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.
The vast majority of vapers use e-liquids, but other common materials include waxy concentrates and dry herbs. Different vaporizers support the vaping of different materials. For example, e-liquids vaporizers have a cartridge or tank, while a dry herb vaporizer will have a heating chamber. Multipurpose vaporizers allow you to vape different materials simply by switching cartridges.
While marijuana is bred with the only purpose of maximizing its THC concentration, industrial hemp always has trace amounts of THC and naturally occurring high amounts of CBD (it has the highest CBD/THC ratio of all cannabis strains, even Cannabis ruderalis) This means that industrial hemp’s chemical profile makes it incapable of inducing intoxicating effects and getting you “high” from ingesting it.
