  1. Study Says Marijuana has Lasting Adverse Effects

    Smoking pot as a teenager could have long-term consequences for one’s intelligence and achievement, says a new review of published findings in the New England Journal of Medicine. The review, authored by scientists from the National Institute on Drug Abuse (NIDA), reports that regular pot smoking from an early age is associated with a lower IQ and impaired critical thinking even if users quit smoking as adults. Marijuana use by teenagers is also linked to poor grades, an increased chance of dropping out of school, and a greater vulnerability to using other drugs, according to the review.
