E-cigarettes aren't thought of as 100% safe, but most experts think they're less dangerous than cigarettes, says Neal Benowitz, MD, a nicotine researcher at the University of California at San Francisco. Cigarette smoking kills almost half a million people a year in the United States. Most of the harm comes from the thousands of chemicals that are burned and inhaled in the smoke, he explains.

Cannabidiol is a chemical in the Cannabis sativa plant, also known as marijuana. Over 80 chemicals, known as cannabinoids, have been identified in the Cannabis sativa plant. While delta-9-tetrahydrocannabinol (THC) is the major active ingredient, cannabidiol makes up about 40% of cannabis extracts and has been studied for many different uses. According to the U.S. Food and Drug Administration (FDA), because cannabidiol has been studied as a new drug, products containing cannabidiol are not defined as dietary supplements. But there are still products labeled as dietary supplements on the market that contain cannabidiol. The amount of cannabidiol contained in these products is not always reported accurately on the product label.

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.
Cannabidiol has antipsychotic effects. The exact cause for these effects is not clear. But cannabidiol seems to prevent the breakdown of a chemical in the brain that affects pain, mood, and mental function. Preventing the breakdown of this chemical and increasing its levels in the blood seems to reduce psychotic symptoms associated with conditions such as schizophrenia. Cannabidiol might also block some of the psychoactive effects of delta-9-tetrahydrocannabinol (THC). Also, cannabidiol seems to reduce pain and anxiety.
As you may know, industrial hemp and marijuana come from the same genus of flowering plant– cannabis. The term “genus” essentially refers to a sub-family of plants and not a single species. This means that there may be multiple types of the cannabis plant, which are all cannabis but have remarkable differences. So, in terms of scientific classification, multiple species can exist within a single genus, and that’s exactly the case with cannabis.

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.
We’ve established the fact that naturally occurring CBD is the same CBD regardless of the plant it came from. However, CBD and CBD oil are not in fact the same thing. As we’ve seen above, CBD is a chemical compound with sharply defined characteristics, while CBD oil is a mixture of various natural substances as they are derived from the plant of cannabis.

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]
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.
"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.

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.

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]
