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]

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.

Many of these particles contain varying amounts of toxic chemicals, which have been linked to cancer, as well as respiratory and heart disease.

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.

If you can work out what it is telling you then that’s the best advice of all. vaping
