Marijuana is a green, brown, or gray mix of dried, crumbled leaves from the marijuana plant.

Marijuana can be rolled up and smoked like a cigarette (called a joint) or a cigar (called a blunt). Marijuana can also be smoked in a pipe. Sometimes people mix it in food and eat it.

Marijuana can make you feel silly, relaxed, sleepy, and happy—or nervous and scared. It may change your senses of sight, hearing, and touch. Marijuana can make it hard to think clearly.
