Explanation
Marijuana is a commonly used illegal drug made from dried leaves of the hemp plant. Smoking marijuana creates a high. Marijuana is a drug that is mostly smoked — in a joint, a bowl, a bong, or other device — but sometimes it can be eaten. Marijuana is illegal, but it is considered a "soft drug" — as opposed to hard drugs like heroin or cocaine, which are killers. People call marijuana "pot" and "weed" and a hundred other slang terms. There's also medical marijuana, which sick people, especially cancer patients, can get to relieve their pain.
