To decide between these hypotheses, we need evidence that cannabis use preceded the psychosis; that plausible alternative explanations based on confounding can be excluded (Hall, 1987). The best evidence for answering these questions comes from longitudinal population-based studies that have assessed cannabis use before the onset of psychotic symptoms, followed the cohort over a substantial period and used statistical methods to assess the contribution of a variety of factors other than cannabis use that may explain the relationship (Macleod et al., 2004).
“The most common symptoms I treat with CBD are inflammatory conditions and it is also often used for pain,” Dr. Amin says. “Dosing is patient dependent. I always start low and go slowly. I have found that 15mg of CBD is a good starting dose for most patients. You have to be careful after that and titrate each patient individually due to the chance of potentially increasing anxiety and depressive symptoms. I have found the most convenient way for most of my patients to consume CBD is through tincture form. But capsules and edibles are also great ways to consume CBD on a daily basis.”

Cannabis was criminalized in various countries beginning in the 19th century. The British colonies of Mauritius banned cannabis in 1840 over concerns on its effect on Indian indentured workers;[206] the same occurred in British Singapore in 1870.[207] In the United States, the first restrictions on sale of cannabis came in 1906 (in District of Columbia).[208] It was outlawed in Jamaica (then a British colony) in 1913, in South Africa in 1922, and in the United Kingdom and New Zealand in the 1920s.[209] Canada criminalized cannabis in The Opium and Narcotic Drug Act, 1923,[210] before any reports of the use of the drug in Canada, but eventually legalized its consumption for recreational and medicinal purposes in 2018.[38]
In the United States, non-FDA approved CBD products are classified as Schedule I drugs under the Controlled Substances Act.[62] This means that production, distribution, and possession of non-FDA approved CBD products is illegal under federal law. In addition, in 2016 the Drug Enforcement Administration added "marijuana extracts" to the list of Schedule I drugs, which it defined as "an extract containing one or more cannabinoids that has been derived from any plant of the genus Cannabis, other than the separated resin (whether crude or purified) obtained from the plant."[63] Previously, CBD had simply been considered "marijuana", which is a Schedule I drug.[62][64]
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]

Although marijuana smoke contains a number of carcinogens findings from a limited number of well-designed studies do not suggest an increased risk for the development of either lung or upper airway cancer from light or moderate use. However, the evidence is mixed when it comes to the carcinogenic risks of heavy, long-term marijuana users, according to this study.
Indoor marijuana grows provide the most control over growing conditions. With a simple setup including a tent, proper lighting, and an air circulation system, home marijuana growers can produce consistent yields. Both soil and hydro systems can be utilized for indoor marijuana grows. Soil setups are generally cheaper and more forgiving, but hydro systems tend to be more common.
In 1924, Russian botanist D.E. Janichevsky concluded that ruderal Cannabis in central Russia is either a variety of C. sativa or a separate species, and proposed C. sativa L. var. ruderalis Janisch, and Cannabis ruderalis Janisch, as alternative names.[48] In 1929, renowned plant explorer Nikolai Vavilov assigned wild or feral populations of Cannabis in Afghanistan to C. indica Lam. var. kafiristanica Vav., and ruderal populations in Europe to C. sativa L. var. spontanea Vav.[53][62] In 1940, Russian botanists Serebriakova and Sizov proposed a complex classification in which they also recognized C. sativa and C. indica as separate species. Within C. sativa they recognized two subspecies: C. sativa L. subsp. culta Serebr. (consisting of cultivated plants), and C. sativa L. subsp. spontanea (Vav.) Serebr. (consisting of wild or feral plants). Serebriakova and Sizov split the two C. sativa subspecies into 13 varieties, including four distinct groups within subspecies culta. However, they did not divide C. indica into subspecies or varieties.[48][64]
I find it hilarious that there are trolls, even on product review pages. Anywho, I tried a bottle of their oil as a customer and not as an affiliate. I was suffering with a pretty rare condition and also had a severe iron deficiency. Both conditions resolved (I had had iron infusions months earlier that was taking its sweet time to make a difference with my symptoms), maybe a couple of months later. I also stoopped getting respiratory infections. I was able to get a lot more rest than I had been getting- eventually, the symptoms of my other conditions started disappearing. I have minimal symptoms now and I am working on keeping my diet nutrient-rich. I feel much better than I did before I started the oil. I haven’t used it again for financial reasons (I’m a sad cheapskate) but if I came into some money, I might buy another bottle.
^ Jump up to: a b This paper begins with a history of hemp use and then describes how hemp was constructed as a dangerous crop in the U.S. The paper then discusses the potential of hemp as an alternative crop. Luginbuhl, April M. (2001). "Industrial hemp (Cannabis sativa L): The geography of a controversial plant". The California Geographer (PDF). 41. California Geographical Society. pp. 1–14. Retrieved 2013-03-28. Hemp contains less than 1% THC, or tetrahydrocannabinols, the psychoactive property in marijuana. In other words, smoking hemp cannot create a 'high.' ... The dense growth of hemp eliminates other weeds.... The best growing technique for hemp, planting 300 to 500 plants per square meter, also helps authorities easily tell the hemp from marijuana, which is a plant that is less densely cultivated.

Scientific and clinical studies indicate that CBD could be effective in easing symptoms of a wide range of difficult-to-control conditions, including: rheumatoid arthritis, diabetes, alcoholism, PTSD, epilepsy, antibiotic-resistant infections and neurological disorders. CBD has demonstrated neuroprotective effects, and its anti-cancer potential is currently being explored at several academic research centers in the U.S. and other countries.

The dosage on the back label said to give him 1/2 to a full dropper twice a day due to his weight. I gave him 1/2 a dropper with his food. A few hours later I noticed he was wobbling when he walked and tripped up the stairs and collapsed. I took him to my vet and he said there must be THC in the oil. I thought, how can a company sell this product knowing full well that THC is extremely TOXIC for animals! The rep I bought the vials from said I gave him too much and to follow the dosage chart she gave me. Why would I give him anymore of this poison to my dog? Also, why did the product sold to me not have the proper dosage label? Also, I found that this product is Full Spectrum which means there is THC in the product.
Health, as defined by the World Health Organization (WHO), is "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."[1][2] This definition has been subject to controversy, as it may have limited value for implementation.[3][4][5] Health may be defined as the ability to adapt and manage physical, mental and social challenges throughout life.[6]
Short-term use increases both minor and major adverse effects.[104] Common side effects include dizziness, feeling tired, vomiting, and hallucinations.[104] Long-term effects of cannabis are not clear.[106] Concerns including memory and cognition problems, risk of addiction, schizophrenia in young people, and the risk of children taking it by accident.[103]
Industrial hemp is marketed a fiber, as a seed, or as a dual-purpose crop. Although detailed market information for hemp ins not readily available, estimates from Vote Hemp show that the total retail value of hemp products in the U.S. in 2017 was $820 million. This includes food and body products, clothing, auto parts, building materials, and other products.

The first example of the use of hempcrete was in 1986 in France with the renovation of the Maison de la Turquie in Nogent-sur-Seine by the innovator Charles Rasetti.[30] In the UK hemp lime was first used in 2000 for the construction of two test dwellings in Haverhill.[31] Designed by Modece Architects,[32] who pioneered hemp's use in UK construction, the hemp houses were monitored in comparison with other standard dwellings by BRE. Completed in 2009, the Renewable House is one of the most technologically advanced made from hemp-based materials.[33] The first US home made of hemp-based materials was completed in August 2010 in Asheville, North Carolina.[34]


Fig. 8. Scanning electron micrographs of the abaxial surface of a perigonal bract (which envelops the fruit). These bracts are the most intoxicating part of the plant, and may contain 20% THC, dry weight. The resin is synthesized both in stalked and sessile glands. Multicellular secretory glands (of phallic appearance), some broken stalks of these (note cellular appearance), and unicellular cystolith hairs (claw-like structures) are pictured. Fig. 9. Some important cannabinoids of cannabis resin. D9-THC (delta-9 tetrahydrocannabinol) is the chief intoxicant chemical and predominates in intoxicant strains, while the isomer D8-THC is usually present in no more than trace amounts. CBD (cannabidiol) is the chief non-intoxicant chemical, and predominates in non-intoxicant strains; it has sedative effects. The non-intoxicant CBN (cannabinol) is a frequent degradation or oxidation product. The non-intoxicant cannabichromene (CBC) is typically found in trace amounts in intoxicant strains. The non-intoxicant cannabigerol (CBG) is considered to be a precursor of the other cannbinoids (see Fig. 10).
Cannabis has been cultivated for millennia, but has been largely absent from scientific research during the past century. The herb is undergoing a resurgence of botanical and biomedical interest, spurred by claims of its therapeutic benefits. Yet research into these claims lags behind the legislation that allows medical marijuana use. Scientists are racing to fill this cannabis knowledge gap.
Earliest reference to euphoric use of C. sativa appears to date to China of 5 millennia ago, but it was in India over the last millennium that drug consumption became more firmly entrenched than anywhere else in the world. Not surprisingly, the most highly domesticated drug strains were selected in India. While C. sativa has been used as a euphoriant in India, the Near East, parts of Africa, and other Old World areas for thousands of years, such use simply did not develop in temperate countries where hemp was raised. The use of C. sativa as a recreational inebriant in sophisticated, largely urban settings is substantially a 20th century phenomenon.
While distributors have proclaimed HempWorx’s cannabis products as “legal in all 50 states,” and Josh Zwagil has said that it’s “100 percent legal” to ship them across state lines (more on this in the next section), the contract advises that distributors nevertheless “consult with an attorney regarding the extent of their personal legal liability with respect to their independent businesses,” noting that “laws differ according to jurisdiction.”
The CBD is often also the "city centre" or "downtown", but this is also often not the case. Midtown Manhattan is the largest central business district in New York City and in the world; yet Lower Manhattan, commonly called Downtown Manhattan, represents the second largest distinct CBD in New York City and is geographically situated south of Midtown. For example, London's "city centre" is usually regarded as encompassing the historic City of London and the mediaeval City of Westminster, whereas the City of London and the transformed Docklands area are regarded as its two CBDs. Mexico City also has a historic city centre, the colonial-era Centro Histórico, along with two CBDs: the mid-late 20th century Paseo de la Reforma - Polanco, and the new Santa Fe.
Another notable study conducted by Mechoulam was done on mice bred to have a version of type-1 diabetes. The diabetes was designed to manifest right around 14 weeks, so the mice were treated with CBD for the first 7 weeks of their life and then again in another 7 weeks. He concluded that only 30% had developed diabetes compared to the 90-100% given the placebo.
These mounting developments in the elicited a problem amongst cannabis cultivators across the US: decades of selectively breeding cannabis to achieve the maximum amount of THC for a strong high reduced the overall preponderance of CBD in cultivars across the country to trace lows. Essentially, CBD had been selectively bred out of existence across the country.
