WHAT IS MEDICAL CANNABIS
U.S. federal law prohibits the use of marijuana. However, many states allow medical use to treat pain, nausea and other symptoms.
Medical marijuana is a term for derivatives of the Cannabis sativa plant that are used to ease symptoms caused by certain medical conditions. Medical marijuana is also known as medical cannabis.
Cannabis sativa contains many active compounds. The best known are delta-9 tetrahydrocannabinol (THC) and cannabidiol (CBD). THC is the primary ingredient in marijuana that makes people "high."
