Some manufacturers ship CBD products nationally, an illegal action which the FDA did not enforce in 2018, with CBD remaining the subject of an FDA investigational new drug evaluation, and is not considered legal as a dietary supplement or food ingredient as of December 2018. Federal illegality has made it difficult historically to conduct research on CBD. CBD is openly sold in head shops and health food stores in some states where such sales have not been explicitly legalized.
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.
Selective breeding of cannabis plants has expanded and diversified as commercial and therapeutic markets develop. 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. 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.
Since industrial hemp is naturally rich in CBD and has been bred to have only trace amounts of THC, many people today are turning to industrial hemp products as an alternative to medical marijuana. Medical marijuana is not legal in all states in the US and many countries worldwide, while products made from industrial hemp can be a safe and legal alternative. You can get many of the same beneficial effects of medical marijuana from industrial hemp products without getting “high.”

Unlike drugs approved by the FDA, the manufacturing process of these products has not been subject to FDA review as part of the drug approval process, and there has been no FDA evaluation of whether these products are effective for their intended use, what the proper dosage is, how they could interact with FDA-approved drugs, or whether they have dangerous side effects or other safety concerns.

Similar to energy drinks and protein bars which may contain vitamin or herbal additives, food and beverage items can be infused with CBD as an alternative means of ingesting the substance. In the United States, numerous products are marketed as containing CBD, but in reality contain little or none. Some companies marketing CBD-infused food products with claims that are similar to the effects of prescription drugs have received warning letters from the Food and Drug Administration for making unsubstantiated health claims. In February 2019, the New York City Department of Health announced plans to fine restaurants that sell food or drinks containing CBD, beginning in October 2019.
