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.
The effects of smoking marijuana fade quickly, but the drug can be detected in the body for weeks and sometimes longer. How long it remains in the system depends on how often or how much marijuana the user has been smoking. The active ingredient in marijuana - Tetrahydrocannabinol or delta-9-THC or simply THC - enters the body's bloodstream rapidly after smoking marijuana.
