Meta permits ketamine discussions for medical purposes, but prohibits illicit use references.

Meta allows posts about ketamine, a Schedule 3 drug with both medical and recreational uses, despite potential dangers. Struggling to regulate health product posts, Meta's rules on ketamine are context-dependent: pharmaceutical discussions allowed, illicit drug use references prohibited. Google requires prescription drug ad certification, prohibits promoting "highs"; TikTok bans unauthorized pharmacy ads, promo of prescription drug abuse.
