Teen Cannabis Use Linked To Lower IQ

 Persistent cannabis use among teenagers under 18 years of age results in neuropsychological decline, which persists even after they stop smoking, researchers from the USA and UK reported in Proceedings of the National Academies of Sciences. The authors added that the decrease in IQ did not seem to occur among persistent cannabis users who started after the age of 18.

Persistent cannabis use means daily pot smoking.

They found that
early-onset regular pot users had IQs 8 points lower than their counterparts who never smoked or started after they were 18 years of age.

The authors explained that as progressively fewer teenagers today believe cannabis harms health, the age at which people start using it on a daily basis has been dropping.
