This is called “Vaping”. The vapor is very similar to smoke, but it’s only water vapor. You get the same feel as if you are actually smoking, , a real throat hit, you still are putting a device in your mouth like a cigarette and you are even blowing smoke, known as vapor, out of your mouth like a cigarette and you get your “fix”, just like a real one.
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.
Until 2017, products containing cannabidiol marketed for medical purposes were classed as medicines by the UK regulatory body, the Medicines and Healthcare products Regulatory Agency (MHRA) and could not be marketed without regulatory approval for the medical claims. As of 2018, cannabis oil is legal to possess, buy, and sell in the UK, providing the product does not contain more than 0.3% THC and is not advertised as providing a medicinal benefit.
Various strains of "medical marijuana" are found to have a significant variation in the ratios of CBD-to-THC, and are known to contain other non-psychotropic cannabinoids. Any psychoactive marijuana, regardless of its CBD content, is derived from the flower (or bud) of the genus Cannabis. As defined by U.S. federal law, non-psychoactive hemp (also commonly-termed industrial hemp), regardless of its CBD content, is any part of the cannabis plant, whether growing or not, containing a ∆-9 tetrahydrocannabinol concentration of no more than 0.3% on a dry-weight basis. Certain standards are required for legal growing, cultivating, and producing the hemp plant. The Colorado Industrial Hemp Program registers growers of industrial hemp and samples crops to verify that the dry-weight THC concentration does not exceed 0.3%.

It is for this reason that all the finished hemp goods that you see for sale in America, from food products to clothing to building materials, are part of an imported hemp industry that has surpassed $688 million annually. The size of this import industry is one of the major catalysts for hemp legalization in the U.S. As a renewable source of a range of products, hemp provides an exciting new step in American agriculture.
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.
