The objective of this study is to investigate cognitive performance in a first-episode psychosis
sample, when stratifying the interaction by cannabis use and familial or non-familial psychosis.
Hierarchical-regression models were used to analyse this association in a sample of
268 first-episode psychosis patients and 237 controls. We found that cannabis use was
associated with worse working memory, regardless of family history. However, cannabis
use was clearly associated with worse cognitive performance in patients with no family history
of psychosis, in cognitive domains including verbal memory, executive function and
global cognitive index, whereas cannabis users with a family history of psychosis performed
better in these domains. The main finding of the study is that there is an interaction between
cannabis use and a family history of psychosis in the areas of verbal memory, executive
function and global cognition: that is, cannabis use is associated with a better performance
in patients with a family history of psychosis and a worse performance in those with no family
history of psychosis. In order to confirm this hypothesis, future research should explore
the actual expression of the endocannabinoid system in patients with and without a family
history of psychosis. [--]
