Psychologist and cannabis-use researcher Franco Vaccarino told Tuesday's Cannabis on Campus forum that young people need special attention because their brains don't fully develop until age of 25. Vaccarino, a principal editor of "The Effects of Cannabis Use during Adolescence" report in 2015, said brains undergo dramatic changes during adolescence and youth are vulnerable to drug use. With high drug use, there is an increased risk for mental illness later in life, he said. Vaccarino, who is also president of the University of Guelph, prefaced his remarks by stating that much of what he had to say related to early and frequent marijuana use and that "there are significant differences between frequent and infrequent use." Still, Canada has the highest number of young users of marijuana in the world, although their alcohol consumption is far higher, he said, adding one in 20 Canadian youth met the criteria for cannabis abuse in recent studies. "Early and regular cannabis use leads to earlier onset of psychotic symptoms and it is a major risk factor for developing schizophrenia," he said. "I understand that various factors have to be brought to bear on (legalizing marijuana) policy and that health is just one aspect. But wherever we land, we need to prepare the terrain first." Panel member Michael DeVillaer, a Mac professor and cannabis law researcher, spoke on the misconceptions about "decriminalization" and "legalization," and how they're different. He said young people are particularly vulnerable to getting a criminal record for possession in the next two years it will likely take to legalize marijuana after the federal government introduces legislation this summer. Having a criminal record can be damaging and have a significant impact on people's lives, DeVillaer said. He estimated a potential 50,000 young Canadians could get a criminal record the next two years for something that will soon be legal. "One solution proposed is to decriminalize it now," he said. "In the next two years, people are in peril, even with the occasional use - and all cannabis users need to keep that in mind." In discussing how Mac can deal with legalization, incoming dean of sciences Maureen MacDonald said: "All of this is far out of my comfort zone. Mental health is an area many faculty are very uncomfortable with, and now to add this layer adds a new complexity." She too wondered how legalization will affect student learning. "This year, there was a dramatic increase in anxiety among students. I don't know where this is coming from, but when we add substance abuse, it's going to be more difficult." Dr. Catharine Munn - who leads a Mac team that works to build resilience in students - agreed the university needs to prepare for legalization. - --- MAP posted-by: Matt
