Artigo Psicose e Maconha

Prospective cohort studies have found that early-onset cannabis use is associated with an increased risk of psychosis-related outcomes.17 Based on these studies and a range of other lines of evidence, reviews have generally concluded that cannabis use is a risk-modifying factor for these outcomes (ie, cannabis use is causally related to psychosis-related outcomes).813 However, there are lingering concerns that the association may reflect methodological biases and unmeasured residual confounding.1415 In a recent meta-analysis, Moore and colleagues11 noted that after adjusting for various methodological issues, there were often substantial reductions in the effect size between cannabis use and later psychosis-related outcomes.

Because the pooled effect size reported by Moore and colleagues was modest (adjusted odds ratio, 1.41; 95% confidence interval [CI], 1.20-1.65), the role of residual confounding cannot be discounted. In light of the limitations of observational epidemiology,16 it is understandable that there is debate about the public health implications of these findings.15, 17
