The two main receptors in the endocannabinoid system are CB1 and CB2. Where THC directly affects these receptors, CBD has a subtler, more indirect approach. Instead of attaching to these receptors, CBD affects how these receptors signal the body and its chemicals. Furthermore, CBD increases the production of the body’s own cannabinoids by blocking the enzymes that can break them down.

While marijuana is bred with the only purpose of maximizing its THC concentration, industrial hemp always has trace amounts of THC and naturally occurring high amounts of CBD (it has the highest CBD/THC ratio of all cannabis strains, even Cannabis ruderalis) This means that industrial hemp’s chemical profile makes it incapable of inducing intoxicating effects and getting you “high” from ingesting it.
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]

Cannabidiol is insoluble in water but soluble in organic solvents such as pentane. At room temperature, it is a colorless crystalline solid.[34] In strongly basic media and the presence of air, it is oxidized to a quinone.[35] Under acidic conditions it cyclizes to THC,[36] which also occurs during pyrolysis (smoking).[37] The synthesis of cannabidiol has been accomplished by several research groups.[38][39][40]
In the United States, the cannabidiol drug Epidiolex was approved by the Food and Drug Administration in 2018 for treatment of two epilepsy disorders.[12] The side effects of long-term use of the drug include somnolence, decreased appetite, diarrhea, fatigue, malaise, weakness, and sleeping problems.[2] As of mid-2019 in the United States, CBD is a Schedule I controlled substance that is illegal for use in human foods, dietary supplements, other consumer products, or pet foods.[13][14]

Based on what we’ve seen above, we can answer the question by saying that CBD and THC are so different that it’s difficult to compare them directly. But while THC can be abused as a drug, CBD is safe and has no recreational applications. In fact, many misinformed people, along with many recreational marijuana users, often brand CBD as “useless” because it cannot get them “high.”
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.

Laboratory evidence indicated that cannabidiol may reduce THC clearance, increasing plasma concentrations which may raise THC availability to receptors and enhance its effect in a dose-dependent manner.[21][22] In vitro, cannabidiol inhibited receptors affecting the activity of voltage-dependent sodium and potassium channels, which may affect neural activity.[23] A small clinical trial reported that CBD partially inhibited the CYP2C-catalyzed hydroxylation of THC to 11-OH-THC.[24] Little is known about potential drug interactions, but CBD-mediates a decrease in clobazam metabolism.[25]

"If there was good evidence that people were using e-cigarettes just to quit smoking, there would be wide support," Benowitz says. "The problem is most of the e-cigarette use in the U.S. is dual use with cigarettes." People use e-cigs in places or situations where they can't smoke, like in a restaurant, but continue lighting up when they can, he explains.

I was introduced to vaping from a friend who smoked 2-3 packages of cigarettes a day. I smoked only about a half package per day, but decided to try it. I always hated the way cigarettes made my lungs feel so heavy and my throat feel soar. As most people ,I was addicted to smoking from an early age in my life. I decided to try vaping, but still had a few cigarettes per day. As time went on I enjoyed the taste of the flavor and that it didn’t make your house smell. I now have several vape pens and enjoy many different flavors, and now free from regular cigarettes. I have heard of a disease that you can get from vaping called popcorn lung, I have yet to research this but that will be my next project.

CBD is otherwise most often used for its potential to provide calm and relaxation. On a chemical level, CBD is known to possess powerful antioxidant properties, which may contribute to reducing inflammation and relieving pain. Ongoing research and study are required to fully understand the potential of the cannabinoids therapeutic effects, but CBD may also help to:


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]
Everything you need to know about marijuana (cannabis) Marijuana, or cannabis, is the most commonly used illicit drug in the world. It alters the mood and affects nearly every organ in the body. With at least 120 active compounds, marijuana may have health benefits as well as risks. We describe these, addiction, and withdrawal. Learn more about cannabis here. Read now
