psychosis is not a defining feature of BIP. Therefore, most analyses relate cannabis use to SCZ and BIP, not psychosis.

Additionally, psychotic disorders and cannabis use share environmental factors, which may contribute to their covariation.60 Further work is required to disentangle shared genetics from environmental influences.
