Cocaine abuse and delusions of parasitosis

Cutis. 1988 Oct;42(4):273-4.


We report two persons in their thirties with the shared delusion of parasitosis. Both abused cocaine, and both recovered from their delusions after a period of abstinence. Although the literature does not stress that a specific cause is usually found for delusions of parasitosis, this may be changing for persons in groups among whom cocaine and possibly other illicit drug use is common. It is a service to these desperate patients to establish their confidence and then discretely ask about the use of illegal drugs, especially cocaine.
