One of the enduring myths about marijuana is that it is \u201charmless\u201d and can be safely used by teens.<\/p>\n
Many high school teachers would beg to disagree, and consider the legalization of marijuana to be the biggest upcoming challenge in and around schools. And the evidence is on their side<\/p>\n
As an education researcher, I have visited hundreds of schools over four decades, conducting research into both education policy and teen mental health. I\u2019ve come to recognize when policy changes are going awry and bound to have unintended effects.<\/p>\n
As Canadian provinces scramble to establish their implementation policies<\/a> before the promised marijuana legalization date of July 2018<\/a>, I believe three major education policy concerns remain unaddressed.<\/p>\n These are that marijuana use by children and youth is harmful to brain development, that it impacts negatively upon academic success and that legalization is likely to increase the number of teen users.<\/p>\n \u2018Much safer than alcohol\u2019<\/strong><\/p>\n Across Canada, province after province has been announcing its marijuana implementation policy, focusing almost exclusively on the control and regulation of the previously illegal substance. This has provoked fierce debates over who will reap most of the excise tax windfall and whether cannabis will be sold in government stores or delegated to heavily regulated private vendors<\/a>.<\/p>\n All of the provincial pronouncements claim that their policy will be designed to protect \u201cpublic health and safety\u201d and safeguard \u201cchildren and youth\u201d from \u201charmful effects.\u201d<\/p>\n However, a 2015 report from the Canadian Centre on Substance Abuse cites rates of past-year cannabis use ranging from 23 per cent to 30 per cent among students in grades seven to 12 in Ontario, Quebec, New Brunswick, Nova Scotia, and Newfoundland and Labrador during 2012-2013. And notes that, \u201cof those Canadian youth who used cannabis in the past three months, 23 per cent reported using it on a daily or near daily basis.<\/a>\u201d<\/p>\n The report also describes youth perceptions of marijuana as \u201crelatively harmless\u201d and \u201cnot as dangerous as drinking and driving.\u201d<\/p>\n Early-onset paranoid psychosis<\/p>\n <\/p>\n
