Drug 'doubles mental health risk'

BBC

Smoking cannabis virtually doubles the risk of developing mental illnesses such as schizophrenia, researchers say.

The New Zealand scientists said their study suggested this was probably due to chemical changes in the brain which resulted from smoking the drug.

The study, published in the journal Addiction, followed over 1,000 people born in 1977 for 25 years.
