Cannabidiol has low affinity for the cannabinoid CB1 and CB2 receptors,[26][27] although it can act as an antagonist of CB1/CB2 agonists despite this low affinity.[27] Cannabidiol may be 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.[28] It also may act as an inverse agonist of GPR3, GPR6, and GPR12.[29] CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist.[30] It is an allosteric modulator of the μ- and δ-opioid receptors as well.[31] The pharmacological effects of CBD may involve PPARγ agonism and intracellular calcium release.[7]
Psychoactive – Any chemical substance that can enter the brain from the bloodstream and directly affect the central nervous system is considered psychoactive. Many psychoactive substances have medical applications (such as anesthetics, psychiatric drugs, etc.), but some of these substances are used solely for recreation, causing dangerous side effects and addiction.
In 2013 a CNN program that featured Charlotte's Web cannabis brought increased attention to the use of CBD in the treatment of seizure disorders.[78][79] Since then, 16 states have passed laws to allow the use of CBD products with a doctor's recommendation (instead of a prescription) for treatment of certain medical conditions.[80] This is in addition to the 30 states that have passed comprehensive medical cannabis laws, which allow for the use of cannabis products with no restrictions on THC content.[80] Of these 30 states, eight have legalized the use and sale of cannabis products without requirement for a doctor's recommendation.[80]
Parkinson’s disease. Some early research shows that taking cannabidiol daily for 4 weeks improves psychotic symptoms in people with Parkinson’s disease and psychosis. But taking a specific cannabis extract (Cannador) that contains THC and cannabidiol does not appear to improve involuntary muscle movements caused by the anti-Parkinson’s drug levodopa in people with Parkinson’s disease.
CBD Isolate is the purest supplement available. It’s a 99% pure CBD supplement derived from hemp oil. Despite its concentration, CBD isolate effects are similar to other CBD concentrates, and it can be used in a variety of ways. It can be consumed itself, added to foods and beverages, or vaporized. You can also add it to other CBD products to increase their potency.

Cannabis – A type of flowering plant that includes three distinct variations: Cannabis ruderalis, Cannabis indica, and Cannabis sativa. Cannabis has a wide range of industrial and medical applications. It has been used since antiquity for its sturdy fiber, for oils, and for medicinal purposes. However, it has also been used as a recreational drug, a fact that renders the cultivation of cannabis strictly regulated because of some variations including high concentrations of THC.
Vaping has grown in popularity with the rise of e-cigarettes, which were introduced to the mass market in the U.S. in 2007. Vaping devices include not just e-cigarettes, but also vape pens and advanced personal vaporizers (also known as ‘MODS’). E-cigarettes, which resemble smoked cigarettes, and vape pens, which resemble large fountain pens, are typically simpler in design and less expensive than devices that have been customized by the user.
^ Scott Gottlieb (July 30, 2019). "The CBD craze is getting out of hand. The FDA needs to act". The Washington Post. Retrieved July 31, 2019. ... many of the compound’s expansive benefits are fanciful, and in fact, the sale of much of the product is illegal under current law. The Food and Drug Administration must act to make sure commercial interests don’t strip away any legitimate value that the compound might have.
CBD (Cannabidiol) is a potent, non-psychoactive cannabinoid found in hemp oil. It is typically extracted from industrial hemp plants that are naturally high in CBD and other phytochemicals. It is the most prevalent of over 80 different cannabinoids found in natural hemp. It is commonly used for its therapeutic properties. Cannabidiol is responsible for a wide-range of positive health benefits through its interaction with the body's own endocannabinoid system.

Since industrial hemp is naturally rich in CBD and has been bred to have only trace amounts of THC, many people today are turning to industrial hemp products as an alternative to medical marijuana. Medical marijuana is not legal in all states in the US and many countries worldwide, while products made from industrial hemp can be a safe and legal alternative. You can get many of the same beneficial effects of medical marijuana from industrial hemp products without getting “high.”

Selective breeding of cannabis plants has expanded and diversified as commercial and therapeutic markets develop.[13] Some growers in the US succeeded in lowering the proportion of CBD-to-THC to accommodate customers who preferred varietals that were more mind-altering due to the higher THC and lower CBD content.[52] In the US, hemp is classified by the federal government as cannabis containing no more than 0.3% THC by dry weight. This classification was established in the 2018 Farm Bill and was refined to include hemp-sourced extracts, cannabinoids, and derivatives in the definition of hemp.[53]
As of April 2019, CBD extracted from marijuana remains a Schedule I Controlled Substance,[13][72][73][74] and is not approved as a prescription drug, dietary supplement, or allowed for interstate commerce in the United States. CBD derived from hemp (with 0.3% THC or lower) was delisted as a federally scheduled substance by the 2018 Farm Bill. FDA regulations still apply: hemp CBD is legal to sell as a cosmetics ingredient, but despite a common misconception, because it is an active ingredient in an FDA-approved drug, cannot be sold under federal law as an ingredient in food, dietary supplements, or animal food.[75] It is a common misconception that the legal ability to sell hemp (which may contain CBD) makes CBD legal.[75]
Preliminary research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses.[19] Safety studies of cannabidiol showed it is well-tolerated, but may cause tiredness, diarrhea, or changes in appetite as common adverse effects.[20] Epidiolex documentation lists sleepiness, insomnia and poor quality sleep, decreased appetite, diarrhea, and fatigue.[2]
The oral bioavailability of CBD is 13 to 19%, while its bioavailability via inhalation is 11 to 45% (mean 31%).[4][5] The elimination half-life of CBD is 18–32 hours.[6] Cannabidiol is metabolized in the liver as well as in the intestines by CYP2C19 and CYP3A4 enzymes, and UGT1A7, UGT1A9, and UGT2B7 isoforms.[2] CBD may have a wide margin in dosing.[17]
