From 2015 to July 2019, the FDA issued 48 warning letters to 23 American manufacturers of CBD products for false advertising and illegal interstate marketing of CBD as an unapproved drug to treat diseases, such as cancer, osteoarthritis, symptoms of opioid withdrawal, Alzheimer's disease, and pet disorders.[91][92] The FDA said that the letters were issued to enforce action against companies that were deceiving consumers by marketing illegal products for which there was insufficient evidence of safety and efficacy to treat diseases.[91] In July 2019, the FDA stated: "Selling unapproved products with unsubstantiated therapeutic claims — such as claims that CBD products can treat serious diseases and conditions — can put patients and consumers at risk by leading them to put off important medical care. Additionally, there are many unanswered questions about the science, safety, effectiveness and quality of unapproved products containing CBD."[91]


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.
However, when cannabinoids are taken externally, it’s difficult to distinguish between the clinically desirable effects and the therapeutically undesirable effects of various phytocannabinoids. This is because cannabinoid receptors send a variety of signals that often interconnect to coordinate the body’s functions, so it’s hard to tell them apart.
Hopefully, after reading this comprehensive guide, you now have a better understanding of what vaping is. No matter what benefits vaping has over smoking, the risks involved are still uncertain. For instance, most liquids contain nicotine, which is a habit-forming substance and can be poisonous if ingested. While we can’t claim that vaping is completely harmless, it does lack certain harmful ingredients present in normal cigarettes.
Convection vaping works by heating up the material by blowing hot air through it. The material is transformed into vapor without direct contact. Since the air flows through the material evenly, convection vaping results in a smooth taste; however, the vaporizer may take a while to reach the optimal temperature level. Convection vaporizers are usually more expensive.

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.
With that being said, one is not necessarily better than the other. CBD can be much more welcoming for those who do not want the potential high that comes with THC. THC may also offer more than just a high, with studies suggesting that it may possess health benefits of its own. More recently, evidence has suggested that THC and CBD can work together through what is known as the “entourage effect”. Taken together, CBD, THC, and the other compounds found in cannabis become more than the sum of their parts, amplifying their effects and working in synergy to support better health and well-being. It’s fine if you want just CBD on its own, but pairing your CBD with some THC may actually be good for you and give you whole plant benefits.

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.
3. You may feel a sore throat, dry mouth, and/or cold-like symptoms. For most people this passes after about a week. Drinking more liquids may help. Note that these are common symptoms of quitting smoking, related to tar. For a particular person they may or may not be aggravated by vaping. If these get very bad you should consider switching from vaping a PG based liquid (the most common liquids) to a VG based one or seeing a doctor (perhaps something else is causing the symptoms.)
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]

The symptoms of nicotine overdose are clearer indicators of what is happening in your body than the symptoms of withdrawal. This is because nicotine overdose has been studied a fair bit. Nicotine withdrawal has not been studied nearly as much. What has been studied a lot is cigarette withdrawal which is a different thing – it includes no longer inhaling a few thousand chemicals, not just nicotine.
Schizophrenia. Research on the use of cannabidiol for psychotic symptoms in people with schizophrenia is mixed. Some early research suggests that taking cannabidiol four times daily for 4 weeks improves psychotic symptoms and might be as effective as the antipsychotic medication amisulpride. But other early research suggests that taking cannabidiol for 14 days is not beneficial. The mixed results might be related to the cannabidiol dose used and duration of treatment.
In September 2018, following its approval by the FDA for rare types of childhood epilepsy,[12] Epidiolex was rescheduled (by the Drug Enforcement Administration) as a Schedule V drug to allow for its prescription use.[73] This allows GW Pharmaceuticals to sell Epidiolex, but it does not apply broadly and all other CBD-containing products remain Schedule I drugs.[73] Epidiolex still requires rescheduling in some states before it can be prescribed in those states.[76][77]

More important than legality is understanding if CBD is safe for you. While studies are still ongoing about the long-term safety of CBD usage, most experts agree that it is easily tolerated by most adults with no significant side effects on mood, physiology, or the central nervous system. Many CBD products, including oils and tinctures, also allow you to customize your serving size, which can help you avoid or mitigate any potential side effects.


Cannabidiol can be taken into the body in multiple ways, including by inhalation of cannabis smoke or vapor, as an aerosol spray into the cheek, and by mouth. It may be supplied as CBD oil containing only CBD as the active ingredient (no included tetrahydrocannabinol [THC] or terpenes), a full-plant CBD-dominant hemp extract oil, capsules, dried cannabis, or as a prescription liquid solution.[2] CBD does not have the same psychoactivity as THC,[9][10] and may change the effects of THC on the body if both are present.[7][8][9][11] As of 2018, the mechanism of action for its biological effects has not been determined.[8][9]

Nabiximols (brand name Sativex) is a patented medicine containing CBD and THC in equal proportions. The drug was approved by Health Canada in 2005 for prescription to treat central neuropathic pain in multiple sclerosis, and in 2007 for cancer related pain.[32] In New Zealand, Sativex is "approved for use as an add-on treatment for symptom improvement in people with moderate to severe spasticity due to multiple sclerosis who have not responded adequately to other anti-spasticity medication."[33]


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]

Vaping is the act of inhaling and exhaling the aerosol, often referred to as vapor, which is produced by an e-cigarette or similar device. The term is used because e-cigarettes do not produce tobacco smoke, but rather an aerosol, often mistaken for water vapor, that actually consists of fine particles. Many of these particles contain varying amounts of toxic chemicals, which have been linked to cancer, as well as respiratory and heart disease.
