Marijuana, "pot," or "weed," is the most commonly used illegal drug. Many abusers try to convince others that pot is harmless fun, but don’t be fooled. There’s plenty of harm in marijuana, and no one is immune.

Marijuana is psychologically addictive. As with any addictive drug, users build "tolerance" for marijuana – the need for more of the drug over time just to feel the original effects. The longer someone uses, the more time and money he or she spends on the drug, and the more damage it does.

Some users defend marijuana, saying it’s okay because it grows naturally. Yes, so does poison ivy, but you wouldn’t want to smoke it. Marijuana causes increasing deterioration in mental ability, and motivation, causes reproductive damage, and can increase the user’s risk of lung or oral cancer.
