Cannabis is a psychoactive drug derived from the Cannabis sativa plant. Users can smoke the dried flowers and leaves as marijuana or make them into an oil or resin.
It slows down the central nervous system, making users feel relaxed and euphoric. Smoking too much or too often can have negative side effects such as confusion, anxiety or even psychosis.
While there are over 100 active compounds in cannabis, the most interesting to medical researchers are THC—delta-9 tetrahydrocannabinol and CBD—cannabidiol.
Making the medical grade
