Chronic hashish use and mental disorder
C Stefanis, A Liakos, J Boulougouris, M Fink and AM Freedman
The authors compared 47 long-term users of hashish with a control group of
40 subjects matched for age, ethnic origin, education, etc., in order to
determine whether they differed significantly on psychiatric, physical
health, and demographic variables. There was a significantly higher
incidence of personality disorders, unemployment, and prison sentences in
the group of chronic users. However, in contrast to the findings of other
researchers, the hashish users did not have organic psychoses, nor did they
differ from control subjects in neurologic signs or EEG and echo
encephalogram patterns.
