The medical marijuana market is growing in the United States despite the fact that the Food and Drug Administration (FDA) has not yet approved any medical marijuana products. These marijuana-based products have not yet passed through the rigorous tests and clinical trials required for medical drug approvals in the United States. At the Federal level, marijuana is still considered an illegal Schedule 1 drug. Individual states, however, have laws in place for the legal use of medical marijuana, and in some states, for the use of recreational marijuana. Cannabidiol (CBD) products are also legally available in some US states as well as in many other countries. The market generates a lot of money, though much of that money is still considered a black market.
