A history of ketamine
Anaesthetic medicine, veterinary and emergency use, club markets and new clinical research.
Anaesthesia
Ketamine was developed as a dissociative anaesthetic and has enduring clinical value. Evidence note: Established.
Non-medical markets
Recreational use expanded in music and nightlife settings and later beyond them. Evidence note: Established.
Changing clinical interest
Ketamine and related medicines have been researched or authorised in tightly controlled mental-health contexts. Evidence note: Established.
Why this history matters now
Clinical ketamine does not make non-medical use risk-free. Present concerns include dependence and serious urinary-tract harm with repeated heavy use.
Myths, disputes and uncertainty
Popular drug histories often compress complex cultural, commercial and political developments into a single inventor, date or scandal.
