Marijuana plants have compounds that may have therapeutic benefit. Some states have legalized its use for certain disorders. One of these is delta-9-tetrahydrocannabinol (THC) which is a mind altering compound, also called psychoactive. THC is similar in chemical composition to naturally occurring brain chemicals.
