Cannabis use linked to academic failure

Stuff co.nz 10 September 2014
Cannabis use among teens has long-term harmful consequences, a damning new study shows.

The study, published in the Lancet, shows daily cannabis users under the age of 17 were 60 per cent less likely to complete high school or attend university and were nearly seven times more likely to attempt suicide.

Daily users were also 18 times more likely to become addicted to cannabis and eight times more likely to use other illicit drugs.

Researchers from three large, long-running studies in Christchurch and Melbourne combined data to investigate the link between cannabis use in adolescence and outcomes later in life.

Professor David Fergusson, leader of the University of Otago’s Christchurch Health and Development Study (CHDS), said the latest research was the largest single consistent study ever done on adolescent use of cannabis.

Moves to legalise cannabis could put adolescents at increased risk of harm, and “should be carefully assessed against the potential for increasing the availability and/or use of cannabis to young people”, he said.

The most significant finding was the effect of regular cannabis use on educational achievement, he said.

Legalising cannabis risky for teens – study
3News 10 September 2014
Teenagers who use cannabis daily are seven times more likely to attempt suicide and 60 percent less likely to complete high school than those who don’t, latest research shows.

It also found teenage users of cannabis are 60 percent less likely to get a university degree and more likely to use other illicit drugs.

The report, published in the latest edition of medical journal The Lancet, combined data from three long-running Australasian studies that examined associations between cannabis use in adolescence and outcomes in later life.

One of the studies was the University of Otago’s Christchurch Health and Development Study (CHDS).
