No Drugs, No Smoking, No Alcohol - Prohibition Signs for Health & Safety #2809 (License: Personal Use)

This image displays four standardized prohibition signs arranged in a 2x2 grid, each featuring a bold red circle with a diagonal slash over a black silhouette icon. The icons represent cannabis leaf, lit cigarette, wine bottle with glass, and hypodermic syringe-symbolizing bans on marijuana, smoking, alcohol consumption, and intravenous drug use respectively. These signs are widely used in regulatory, educational, and institutional contexts to enforce substance-free policies.

Used on signage in hospitals, schools, government buildings, rehabilitation centers, and public transport to communicate strict no-substance policies; aligns with user intent seeking visual compliance aids or educational materials about substance abuse prevention.
