probably think about taking them internally.  And, sure, that’s how we usually use plants these days.  But, in the past, a lot of herbal remedies actually included applying the plant to the outside of the skin.  And, that was the thought behind powerful CBD Cream.  Because, CBD comes from the famous herb cannabis – you’ve probably heard of it – and while taking cannabis internally has great benefits, that’s not the only way to get pain relief. 

The self-medication hypothesis was not supported in either the van Os or Henquet studies. Both studies found that early psychotic symptoms did not predict an increased risk of using cannabis (as is required by the self-medication hypothesis). The direction of the relationships was from early cannabis use to psychosis. Their negative results have recently been supported by Verdoux et al. (2002), who examined the temporal relationship between cannabis use and psychotic symptoms using an experience sampling method. They asked 79 college students to report on their drug use and experience of psychotic symptoms at randomly selected time points, several times each day over 7 consecutive days. The sample included high cannabis users (n = 41) and an over-representation of students identified as vulnerable to psychosis (n = 16). Verdoux and colleagues found that in time periods when cannabis was used, users reported more unusual perceptions, and these relationships were stronger in vulnerable individuals. There was no temporal relationship between reporting unusual experiences and using cannabis use, as would be predicted by the self-medication hypothesis.
• What's the dosing? This is a confusing one for many people. "A lot of brands don't do a good job of clearly instructing their consumer on the dosing," says Chris Roth, CEO and co-founder of Highline Wellness. When thinking about dosing, also consider whether your CBD is full-spectrum or isolate: Full-spectrum could include other cannabinoids like cannabidivarin or cannabigerol (this is important, since "there's something called the 'entourage effect' when all together, they're more effective than any one of them alone," Roth explains), while isolate is 100% CBD. "Some people might only need 10 milligrams of full-spectrum CBD, but with isolate, even taking 80 or 100 milligrams might not have the same effect," he says.
Hemp is not the same as marijuana. One really has nothing to do with the other. Hemp was made illegal back in the days when cotton was king in the south and southern cotton plantation owners did not want the competition. They lobbied for, and got a law against hemp being grown nationwide. It never had to do with drugs at that time, and still doesn’t. As always, money and government go hand in hand. Now, recently, South Carolina has legalized growing hemp again, which is the only state in 50 to do so. We will hope for more enlightened agri-business legislation across the nation, soon.
Also, you’ll notice in our “Pros” that we indicate that their products are indeed NON-GMO. Just FYI, the use of pesticides isn’t related to whether ingredients are GMO or non-GMO. GMOs (genetically modified organisms) are organisms created in a laboratory using genetic modification/engineering techniques. In the case of King Kanine, the hemp and other ingredients are naturally grown, not genetically modified.
Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain.[31] It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12.[12] Although currently classified as orphan receptors, these receptors are most closely related phylogenetically to the cannabinoid receptors.[12] In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist,[32] and this action may be involved in its antidepressant,[33][34] anxiolytic,[34][35] and neuroprotective effects.[36][37] It is an allosteric modulator of the μ- and δ-opioid receptors as well.[38] The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.[7]
Cement (Concrete) and Plaster. Utilizing the ancient technique of reinforcing clay with straw to produce reinforced bricks for constructing domiciles, plant fibers have found a number of comparable uses in modern times. Hemp fibers added to concrete increase tensile strength while reducing shrinkage and cracking. Whole houses have been made based on hemp fiber (Fig. 24, 25). In North America, such usage has only reached the level of a cottage industry. Fiber-reinforced cement boards and fiber-reinforced plaster are other occasionally produced experimental products. Hemp fibers are produced at much more cost than wood chips and straw from many other crops, so high-end applications requiring high strength seem most appropriate.
Due to almost a century of misinformation about Cannabis, the distinction between Cannabis and its two primary species — hemp and marijuana — has become unclear to the many and some even consider the three plants to be one in the same. Because of this, the three terms are often used interchangeably, which has created difficulties when understanding the usage and benefits of Hemp vs Marijuana and Cannabis in general.
Hemp is completely different from marijuana in its function, cultivation and application. But these differences didn’t stop our political leaders from getting confused and accidentally grouping all Cannabis species as a Schedule I Drug and banning it in 1970 under the Controlled Substances Act. Even after 45 years, the government still seems to have some confusion in distinguishing the two plants. Although legislation is being made, progress has been slow.In its application, hemp and marijuana serve completely different purposes. Marijuana, as it is widely known, is used for medicinal or recreational purposes. Hemp is used in variety of other applications that marijuana couldn’t possibly be used in. These include healthy dietary supplements, skin products, clothing, and accessories. Overall, hemp is known to have over 25,000 possible applications.

It is clear that there is a culture of idealistic believers in hemp in North America, and that there is great determination to establish the industry. As history has demonstrated, unbridled enthusiasm for largely untested new crops touted as gold mines sometimes leads to disaster. The attempt to raise silk in the US is probably the most egregious example. In 1826 a Congressional report that recommended the preparation of a practical manual on the industry resulted in a contagious desire to plant mulberries for silk production, with the eventual collapse of the industry, the loss of fortunes, and a legacy of “Mulberry Streets” in the US (Chapter 2, Bailey 1898). In the early 1980s in Minnesota, Jerusalem artichoke was touted as a fuel, a feed, a food, and a sugar crop. Unfortunately there was no market for the new “wonder crop” and hundreds of farmers lost about $20 million (Paarlberg 1990). The level of “hype” associated with industrial hemp is far more than has been observed before for other new crops (Pinfold Consulting 1998). Probably more so than any plant in living memory, hemp attracts people to attempt its cultivation without first acquiring a realistic appreciation of the possible pitfalls. American presidents George Washington and Thomas Jefferson encouraged the cultivation of hemp, but both lost money trying to grow it. Sadly in Canada in 1999 numerous farmers contracted to grow half of Canada’s crop area for hemp for the American-based Consolidated Growers and Processors, and with the collapse of the firm were left holding very large amounts of unmarketable grain and baled hemp straw. This has represented a most untimely setback for a fledgling industry, but at least has had a sobering effect on investing in hemp. In this section we emphasize why producers should exercise caution before getting into hemp.


Cannabis sativa, or marijuana, is frequently used for both recreation due to its psychoactive properties and medicinal use due to its effects on pain, nausea, and perhaps inflammation. Cannabis contains more than 60 cannabinoid compounds, with tetrahydrocannabinol (THC) being one of the main active components that act on CB1 and CB2 receptors in the body.267 New findings show that there are endogenous endocannabinoids that also act on these receptors and may play a role in limiting intestinal inflammation.268,269 Numerous basic and clinical studies have shown that cannabis use has positive effects on pain, specifically that originating within the GI tract, and inflammation.269-276 Cannabinoids have also been shown to prevent or ameliorate colitis in animal models.277-281
Cannabidiol has been shown to halt prions, the proteins that cause neurodegenerative diseases like Creutzfeldt-Jakob disease and mad cow. The formation and accumulation of prions were prevented with the aide of Cannabidiol during a study published in the Journal of Neuroscience in 2007. For mice that were infected, CBD increased their survival time by about a week.
This cream is nothing short of amazing. I bought it for my mother who suffers from fibromyalgia. She was skeptical about CBD. Always worrying what Aunt Pat or so and so would think. I also gave her a Chong's choice strawberry vape pen. She was toking on her new vape while I applied the cream to her legs. About 5 minutes later, mom was like ...valerie...I don't feel the pins and needles in my legs... I don't feel the creepy crawling feeling. I...I...I don't have any pain in my legs. How is that possible?! And I say to her...and do you feel high?... Nope she says. Only pain free. I then say to her... screw what Aunt Pat thinks. Mom agrees...screw aunt pat and all the others like her. Ignorance is a major burden on the CBD as well as the cannabis industry. If people would just take the time to understand and learn about the whole plant, the world would be a much better place. Anyway... yeah this stuff is pretty freaking awesome. Mom is already asking how she gets a refill.
As part of the Agriculture Improvement Act of 2018, or the 2018 Farm Bill, signed by Republican President Donald Trump, the Hemp Farming Act of 2018 removed hemp (with less than 0.3% THC) from Schedule I, the most restrictive classification of controlled substances that are considered highly prone to abuse and not to have any medicinal benefit. This move allowed for cultivation and distribution of hemp as a legal agricultural product. Under the Hemp Farming Act, hemp cultivation is no longer limited to state departments and universities. In addition, the act allows hemp farmers rights to water, crop insurance, and federal agricultural grants, as well as legal access to national banking. Hemp may also be transported across state lines.   

The use of Cannabis for seed oil (Fig. 36) began at least 3 millennia ago. Hempseed oil is a drying oil, formerly used in paints and varnishes and in the manufacture of soap. Present cultivation of oilseed hemp is not competitive with linseed for production of oil for manufacturing, or to sunflower and canola for edible vegetable oil. However, as noted below, there are remarkable dietary advantages to hempseed oil, which accordingly has good potential for penetrating the salad oil market, and for use in a very wide variety of food products. There is also good potential for hemp oil in cosmetics and skin-care products.
And whether or not you obtain a bank account for your cannabis dispensary, you’ll have to pay higher taxes than virtually any other industry. This is a result of federal Tax Code 280E. It prevents all plant-touching businesses -- companies that deal directly with the plant, rather than with accessories and ancillary services -- from deducting business expenses and using tax credits. Equipment, rent, insurance, advertising… cannabis dispensaries cannot deduct any of these expenses. This brings the average taxes paid by a weed business to around 70 percent.
The main psychoactive constituent of cannabis is tetrahydrocannabinol (THC) (Figure 9). There are numerous other cannabinoids found in smaller concentrations that may contribute to the medical problems associated with the use of marijuana. Hashish is the resinous secretion of the cannabis plant, which contains a high concentration of THC. It is dried, compressed, and smoked in pipes either singly or mixed with tobacco. Marijuana may be smoked as a cigarette (‘joint’) or orally ingested. Smoking has immediate effects whereas ingestion has been associated with unpredictable effects (Ohlsson et al. 1980). THC binds to a family of cannabinoid receptors in the cerebral cortex and interferes with the endogenous cannabinoid neurotransmitter system, causing cognitive, psychomotor, and pain modulatory effects (Calignano et al. 1998). There are physiologic dose-dependent effects on the CB1 receptors found in the pain processing areas of the brain and spinal cord. Heart rate is increased with variable effects on BP. Transient vasodilatation and hypotension may occur (Hillard 2000). These effects are not commonly seen even in severe overdose conditions. Chronic marijuana smokers rapidly develop tolerance to these vascular effects. There have been no reports of lethal marijuana intoxication. Chest pain may occur due to pneumothorax and pneumomediastinum caused by deep inhalations (Brody et al. 1988).
Cannabinoids, terpenoids, and other compounds are secreted by glandular trichomes that occur most abundantly on the floral calyxes and bracts of female plants.[42] As a drug it usually comes in the form of dried flower buds (marijuana), resin (hashish), or various extracts collectively known as hashish oil.[8] In the early 20th century, it became illegal in most of the world to cultivate or possess Cannabis for sale or personal use.

As more and more states legalize the use of marijuana, a product known as CBD oil has surged in popularity. A chemical compound found in the cannabis plant, CBD, or cannabidiol, is non-intoxicating and does not cause the noticeable euphoric effects associated with tetrahydrocannabinol (or THC, another marijuana compound). Products marketed as CBD oil may contain THC.
In 2016, the United States is the only industrialized country that does not allow hemp farming. Other countries and regions have incentivized their farmers and are now profiting from the harvest and development of hemp applications. China has a $200M hemp textile industry. Europe is utilizing hemp more for industrial purposes. Canada’s hemp industry has exploded in the past decade and its demand continues to grow at 20% per year – ironically, most of this demand comes from the US.

There is reasonable evidence from prospective epidemiological studies which suggests that cannabis use can precipitate schizophrenia in persons who are vulnerable because of a personal or family history of schizophrenia. There is also evidence that a genetic vulnerability to psychosis increases the risk that cannabis users will develop psychosis (McGuire et al., 1995; Arseneault et al., 2002; Verdoux et al., 2002). A casual relationship also has biological plausibility in that the cannabinoid and dopaminergic neurotransmitter systems interact in animals. D'Souza and colleagues (1999) have shown in a provocation study that THC produces a dose-dependent increase in psychotic symptoms under double-blind placebo conditions; and Caspi and colleagues (2005) have shown an interaction between specific alleles of the COMT allele and psychotogenic effects of cannabis. If these results can be replicated and extended, they will increase the likelihood that cannabis can be a contributory cause of psychosis in vulnerable individuals.
Marijuana or marihuana (herbal cannabis),[167] consists of the dried flowers and subtending leaves and stems of the female Cannabis plant.[168][169][170][171] This is the most widely consumed form,[171] containing 3% to 20% THC,[172] with reports of up-to 33% THC.[173] This is the stock material from which all other preparations are derived. Although herbal cannabis and industrial hemp derive from the same species and contain the psychoactive component (THC), they are distinct strains with unique biochemical compositions and uses. Hemp has lower concentrations of THC and higher concentrations of CBD, which decreases the psychoactive effects[174][175]
What is cannabis?Cannabis is a drug that comes from Indian hemp plants such as Cannabis sativa and Cannabis indica. The main active chemical in cannabis is THC (delta-9 tetrahydrocannabinol).Cannabis is a depressant drug. Depressant drugs do not necessarily make you feel depressed. Rather, they slow down the activity of the central nervous system and the messages going between the brain and the body. When large doses of cannabis are taken it may also produce hallucinogenic effects.For information on synthetic cannabinoids, see our "Legal high" facts page.Other namesCannabis is also known as grass, pot, hash, weed, reefer, dope, herb, mull, buddha, ganja, joint, stick, buckets, cones, skunk, hydro, yarndi, smoke and hooch.What does cannabis look like?Leaves from the cannabis plant are bright green and have a distinctive shape with five or seven leaflets. The flowering tops and upper leaves are covered in a sticky resin.Cannabis is used for the psychoactive (mind and mood-altering) effects of THC and other active ingredients. THC is the chemical in cannabis that makes you feel “high”.There are three main forms of psychoactive cannabis: marijuana, hashish and hash oil.Marijuana is the most common and least potent form of cannabis. Marijuana is the dried leaves and flowers of the plant.Hashish (“hash”) is dried cannabis resin, usually in the form of a small block. The concentration of THC in hashish is higher than in marijuana, producing stronger effects.Hash oil is a thick, oily liquid, golden brown to black in colour, which is extracted from cannabis. Hash oil is the strongest form of cannabis.How and why is it used?The different forms of cannabis are used in different ways:Marijuana is smoked in hand-rolled cigarettes (joints), or in a pipe (a bong).Hashish is usually added to tobacco and smoked, or baked and eaten in foods such as hash cookies.Hash oil is usually spread on the tip or paper of a cigarette and then smoked.Cannabis and hash can also be smoked in a vaporiser. Vaporisers heat cannabis to temperatures that release its active ingredients while minimising the toxins associated with burning.The THC in cannabis is absorbed into the bloodstream through the walls of the lungs (if smoked), or through the walls of the stomach and intestines (if eaten). The bloodstream carries the THC to the brain, producing the “high” effects. Drugs inhaled get into the bloodstream quicker than those eaten. This means that the effects of cannabis when smoked occur more rapidly than when eaten.Paper and textilesSome species of cannabis have few psychoactive effects. These plants are used to produce hemp fibre for use in paper, textiles and clothing.Medical usesCannabis has been used for medical purposes for many centuries. It has been reported that cannabis may be useful to help conditions such as:nausea and vomiting, particularly when associated with chemotherapywasting and severe weight loss, in people with HIV/AIDS, cancer, or anorexia nervosa, as it may be used as an appetite stimulantpain relief, for example in people with cancer and arthritisrelief from symptoms of some neurological disorders that involve muscle spasms, including multiple sclerosis and spinal cord injuryglaucomaepilepsyasthma.For more information, please click on the Australian Drug Foundation's DrugInfo Clearinghouse web site link below.
Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.
Cannabis played a large role in the Greco-Roman cultures as a source of both fiber, an intoxicant, and a medicine. Cannabis seeds were discovered in the ruins of Pompeii, and Greek rhetorician Athenaeus made note of hemp being used to make rope between 170 and 230 CE. Roman author and naturalist Pliny the Elder also made reference to a cannabis root decoction as a treatment for joint stiffness and gout in the first (1st) century BCE.
Consumers report using CBD for a huge variety of health and wellness reasons, but a lot more research is needed to determine which symptoms and ailments it works best for. Currently, there are more than 40 clinical trials enrolling patients to examine the effectiveness of CBD for a variety of diseases, including substance use disorder, chronic pain, post-traumatic stress disorder (PTSD), depression, schizophrenia, and many others. Most importantly, CBD is incredibly safe, and not addictive. Even young children can tolerate daily doses of up to twenty milligrams (20 mg) per kilogram (1 kg) of body weight (for a 175 pound adult, that’s more than 1,500 mg). The most common side effect of high-dose CBD is sleepiness.
There are many varieties of cannabis infusions owing to the variety of non-volatile solvents used.[189] The plant material is mixed with the solvent and then pressed and filtered to express the oils of the plant into the solvent. Examples of solvents used in this process are cocoa butter, dairy butter, cooking oil, glycerine, and skin moisturizers. Depending on the solvent, these may be used in cannabis foods or applied topically.[190]

Cannabis, also referred to as marijuana, has been an integral part of human civilizations for millennia. Both as a medicine and as a recreational substance, cannabis is the most popular illicit drug in the world. Today, the legal landscape that has prohibited marijuana for much of the twentieth century is giving way to decriminalization and full legalization. Legal, commercial cannabis businesses are already making an enormous economic impact.
So true. Hearst and Rockefeller did not want Hemp or any form of Cannabis interfering with their lucrative paper, pharmaceutical and oil industries. Hemp is versatile and renewable. It can be used for food, medicine, fuel, paper, clothing, plastic, building materials; just about anything paper and oil is used for. These bastard wealthy people have done a disservice to all people and for the sake of lining their already copiously rich pockets. They and those like them are criminals of the worst order

Despite advanced analytical techniques, much of the cannabis used recreationally is inaccurately classified. One laboratory at the University of British Columbia found that Jamaican Lamb's Bread, claimed to be 100% sativa, was in fact almost 100% indica (the opposite strain).[83] Legalization of cannabis in Canada (as of October 17, 2018) may help spur private-sector research, especially in terms of diversification of strains. It should also improve classification accuracy for cannabis used recreationally. Legalization coupled with Canadian government (Health Canada) oversight of production and labelling will likely result in more—and more accurate—testing to determine exact strains and content. Furthermore, the rise of craft cannabis growers in Canada should ensure quality, experimentation/research, and diversification of strains among private-sector producers.[84]
Oils are hot in the beauty world. As a beauty editor, I’ve slathered everything short of butter onto my face: argan, coconut, rosehip, sandalwood, chia, neroli, calendula, mandarin, macadamia, rice bran, seabuckthorn, patchouli, grapefruit seed, sesame seed, soybean, sweet almond, pomegranate seed, lemon myrtle, sunflower seed—even extra virgin olive oil from my pantry when I was desperate. I’ve washed my face with oil-based cleansers, and dabbed expensive mixtures being sold as “face oils” onto my skin in hopes of achieving that Instagram-ready glow. Contrary to popular belief, the right oil is actually good for your face and won’t clog your pores. Your skin needs a reasonable amount of oil to do its business; as a matter of fact, if you scrub away all your natural face oil (as I was prone to do with rubbing alcohol as a frustrated and misguided pizza-faced teen), you may actually be prone to more breakouts as your skin tries to make up for the imbalance. As cannabis meets up with the mainstream beauty world, cannabidiol (CBD) oil may be the next big thing.
Natural Doesn’t Mean Better: First of all, no marijuana or CBD product you might give your dog is natural. Apart from raw, unprocessed marijuana (which you should absolutely NOT give to your dog), anything you get has been processed or altered in some fashion. Second, natural things can be dangerous, too. For example, xylitol is a “natural” sugar-free sweetener, derived from sources like birch bark, but it is highly toxic to dogs.

There is clear evidence that recreational cannabis can produce a transient toxic psychosis in larger doses or in susceptible individuals, which is said to characteristically resolve within a week or so of absence (Johns 2001). Transient psychotic episodes as a component of acute intoxication are well-documented (Hall et al 1994)
