Amid growing decriminalisation of cannabis use, a new study warns that daily cannabis use, especially of high potency, is strongly linked to the risk of developing psychosis, a mental disorder characterised by a disconnection from reality.
The findings, published in the journal the Lancet Psychiatry, are consistent with previous studies showing smoking pot with a high concentration of THC — over 10 per cent of the psychoactive substance within cannabis — has more harmful effects on mental health than the use of weaker forms.
