Family First Comment: Last week’s issue of The Lancet Psychiatry published a meta-analysis of 15 studies that demonstrate a single dose of THC induces positive (including delusions and hallucinations), negative (such as blunted affect and amotivation), and general (including depression and anxiety) psychiatric symptoms. “These findings highlight the acute risks of cannabis use, which are highly relevant as medical, societal, and political interest in cannabinoids continues to grow,” say the researchers.


Last week’s issue of The Lancet Psychiatry published a meta-analysis of 15 studies that demonstrate a single dose of THC induces positive (including delusions and hallucinations), negative (such as blunted affect and amotivation), and general (including depression and anxiety) psychiatric symptoms.

CBD does not induce such symptoms, nor does it moderate the effects of THC as is commonly believed.

“These findings highlight the acute risks of cannabis use, which are highly relevant as medical, societal, and political interest in cannabinoids continues to grow,” say the researchers. The findings “highlight the potential risks associated with the use of cannabis and other cannabinoids that contain THC for recreational or therapeutic purposes.”

This week’s issue contains a commentary which concludes, “There is sufficient evidence to warn people that using THC could increase their risk of developing psychiatric symptoms or even a psychotic illness.”
