Cannabis, also known as marijuana, is used to treat some symptoms related to cancer. It’s made from the flowers, leaves, and resin (sticky chemical) of the Cannabis sativa plant.

Cannabis comes in many forms, including vape pens, pills, lozenges, oils, teas, and powder. It isn’t a prescription medication. It can be taken orally (by mouth), by smoking, or by vaporizing.

A licensed doctor or advanced practice provider (APP) must certify you if you want to buy medical marijuanafrom a registered dispensing facility (a place where medical marijuana is sold).
