Do you risk turning into a laid-back stoner, your grades and university ambitions fading in a haze? The answer is 'yes' according to public health research out of the University of Waterloo. It calls on high schools to help prevent this from happening. The study tracked 26,475 Ontario and Alberta students over time, measuring changes as some students began to smoke marijuana rarely, or more often. The study found that by the time students are smoking marijuana once a month, they are four times more likely to skip class, two to four times less likely to complete their homework, and half as likely to get high grades, compared to before they started smoking. By the time students escalate to smoking marijuana daily, they're half as likely to want to attend university compared to before they started smoking. Researchers conclude that smoking weed appears damaging to teens, whose brains are still developing. It's smart to stop them from doing it even as youths increasingly see the drug as benign. "The goal is really to prevent or to delay use as long as possible," lead author Karen Patte said. "We found that those who had started using became more likely to report lower grades, to skip class more often, less likely to complete their homework." The study published in the Journal of School Health arrives a year before Canada's Liberal government legalizes marijuana in July 2018. "The current system isn't working," Patte said. Students can easily access marijuana despite laws against it. Charging students with a crime "isn't going to help their future outcomes, either," she said. She pins her hopes on regulations meant to protect children, and on publicity around marijuana dangers. The study says "school-based prevention programs may ultimately benefit not only students' well-being but also their academic performance." But how to build an effective prevention program is still uncertain, Patte said. Local school boards point to Ontario's health curriculum. It addresses cannabis in Grade 6 and it teaches students about healthy habits in earlier grades. The Waterloo Catholic District School Board helped to prepare a regional drug strategy, and the Waterloo Region District School Board has addiction counsellors in some schools. "The key message for now is prevention is an ongoing process from Grade 1 right through to high school graduation," said John Shewchuk, spokesperson for the Catholic board. The UW study monitors students aged 13 to 18 as they progress from Grade 9 up until Grade 12. None of the students are from this region. Scholars measure changes on individuals. The large sample size is useful. But the study is not proof that smoking weed causes students to falter. A reverse explanation can't be ruled out: students who falter turn to smoking marijuana. Social factors could be in play. For example, students drawn to an outlaw lifestyle may demonstrate this by shunning school and smoking an illegal drug. The study found hints of social factors in comparing marijuana to alcohol. Students who turn to drinking also perform worse in school. Unlike marijuana smokers, they don't downscale their desire to attend university. This may be because alcohol is legal and its use is often celebrated in university culture. Scholars speculate that as marijuana gains acceptance it may more closely mirror alcohol: "Results raise the question of whether the image of particular substances accounts for their different relationships with future goals." - --- MAP posted-by: Matt
