Tetrahydrocannobinol (THC) is a chemical in marijuana that causes intoxication. An analysis of 80 different readily available THC-free cannabidiol (CBD) products found that about 60% of these products did contain THC. The researchers note that most contained only trace amounts of THC, but these amounts can accumulate in the body and be detected by a drug test. The Partnership to End Addiction in New York City adds, “Consumers deserve accurate marketing claims and if they choose to buy CBD, to know exactly what’s in the product… It’s been like the Wild West for quite some time as CBD products proliferate, advertised for numerous maladies without research to substantiate it and without oversight on quality control.” Drug and Alcohol Dependence, June 2022
