What marijuana does to your body and brain

When weed's active ingredient, THC, hits the brain, it causes brain cells to release the feel-good chemical dopamine.

Like any drug, marijuana has a variety of effects on the body — some positive, others negative.

While it's perhaps best-known for its more obvious effects like red eyes, food cravings, and its characteristic high, marijuana has also been linked with the potential to provide certain types of pain relief. Some research suggests it may even help control specific kinds of epileptic seizures.

Depending on how much and how often you use, marijuana's effects can vary widely.
