title: Psychological adverse effects of cannabis smoking: a tentative classification.
abstract: This paper stresses the need for an early definition and description of the "deviant" cannabis smoker in North America. Attention is called to the fact that on this continent heavy smokers have not yet been separated as "problem" users from other smokers.A comprehensive review of possible psychological adverse effects of the drug is made. The following classification is suggested: a) Severe intoxications, b) Pathological intoxications, c) Acute cannabis psychoses, d) Subacute and chronic cannabis psychoses and e) Residual conditions.
