Marijuana use does NOT affect teenager’s IQ, says new study (but it does make you dumber as an adult)

Cannabis use does not affect teenager’s IQ, new research reveals.

Taking the drug between the ages of 12 and 18 does not cause adolescent’s intelligence to decline, a study found.

Yet, children with low IQs are more likely to use cannabis as teenagers, the research adds.

Drug researcher Ian Hamilton from York University told MailOnline: ‘This research murders an age-old myth about cannabis.’

Previous studies have revealed cannabis use affects teenager’s educational achievements, as well as increasing their risk of depression and psychosis.
