Until relatively recently (1980s), scientists believed that CBD was a natural precursor to the formation of THC, and since THC was a strictly controlled substance back then (it still is), it only followed that CBD should be equally strictly regulated. However, CBD is actually unrelated to the chemical chain that results in THC. They share some characteristics but are created via different paths. Again, unlike THC, CBD is considered a legal cannabinoid and is safe to consume in any amount and concentration.

The e-liquid in vaporizer products usually contains a propylene glycol or vegetable glycerin-based liquid with nicotine, flavoring and other chemicals and metals, but not tobacco. Some people use these devices to vape THC, the chemical responsible for most of marijuana's mind-altering effects, or even synthetic drugs like flakka, instead of nicotine.

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.
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]
With the rapid rise in the popularity of CBD in everything from vape juice to lattes, many people are asking- “what is CBD oil?”. To answer that question, let’s first answer the question- what is CBD? CBD, short for cannabidiol, is a compound found in hemp plants. CBD’s benefits are numerous, making it a popular supplement. We’ll explore the effects of CBD oil in more depth below, but in short, it interacts with receptors that keep the body balanced and running normally.
A disclaimer here: I am not a professional in this field. The symptoms I describe below and attribute to either to under or over dose of nicotine are information I have assembled by reading web sites and published studies; my advice is based only on that. I can not promise that they are absolute indications. Above all in your process of switching to vaping, listen to your body. If you can work out what it is telling you then that’s the best advice of all. vaping
