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.
No matter how you use marijuana, the drug can cause immediate and long-term effects, such as changes in perception and increased heart rate. Over time, smoking marijuana may cause chronic cough and other health issues. The effects of marijuana on the body are often immediate. Longer-term effects may depend on how you take it, how much you use, and how often you use it. The exact effects are hard to determine because marijuana has been illegal in the U.S., making studies difficult and expensive to conduct.
