Pot Smokers 5 Times More Likely To Develop Psychosis

A British study released Monday suggested that the risk of psychosis was five times higher for regular users of cannabis, adding to a growing body of evidence linking drug use and mental health disorders.

The six-year study published in the medical journal The Lancet reported on 780 people living in south London, 410 of whom were being treated for conditions including schizophrenia and bipolar disorder.

The reports lead author was Marta Di Forti from the Institute of Psychiatry, Psychology and Neuroscience at Kings College London, who warned about the growing use of skunk a powerful type of cannabis.

Compared with those who had never tried cannabis, users of high potency skunk-like cannabis had a threefold increase in risk of psychosis, she said.

The risk to those who use every day was even higher a fivefold increase compared to people who never use, she added in a statement.

Psychosis is a mental health problem and the symptoms include hallucinations and delusions.

In England, about one new case of psychosis is diagnosed for every 2,000 people every year.

This paper suggests that we could prevent almost one-quarter of cases of psychosis if no one smoked high potency cannabis, said Robin Murray, professor of psychiatric research at Kings College London and a senior researcher for the study.

This could save young patients a lot of suffering and the NHS (National Health Service) a lot of money, he said.

The study was based on 410 patients who reported psychosis between 2005 and 2011. A further 370 healthy participants from the same area of south London were included for comparison.
