A new study has found that young people who use cannabis before the age of 18 end up with fewer academic qualifications.
The study looked at 6,000 young people in New Zealand and Australia.
Researchers found the young people were more likely to fail high school, less likely to enter university and less likely to get a university degree if they used cannabis.
The research was based on the findings of three studies; including the University of Otago's long running health and development study.
The research adds to the growing body of evidence linking early cannabis use with educational underachievement.
