Abstract

Hallucinogen persisting perception disorder is a disorder of uncertain aetiology occurring mainly after ‘classical’ hallucinogen use ( ie mescaline, psilocybin, dimethyltryptamine and LSD) use. Here, the authors describe the case of a boy with similar symptoms developing after he reported using cannabis seven times.
