Schulich School of Medicine & Dentistry researchers have shown that chronic exposure during adolescence to tetrahydrocannabinol (THC), the main psychoactive component of cannabis, may induce long-lasting memory impairments and increased anxiety levels.
The study, published in the journal Neuropsychopharmacology,Neuropsychopharmacology<\/i>The study, published in the journal Neuropsychopharmacology,<\/a> uses a rodent model to pinpoint two different parts of the brain\u2014the dorsal and the ventral regions in the hippocampus\u2014and shows evidence of different sets of abnormalities in each region\u202ffollowing THC exposure.
The researchers identified several key molecular and neuronal anomalies in specific regions of the hippocampus\u202fthat might be independently responsible for the cognitive and emotional side effects. The study confirms previous work from their lab that shows THC exposure during adolescence can induce long-lasting disturbances.
“Following the legalization<\/a> of cannabis, there is evidence of a reduction in perceived risks associated with cannabis use. There is a need to expand knowledge on the potential negative consequences of cannabis exposure during adolescence and this study addresses some of those gaps,” said Marta De Felice, who emphasized the need to have crucial scientific evidence to inform public health policy
“Adolescents consuming cannabis may not be thinking of the negative long-term impacts. Our findings suggest adolescent cannabis use<\/a> may affect cognitive and emotional functions through different brain pathways,” said Laviolette. “The detailed anatomical findings of the study give us a chance to use more targeted interventions that might reverse the long-lasting impairments and symptoms following cannabis exposure during adolescence.”<\/span><\/p>\n
