Fornication and delusion of persecution, both are together seen in -

This question is tricky one as tactile hallucination (fornication) and delusion of persecution are seen both in cocaine as well as amphetamine abuse. Read the question carefully, examiner has asked about the presence of fornication and delusion of persecution together. In amphetamine abuse these two do not occur together → fornication (tactile hallucination) is seen in chronic abuse, where as paranoid ideation (delusion of persecution) occurs in acute intoxication. On the other hand both delusion of persecution and fornication are seen together in chronic cocaine abuse. "Cocaine abuse can present with auditory hallucinations, tactile hallucination including fornication and paranoid delusion (delusion of persecution)" .
