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.
