abstract="The association between cannabis use and psychosis is well established, with estimated odds ratios (ORs) of 1·4 for lifetime exposure and 2·1 for frequent use according to longitudinal population-based cohorts. These results seem to show a dose-response effect, but have not taken account of a key component of cannabis--its potency. In The Lancet Psychiatry, Marta Di Forti and colleagues address this gap with a case-control analysis of first-episode psychosis. Strengths of the study include the large sample of patients (n=410), an impressive response rate for participation (461 [76%] of 606 individuals) and appropriate control for confounding by gender, ethnicity, education, employment status, and other drug use.<p /> <p>Language: en</p>",
