Green, B., Young, R., Kavanagh, D. (2005) Cannabis use and misuse prevalence among
people with psychosis. British Journal of Psychiatry, 187, 306-313.
Conclusions The factor most consistently associated with increased odds of cannabis
prevalence was specificity of diagnosis. Factors such as consumption patters and
study design merit further consideration.

relapse in recent onset psychosis. British Journal of Psychiatry, 189, 137-143.
Conclusions The relationship between cannabis use and psychosis may be bidirectional,
highlighting the need for early intervention programmes to target cannabis use and
psychotic symptom severity in this population.
