Teenagers who smoke cannabis damage their brains for LIFE and may be more likely to develop schizophrenia
- U.S. study found that mice exposed to even small doses of marijuana for 20 days suffered lasting brain damage into adulthood
- Results highlight how teenagers who regularly smoke weed may have a greater risk of developing schizophrenia
Teenagers who regularly smoke cannabis suffer long lasting brain damage and are in much greater danger of developing schizophrenia.
American researchers say the drug is particularly dangerous for a group of people who have a genetic susceptibility to the mental health disorder - and it could be the trigger for it.
Asaf Keller, of the University of Maryland School of Medicine, said the results highlight the dangers of teenagers smoking cannabis during their formative years.
The study, published in the journal Neuropsychopharmacology, exposed young mice to the active ingredient in marijuana for 20 days.
It found that their brain activity was impaired, with the damage continuing into adulthood.
The past 20 years has seen major controversy about the long-term effects of marijuana, with experts divided over its long-term effects on teenagers.
