In 1972, the Dutch government divided drugs into more- and less-dangerous categories, with cannabis being in the lesser category. Accordingly, possession of 30 grams or less was made a misdemeanor.[202] Cannabis has been available for recreational use in coffee shops since 1976.[203] Cannabis products are only sold openly in certain local "coffeeshops" and possession of up to 5 grams for personal use is decriminalised, however: the police may still confiscate it, which often happens in car checks near the border. Other types of sales and transportation are not permitted, although the general approach toward cannabis was lenient even before official decriminalisation.[204][205][206]
Hemp was made illegal to grow without a permit in the U.S. under the Controlled Substances Act passed in 1970 because of its relation to marijuana,[17] and any imported hemp products must meet a zero tolerance level.[87] Some states have made the cultivation of industrial hemp legal, but farmers in many states have not yet begun to grow it because of resistance from the federal Drug Enforcement Administration,[88] making "large-scale hemp growing" in the United States "not viable" as late as 2013.[89] In 2013, after the legalization of cannabis in the state, several farmers in Colorado planted and harvested several acres of hemp, bringing in the first hemp crop in the United States in over half a century.[90] Colorado,[91] Vermont, California, and North Dakota have passed laws enabling hemp licensure. All four states are waiting for permission to grow hemp from the DEA. Currently,[92] Oregon has licensed industrial hemp as of August 2009.[93] Congress included a provision in the Agricultural Act of 2014 that allowed colleges and state agencies to grow and conduct research on hemp in states where it is legal.[17] Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014.[94] Hemp production in North Carolina resumed in 2017,[95] and in Washington State the same year.[96] By the end of 2017, at least 34 U.S. states had industrial hemp programs.[97] In 2018, New York began taking strides in industrial hemp production, along with hemp research pilot programs at Cornell University, Binghamton University and SUNY Morrisville.[98]
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.[56][57] The defense attorneys were not often successful in winning their case, because the intent of the law was clear.[64]
Cannabis, also known as marijuana among other names,[n 1] is a psychoactive drug from the Cannabis plant used for medical or recreational purposes.[16][17][18] The main psychoactive part of cannabis is tetrahydrocannabinol (THC), one of 483 known compounds in the plant,[19] including at least 65 other cannabinoids.[20] Cannabis can be used by smoking, vaporizing, within food, or as an extract.[21]
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.
The cultivation of hemp in the EU is heavily weighted toward fiber production over oilseed production. In 1999, the EU produced about 27,000 t of hemp fiber, but only about 6,200 t of hemp seeds, mostly in France, and 90% of this was used as animal feed (Karus et al. 2000). The seeds (Fig. 33) have traditionally been employed as bird and poultry feed, but feeding the entire seeds to livestock has been considered to be a poor investment because of the high cost involved (although subsidization in Europe allows such usage, especially in France where hemp seeds are not legally permitted in human food). As pointed out later, higher yield and better harvesting practices may make whole hempseed an economical livestock feed. Moreover, seed cake left after expressing the oil is an excellent feed. Efforts are underway in Europe to add value in the form of processed products for hemp, especially cosmetics and food but, as noted below, the North American market is already quite advanced in oilseed applications.
A mixture of fiberglass, hemp fiber, kenaf, and flax has been used since 2002 to make composite panels for automobiles.[34] The choice of which bast fiber to use is primarily based on cost and availability. Various car makers are beginning to use hemp in their cars, including Audi, BMW, Ford, GM, Chrysler, Honda, Iveco, Lotus, Mercedes, Mitsubishi, Porsche, Saturn, Volkswagen[35] and Volvo. For example, the Lotus Eco Elise[36] and the Mercedes C-Class both contain hemp (up to 20 kg in each car in the case of the latter).[37]

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.

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.

Karl W. Hillig, a graduate student in the laboratory of long-time Cannabis researcher Paul G. Mahlberg[77] at Indiana University, conducted a systematic investigation of genetic, morphological, and chemotaxonomic variation among 157 Cannabis accessions of known geographic origin, including fiber, drug, and feral populations. In 2004, Hillig and Mahlberg published a chemotaxonomic analysis of cannabinoid variation in their Cannabis germplasm collection. They used gas chromatography to determine cannabinoid content and to infer allele frequencies of the gene that controls CBD and THC production within the studied populations, and concluded that the patterns of cannabinoid variation support recognition of C. sativa and C. indica as separate species, but not C. ruderalis.[52] The authors assigned fiber/seed landraces and feral populations from Europe, Central Asia, and Turkey to C. sativa. Narrow-leaflet and wide-leaflet drug accessions, southern and eastern Asian hemp accessions, and feral Himalayan populations were assigned to C. indica. In 2005, Hillig published a genetic analysis of the same set of accessions (this paper was the first in the series, but was delayed in publication), and proposed a three-species classification, recognizing C. sativa, C. indica, and (tentatively) C. ruderalis.[55] In his doctoral dissertation published the same year, Hillig stated that principal components analysis of phenotypic (morphological) traits failed to differentiate the putative species, but that canonical variates analysis resulted in a high degree of discrimination of the putative species and infraspecific taxa.[78] Another paper in the series on chemotaxonomic variation in the terpenoid content of the essential oil of Cannabis revealed that several wide-leaflet drug strains in the collection had relatively high levels of certain sesquiterpene alcohols, including guaiol and isomers of eudesmol, that set them apart from the other putative taxa.[79] Hillig concluded that the patterns of genetic, morphological, and chemotaxonomic variation support recognition of C. sativa and C. indica as separate species. He also concluded there is little support to treat C. ruderalis as a separate species from C. sativa at this time, but more research on wild and weedy populations is needed because they were underrepresented in their collection.
A limited number of studies have examined the effects of cannabis smoking on the respiratory system.[85] Chronic heavy marijuana smoking is associated with coughing, production of sputum, wheezing, and other symptoms of chronic bronchitis.[68] The available evidence does not support a causal relationship between cannabis use and chronic obstructive pulmonary disease.[86] Short-term use of cannabis is associated with bronchodilation.[87]
There are many ways to prepare cannabis for consumption. And while final marijuana products may come in many forms, each aims to provide rich concentrations of the terpenes, cannabinoids, and other desirable compounds the marijuana plant produces. From the simple process of drying and curing marijuana flowers, to the sophisticated chemistry of producing cannabis concentrates, here’s a guide to the most common forms of cannabis.

But all was not well. Harper has continued to experience health issues related to her condition. And seven months after starting to use CBD oil, Harper’s seizures returned— although not as frequently as before. Penny uses eleven iPhone reminders to keep track of Harper’s daily regimen of medications and food, and she records all of Harper’s seizures in a thickly bound black book. But as her parents continue to closely monitor Harper’s health and adjust her medications accordingly, her doctors are tightly limited in the advice they can offer when it comes to CBD oil. “There’s no research on this product, so they don’t say it’s good or bad. They just say, ‘Don’t stop giving it,’” Penny told me.

A 2016 review of animal studies indicated that cannabidiol has potential as an anxiolytic for relief of anxiety-related disorders and fear.[11] Reviews of preliminary research showed cannabidiol has potential for improving addictive disorders and drug dependence, although as of 2016, they indicated limited high-quality evidence for anti-addictive effects in people.[88][89][90]
Tammy et al, Through trial and error you will find a correct dosage. Try 50 mg daily....25 each 2x daily....if no results up the dosage until it works for you. Remember, there has never been a death from marijuana or CBD use. You might want to try a tincture or rub with CBD and THC. You won't get the psych high from it. Helps my friend with PArkinsons tremors. She takes 50mg of tincture and uses the rub morning and night. It is a miracle for arthritis. Good luck
Hemp is a bast fiber crop, i.e. the most desirable (“long”) fibers are found in the phloem-associated tissues external to the phloem, just under the “bark.” The traditional and still major first step in fiber extraction is to ret (“rot”) away the softer parts of the plant, by exposing the cut stems to microbial decay in the field (“dew retting,” shown in Figs. 46 and 47) or submerged in water (“water retting, ” shown in Fig. 13). The result is to slough off the outer parts of the stem and to loosen the inner woody core (the “hurds”) from the phloem fibers (Fig. 14). Water retting has been largely abandoned in countries where labor is expensive or environmental regulations exist. Water retting, typically by soaking the stalks in ditches, can lead to a high level of pollution. Most hemp fiber used in textiles today is water retted in China and Hungary. Retting in tanks rather than in open bodies of water is a way of controlling the effluents while taking advantage of the high-quality fiber that is produced. Unlike flax, hemp long fiber requires water retting for preparation of high-quality spinnable fibers for production of fine textiles. Improved microorganisms or enzymes could augment or replace traditional water retting. Steam explosion is another potential technology that has been experimentally applied to hemp (Garcia-Jaldon et al. 1998). Decorticated material (i.e. separated at least into crude fiber) is the raw material, and this is subjected to steam under pressure and increased temperature which “explodes” (separates) the fibers so that one has a more refined (thinner) hemp fiber that currently is only available from water retting. Even when one has suitably separated long fiber, specialized harvesting, processing, spinning and weaving equipment are required for preparing fine hemp textiles. The refinement of equipment and new technologies are viewed as offering the possibility of making fine textile production practical in western Europe and North America, but at present China controls this market, and probably will remain dominant for the foreseeable future.
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.
Retting is generally done in the field (Fig. 46, 47). This typically requires weeks. The windrows should be turned once or twice. If not turned, the stems close to the ground will remain green while the top ones are retted and turn brown. When the stalks have become sufficiently retted requires experience—the fibers should have turned golden or grayish in color, and should separate easily from the interior wood. Baling can be done with any kind of baler (Fig. 48). Stalks should have less than 15% moisture when baled, and should be allowed to dry to about 10% in storage. Bales must be stored indoors. Retted stalks are loosely held together, and for highest quality fiber applications need to be decorticated, scutched, hackled, and combed to remove the remaining pieces of stalks, broken fibers, and extraneous material. The equipment for this is rare in North America, and consequently use of domestically-produced fiber for high quality textile applications is extremely limited. However, as described above relatively crude fiber preparations also have applications.

Henry Ford recognized the utility of hemp in early times. In advance of today’s automobile manufacturers, he constructed a car with certain components made of resin stiffened with hemp fiber (Fig. 19). Rather ironically in view of today’s parallel situation, Henry Ford’s hemp innovations in the 1920s occurred at a time of crisis for American farms, later to intensify with the depression. The need to produce new industrial markets for farm products led to a broad movement for scientific research in agriculture that came to be labeled “Farm Chemurgy,” that today is embodied in chemical applications of crop constituents.
The exploding recreational market for marijuana has rapidly popularized many methods of consuming cannabis that was decidedly part of the fringe just a few short years ago. Smoking marijuana remains the most widely embraced method, due to the greater accessibility of marijuana flower. But legal recreational cannabis is introducing many marijuana users to new forms of the drug, especially concentrates and edibles. Here’s a brief overview of the major methods for consuming marijuana.

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).[82] 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.[83]

We gave the highest points to companies that use a CBD distillate for their tinctures. The process of distillation creates an extract that is pure on a molecular level. There are people who think distillate is too pure, and that a full spectrum decarb produces a more effective tincture. But in light of the inconclusive evidence, we prefer a distillate. The process allows for a high degree of control as to the finished product. It’s also odorless and tasteless, so those tinctures tend to taste better.
Some manufacturers ship CBD products nationally, an illegal action which the FDA has not enforced in 2018, with CBD remaining as the subject of an FDA investigational new drug evaluation and is not considered legal as a dietary supplement or food ingredient as of November 2018.[71] CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.[72][73]

Industrial hemp is from the plant species Cannabis sativa and has been used worldwide to produce a variety of industrial and consumer products. Hemp is a source of fiber and oilseed grown in more than 30 nations. In the United States production is controlled under drug enforcement laws. To produce industrial hemp in the United States the grower must obtain a permit from the Drug Enforcement Agency (DEA).
Finally, the entire marijuana flower structure is coated with resinous crystals called trichomes. Trichomes are translucent, mushroom-like glands that form on the entire flowering structure and even the stems of the marijuana plant. These bulb-shaped glands secrete the rich, aromatic essential oils that give cannabis its smells and flavors. Trichomes also contain cannabinoids.
Industrial hemp may be grown in Montana only by the Montana Department of Agriculture (MDA) through the Industrial Hemp Pilot Program or by institutions of higher education in Montana for agricultural or academic research. Only seed purchased from the Pilot Program seed repository or ordered from a DEA-approved source can legally be planted in Montana. Industrial hemp is currently regulated as a Schedule I Controlled Substance by the federal government. Persons who violate state or federal laws regarding hemp may be subject to federal prosecution under the Controlled Substances Act (CSA). Refer to the DEA website for more information.
In the UK, the Department for Environment, Food and Rural Affairs treats hemp as a purely non-food crop, but with proper licensing and proof of less than 0.2% THC concentration, hemp seeds can be imported for sowing or for sale as a food or food ingredient.[18] In the U.S., imported hemp can be used legally in food products and, as of 2000, was typically sold in health food stores or through mail order.[16]
