No Alcohol and No Drugs Prohibition Signs - Safety & Compliance Visuals #1411921 (License: Personal Use)

This image displays two standardized red-circle prohibition symbols on a white background. The left icon features a wine glass crossed out, indicating alcohol禁; the right combines a cannabis leaf, pill, and syringe-all crossed out-to signify bans on controlled or illicit substances.

Commonly used on workplace safety posters, school handbooks, event entry signage, healthcare facility notices, and government public health campaigns to communicate substance restrictions clearly and instantly to diverse audiences.
