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]


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]

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.
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.

The flavor quality of your vaping experience will be determined by the type and brand of e-liquid you use. Put some thought into choosing your juices, and they can make or break the entire experience. Particularly as a beginner, it is advisable to choose well-known and reputable brands, as low-quality e-juices can contain harmful contaminants or unlisted ingredients.
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]

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]

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.”
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.

There has been little high-quality research into the use of cannabidiol for epilepsy. The limited available evidence primarily focuses on refractory epilepsy in children.[15] While the results of using medical-grade cannabidiol in combination with conventional medication shows some promise, they did not lead to seizures being eliminated, and were associated with some minor adverse effects.[15]

Similar to energy drinks and protein bars which may contain vitamin or herbal additives, food and beverage items can be infused with CBD as an alternative means of ingesting the substance.[48] In the United States, numerous products are marketed as containing CBD, but in reality contain little or none.[13][49] Some companies marketing CBD-infused food products with claims that are similar to the effects of prescription drugs have received warning letters from the Food and Drug Administration for making unsubstantiated health claims.[13][50] In February 2019, the New York City Department of Health announced plans to fine restaurants that sell food or drinks containing CBD, beginning in October 2019.[51]
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.)
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.
I love the written word, and in my career as a journalist, I strive to provide the facts about everything I write about. There are too many false and alarmist stories out there about life and vaping mainly. My mission is to make e-cigarettes less scary to people with informative articles and extensive research on not only the possible evils of cigarettes and Big Tobacco, but the objective side of e-cigs.
