NOT EVERY TIME! –

June 8, 2024 – This new analysis finds similarly, with young adults and women, people with pre-existing mental health conditions such as bipolar disorder found to be more at risk of psychosis than others. Individuals who had been exposed to the drug earlier and more frequently than others were also not at any higher risk of psychosis in this particular analysis of acute psychotic episodes. Daily use may still carry a higher risk of developing psychosis in the long run, though.

And of all the demographic factors analyzed, only age (younger) and gender (female) showed a correlation with psychotic episodes; education level and socioeconomic status had no apparent effect.

Tabea Schoeler, a statistical geneticist at the University of Lausanne in Switzerland, and colleagues selected 162 high-quality studies for their analysis.

Most of the 201,283 participants had been part of observational studies assessing the experiences of recreational cannabis users, and looking for links to demographic, social, and genetic factors.

Around 15 percent had participated in studies testing medicinal cannabis products and documenting their side effects, while a slim 1 percent had been involved in experimental studies studying the effects of THC in healthy volunteers.
