Marijuana comes from the hemp plant Cannabis sativa. It has an active ingredient called THC that makes you feel high. THC and other compounds in marijuana can also affect the way your body works. Most people smoke the plant's dried leaves, flowers, stems, and seeds. But marijuana can also be mixed into food (like brownies, cookies, and lollipops), brewed as a tea, or inhaled with a vaporizer.
Marijuana has been used as a medicine for thousands of years. THC is the main active ingredient in marijuana. When THC enters the body it stimulates receptors in the brain and can reduce pain and increase appetite.
