Myths vs. Realities: Exploring the world of cannabis use

It’s been 5 years since cannabis was legalized for recreational use in Canada.

While it is legal, using cannabis is not without harm or risk.

James MacKillop is the director of the Michael G. DeGroote Centre for Medicinal Cannabis Research at McMaster University, director of the Peter Boris Centre for Addictions Research at St. Joseph's Healthcare Hamilton and a professor in the Department of Psychiatry & Behavioural Neurosciences.

MacKillop says there are many myths about cannabis and cannabis use, one of the most common being cannabis is not addictive.

Among those who use cannabis, roughly one in 10 develop cannabis use disorder (CUD), says MacKillop. The rate doubles in people who start using early as teenagers and increases to as high as 50 per cent among those who use cannabis daily.

While there’s no amount of cannabis known to have a lethal effect, overconsumption can lead to negative consequences like delirium or psychosis.

MacKillop adds that an important nuance is most negative consequences happen to a subset of people who use cannabis heavily, frequently and products that are high in Delta 9 THC – the psychoactive ingredient in cannabis.

MacKillop says this video is not about being pro-cannabis or anti-cannabis but about empowering people to make good decisions based on the facts.
