Cannabis Exposure During Adolescence Causes Brain Damage and Schizophrenia .The findings particularly hold true for people who have a genetic susceptibility to the mental health disorder. The cannabis could activate the disorder.

Asaf Keller, of the University Of Maryland School Of Medicine, said the results reveal the possible dangers teens could face from smoking cannabis.

Schizophrenia For the study, the scientists exposed young mice to very low amounts of the active ingredient in marijuana for 20 days. They found that their brain activity was impaired, with the damage continuing into adulthood.

“In the adult mice exposed to marijuana ingredients in adolescence, we found that cortical oscillations were grossly altered, and they exhibited impaired Schizophrenia cognitive abilities,’ said Raver, a PhD candidate at the University Of Maryland School Of Medicine. ‘We also found impaired cognitive behavioural performance in those mice. The striking finding is that, even though the mice were exposed to very low drug doses, and only for a brief period during adolescence, their brain abnormalities persisted into adulthood.”

They gave the marijuana to adult mice that were never exposed to the drug before. They found that their cortical oscillations and the ability to perform cognitive tasks remained normal, which implied that when the brain is exposed to the drug during critical teenage years, it impairs brain function.

It is also the area most affected in schizophrenia.”
