Cannabis: Harm Reduction and Hyperbole

"The tricky part is that part of harm reduction will continue to be that you shouldn't be using this product."
"By being more honest and open that cannabis can be used responsibly it will add credibility to the messages that say, 'but you shouldn't really use it under these settings, and one of those is if you're a young person."
"[There is evidence supporting each of the proposed health warnings by Health Canada] and none of them -- except for the warnings around pregnancy and breastfeeding -- actually say people shouldn't use cannabis. That's harm reduction."
"[Most people use pot responsibly] but there is a reasonable number who can have problems controlling their use, and signs of daily use can be an indication of that."
David Hammond, professor, school of public health, University of Waterloo, Ontario

"[People tune out sensationalist scare tactics and condescending messages; abstinence-only propaganda -- and 'Just Say No' campaigns fail to resonate with youth...]"
"If they do find themselves struggling with use, they need supports they can use rather than judgement, or, worse, criminalization."

The group, Canadian Students for Sensible Drug Policy has undertaken an initiative of their own, to produce a "Sensible Cannabis Toolkit" information package which they have based on what they feel is realistic evidence-based information to help guide young adults in their conversations with adults when discussing the use of weed. Most pot users, they point out, do not use pot as a 'gateway' to transition to the use of harder drugs.

They also take issue with the use-associated mental health problems in the heavy use of cannabis concluding that there is an association with cognitive impairment and other mental health problems. "Any strong conclusions around causality" -- which came first? -- remain uncertain, according to their informative website.

Recently, a review of available literature associated with pot use led by researchers at the B.C. Centre on Substance Use discovered that what is believed to be a link to a lower IQ in later life among adolescent-use of high frequency, is belied by the findings of more recent studies concluding no association after controlling for social factors like background poverty and the neighbourhood that users grew up in.

Early efforts at Colorado public health after the state's 2014 legalization saw some of their informative harm-reduction efforts fall flat and face criticism by pot advocates for their condescending undertones. Leading Professor Hammond to the view that pot advertisements must reach beyond "use or not-use", to include information more specific such as that smoking adds toxicity in excess since THC levels in the pot currently in circulation are much higher than what prevailed during the Boomer era.


Health Canada is preparing to roll out a $5.1-million marijuana education tour to travel across the country in an effort to prepare the public before the cannabis legalization comes into effect in Canada by the target date of October 17. Plans are underway to set up exhibits at local events such as fairs, festivals and Canadian Hockey League arenas from July in the Maritimes and Northwest Territories before moving on to other provinces and territories.

Exhibits will be complete with climbing walls, interactive graffiti walls and similar such infrastructure in an effort to encourage people to to discover activities "that can give them a natural high, rather than using cannabis". "Ambassadors" will be tasked to "engage visitors in conversations about the health and safety facts on cannabis", to staff the exhibits.

A list of proposed pot packaging warning labels is being released by Health Canada. That cannabis smoking is harmful; that teens are at greater risk of harms; that people should not drive stoned; that women should not use if pregnant or breastfeeding (new links of pot exposure in the womb or through breast milk have been identified with stillbirth, preterm birth, low birth weight and poorer mental developing in children), are all driving the government's effort to ensure people are adequately informed of risks involved in indulging in cannabis.

Critics,  however, have highlighted one of the warnings for special attention; the warning that "up to one in two people who use cannabis daily will become addicted", has been seized upon as extravagantly unwarranted. Dr. Hammand and colleagues published a paper last year in the Canadian Journal of Public Health outlining their findings that a "very small proportion of Canadians report using cannabis to a degree that is problematic", with only two percent of the sample of respondents reporting the use of pot in the past three months seen to be at high risk of developing health or other problems.
