While research into the effects of CBD on specific conditions is important, a broader perspective on the relationship between CBD and the human body is necessary to understand how this unique compound works. Interestingly, many of the conditions that are supposedly helped by CBD have no well-understood cause, from acne to Alzheimer’s disease. However, one of the few common denominators between these conditions is the involvement of the endocannabinoid system (ECS) in their causes.

Over the ages, countless innovations have attempted to improve on the basic experience of inhaling the smoke of combusted cannabis. As a result, there are numerous ways to smoke marijuana. The rolling technique is at the root of joints, blunts, and spliffs. On the other hand, glassware and other devices are essential for smoking weed out of a pipe, bong, or bubbler.


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.
The psychoactive effects of cannabis are known to have a triphasic nature. Primary psychoactive effects include a state of relaxation, and to a lesser degree, euphoria from its main psychoactive compound, tetrahydrocannabinol. Secondary psychoactive effects, such as a facility for philosophical thinking, introspection and metacognition have been reported among cases of anxiety and paranoia.[94] Finally, the tertiary psychoactive effects of the drug cannabis, can include an increase in heart rate and hunger, believed to be caused by 11-OH-THC, a psychoactive metabolite of THC produced in the liver.
μ-Opioid receptor agonists (opioids) (e.g., morphine, heroin, hydrocodone, oxycodone, opium, kratom) α2δ subunit-containing voltage-dependent calcium channels blockers (gabapentinoids) (e.g., gabapentin, pregabalin, phenibut) AMPA receptor antagonists (e.g., perampanel) CB1 receptor agonists (cannabinoids) (e.g., THC, cannabis) Dopamine receptor agonists (e.g., levodopa) Dopamine releasing agents (e.g., amphetamine, methamphetamine, MDMA, mephedrone) Dopamine reuptake inhibitors (e.g., cocaine, methylphenidate) GABAA receptor positive allosteric modulators (e.g., barbiturates, benzodiazepines, carbamates, ethanol (alcohol) (alcoholic drink), inhalants, nonbenzodiazepines, quinazolinones) GHB (sodium oxybate) and analogues Glucocorticoids (corticosteroids) (e.g., dexamethasone, prednisone) nACh receptor agonists (e.g., nicotine, tobacco, arecoline, areca nut) Nitric oxide prodrugs (e.g., alkyl nitrites (poppers)) NMDA receptor antagonists (e.g., DXM, ketamine, methoxetamine, nitrous oxide, phencyclidine, inhalants) Orexin receptor antagonists (e.g., suvorexant)

We’ve systematically sought out quality hemp cultivars for our CBD oil ingredients. We always test for purity and potency with third-party laboratories because safety is paramount to Bluebird. Hemp, because of its innate ability to thrive easily, doesn’t require pesticides (the aromatic terpene compounds in hemp can actually act as natural pesticides), fertilizers, or herbicides in its cultivation, and requires much less water than standard commercial farming. All of our hemp is grown and processed in the USA using organic methods.
Hempworx boasts in this YouTube video that they pay huge commissions (up to 85% of revenue) to their affiliates. That means that up to 85% of the price that people pay is being paid in commissions to the selling affiliate and their “upline” network of other Hempworx affiliates. The video also promises the potential for affiliates to earn iPads, flatscreen TVs, luxury vacations, cruises, diamond watches, $100,000 cash bonuses and even new cars.
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]
NATURE By Elie Dolgin The feat, described on 27 February in Nature, turns a sugar in brewer’s yeast (Saccharomyces cerevisiae) called galactose into tetrahydrocannabinol (THC), the main psychoactive compound in cannabis (Cannabis sativa). The altered yeast can also produce cannabidiol (CBD), another major cannabinoid that’s attracted attention lately for its …
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,[18] and any imported hemp products must meet a zero tolerance level.[92] 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,[93] making "large-scale hemp growing" in the United States "not viable" as late as 2013.[94] 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.[95] Colorado,[96] 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,[97] Oregon has licensed industrial hemp as of August 2009.[98] 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.[18] Hemp production in Kentucky, formerly the United States' leading producer, resumed in 2014.[99] Hemp production in North Carolina resumed in 2017,[100] and in Washington State the same year.[101] By the end of 2017, at least 34 U.S. states had industrial hemp programs.[102] 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.[103]
In the 1950s, the Narcotics Control Act and the Boggs Act stiffened penalties for marijuana possession, with first-time offenses requiring two to 10 year sentences and a minimum $20,000 fine, according to PBS.org. Penalties were relaxed in the 1970s, but President Ronald Reagan increased federal penalties for marijuana possession in the 1980s. On the federal level, marijuana is now regulated under the Controlled Substances Act as a schedule 1 drug, meaning the government considers it to have a high potential for abuse with no legitimate medical or therapeutic uses.

Zammit and colleagues (2002) reported a 27-year follow-up of the Swedish cohort study. This study improved on the earlier study in the following ways: the psychiatric register provided more complete coverage of cases diagnosed with schizophrenia; and there was better statistical control of more potentially confounding variables, including other drug use, IQ, known risk factors for schizophrenia and social integration. Cannabis use at baseline predicted a dose–response relationship between the frequency of cannabis use at age 18 and the risk of schizophrenia during the follow-up. The relationship persisted after statistically controlling for the effects of other drug use and other potential confounding factors, including a history of psychiatric symptoms at baseline. They estimated that 13 percent of cases of schizophrenia could be averted if all cannabis use were prevented.
Several animal studies have led researchers to believe that cannabis could reverse signs of aging in the brain. Aging mice treated with small daily doses of THC showed a reversal in cognitive decline. However, past studies on the effects of cannabis on human memory show less promising results. Still, with few viable treatments for dementia, medical marijuana is receiving increased attention in this area.

For profitable hemp farming, particularly deep, humus-rich, nutrient-rich soil with controlled water flow is preferable. Waterlogged acidic, compressed or extremely light (sandy) soils primarily affect the early development of plants.[citation needed] Steep and high altitudes of more than 400 m above sea level are best avoided. Hemp is relatively insensitive to cold temperatures and can withstand frost down to −5 °C.[citation needed] Seeds can germinate down to 1–3 °C.[citation needed] Hemp needs a lot of heat, so earlier varieties come to maturation. The water requirement is 300–500 l/kg dry matter.[citation needed] This is around 1/14th that of cotton, which takes between 7,000 and 29,000 l/kg, according to WWF.[citation needed] Roots can grow up to 3 feet into the soil and use water from deeper soil layers. 

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.
“Cannatonic” is one known popular CBD-rich strain which is known to contain 6.5% CBD by weight, and the same amount of THC, making for one of the most medicinal strains out there. Sour Tsunami, Ghost Rider, Harlequin, Jamaican Lion and Omrita Rx3 have been tested several times by several labs as high as 18% CBD with equal or lower percentages of THC (3:2 ratio of CBD to THC in most cases).
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.
Hemp seeds have an attractive nutty taste, and are now incorporated into many food preparations (Fig. 34), often mimicking familiar foods. Those sold in North America include nutritional (granola-type) or snack bars, “nut butters” and other spreads, bread, pretzels, cookies, yogurts, pancakes, porridge, fruit crumble, frozen dessert (“ice cream”), pasta, burgers, pizza, salt substitute, salad dressings, mayonnaise, “cheese,” and beverages (“milk,” “lemonade,” “beer,” “wine,” “coffee nog”). Hemp seed is often found canned or vacuum-packed (Fig. 35). Alcoholic beverages made with hemp utilize hempseed as a flavorant. Hemp food products currently have a niche market, based particularly on natural food and specialty food outlets.
Do not use cannabis if you are pregnant or could become pregnant. There is some evidence that women who smoke cannabis during the time of conception or while pregnant may increase the risk of their child being born with birth defects. Pregnant women who continue to smoke cannabis are probably at greater risk of giving birth to low birthweight babies.
A topical rub whose proven ingredients are quickly absorbed through the skin to help melt away tension, muscle aches, joint pains, and symptoms related to rheumatoid arthritis. In fact, HempWorx advertises that CBD products (not Relief Icy Rub, specifically) have been shown to help relieve pain more effectively than opioid painkillers in some instances:
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
Millennia of selective breeding have resulted in varieties that display a wide range of traits; e.g. suited for a particular environments/latitudes, producing different ratios and compositions of terpenoids and cannabinoids (CBD, THC, CBG, CBC, CBN...etc.), fibre quality, oil/seed yield, etc. Hemp grown for fiber is planted closely, resulting in tall, slender plants with long fibers.[citation needed]
Not true. A family member of mine also failed a drug test using Hempworx that was supposedly zero THC. They contacted their rep who refused to respond to calls or texts. So then they went straight to the company who said they were sorry but nothing they could do because supposedly their lab is different than the one that did the drug test??? What a scam. 

Hemp extract is taken from the whole plant and contains higher levels of CBD than hemp seed oil.  This is where the CBD levels come from.  However, we are confused by the labeling.  If we expect the 500 product to have 500 mg of CBD, are we right?  The label shows 500 mg of ‘phytocannabinoid hemp oil’.  The solution is that about 160% of that is CBD, with the other cannabinoids as a tag along.  This is effective.
To make matters more confusing, nine states (including California, Washington, and Colorado) let residents buy cannabis-based products with or without THC. Nearly two dozen other “medical marijuana states” allow the sale of cannabis, including capsules, tinctures, and other items containing CBD or THC, at licensed dispensaries to people whose doctors have certified that they have an approved condition (the list varies by state but includes chronic pain, PTSD, cancer, autism, Crohn’s disease, and multiple sclerosis). Sixteen more states legalized CBD for certain diseases. But because all these products are illegal according to the federal government, cannabis advocates are cautious. “By and large, the federal government is looking the other way,” says Paul Armentano, deputy director of the Washington, DC–based National Organization for the Reform of Marijuana Laws (NORML), but until federal laws are changed, “this administration or a future one could crack down on people who produce, manufacture, or use CBD, and the law would be on its side.”
The environment is often cited as an important factor influencing the health status of individuals. This includes characteristics of the natural environment, the built environment and the social environment. Factors such as clean water and air, adequate housing, and safe communities and roads all have been found to contribute to good health, especially to the health of infants and children.[18][29] Some studies have shown that a lack of neighborhood recreational spaces including natural environment leads to lower levels of personal satisfaction and higher levels of obesity, linked to lower overall health and well being.[30] This suggests that the positive health benefits of natural space in urban neighborhoods should be taken into account in public policy and land use.
Hempworx probably has some utility as a multi-level marketing tool.  If we believe the lab reports, the CBD oil may be a good product.  It has at least 10 mg of CBD per dropper, and less than 1 mg of other cannabinoids.  Even the coffee tells you exactly how much CBD is in it and it is a therapeutic amount.  So, they get a good grade for this.  This is a good mix of cannabinoids.  However, it comes at the expense of an affiliate program so the price is significantly marked up.
The vegetable oils have been classified by “iodine value” as drying (120–200), semi-drying (100–120), and non-drying (80–100), which is determined by the degree of saturation of the fatty acids present (Raie et al. 1995). Good coating materials prepared from vegetable oil depend on the nature and number of double bonds present in the fatty acids. Linseed oil, a drying oil, has a very high percentage of linolenic acid. Hempseed oil has been classified as a semi-drying oil, like soybean oil, and is therefore more suited to edible than industrial oil purposes. Nevertheless hemp oil has found applications in the past in paints, varnishes, sealants, lubricants for machinery, and printing inks. However, such industrial end uses are not presently feasible as the oil is considered too expensive (de Guzman 2001). Larger production volumes and lower prices may be possible, in which case hemp oil may find industrial uses similar to those of linseed (flax), soybean, and sunflower oils, which are presently used in paints, inks, solvents, binders, and in polymer plastics. Hemp shows a remarkable range of variation in oil constituents, and selection for oilseed cultivars with high content of valued industrial constituents is in progress.

Cannabis lowers the pressure in the eye that causes optic nerve damage leading to glaucoma. Research has shown conclusively that marijuana users experience lower internal eye pressure while the body metabolizes THC. However, the psychoactive side effects of using THC to treat glaucoma make cannabis a nonviable medication for most people with the disease. 

The scientific debate regarding taxonomy has had little effect on the terminology in widespread use among cultivators and users of drug-type Cannabis. Cannabis aficionados recognize three distinct types based on such factors as morphology, native range, aroma, and subjective psychoactive characteristics. Sativa is the most widespread variety, which is usually tall, laxly branched, and found in warm lowland regions. Indica designates shorter, bushier plants adapted to cooler climates and highland environments. Ruderalis is the informal name for the short plants that grow wild in Europe and Central Asia.

The confusion between industrial hemp and marijuana is based on the visual similarities of widely differentiated varieties of plants. By definition, industrial hemp is high in fiber and low in active tetrahydrocannabinol (THC), the psychoactive ingredient in marijuana that makes some cannabis varieties a valued drug. Canada and the European Union maintain this distinction by strictly regulating the THC levels of industrial hemp, requiring it to be less than 0.3 percent, compared to THC levels of between 3 to 30 percent in marijuana.

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.
You see, I experienced my first “episode” at 31. I was standing over the sink one fall morning and sneezed. Hard. Before I knew it, my lower back gave way. Then a tremendous pain engulfed my body. And get this: The episodes recurred whenever they felt like it—peskier than a hungry mosquito. Twice a year if I was lucky, more if I wasn’t. (Once, in Paris, I actually had to purchase a cane. The only consolation to that otherwise crippling experience was that it felt comically chic: I was hobbling in The City of Light, clad in Hermès scarves.)

• 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.
^ 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.

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.

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.
