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.
When a person smokes marijuana, THC quickly passes from the lungs into the bloodstream. The blood carries the chemical to the brain and other organs throughout the body. The body absorbs THC more slowly when the person eats or drinks it. In that case, they generally feel the effects after 30 minutes to 1 hour.
