Club drugs are associated with nightclubs, concerts, and all-night dance parties. Common club drugs include Ecstasy, GHB, Rohypnol, and ketamine. These drugs can cause dangerous short-term effects like confusion, anxiety, and blackouts, and long-term effects include permanent brain damage, respiratory failure, and death. Teens and young adults often attend "raves" where they are exposed to club drugs that they mistakenly believe are harmless.
