Materials from the Public Health Agency of Canada & Centre for Addiction and Mental Health

The Public Health Agency of Canada, together with the Centre for Addiction and Mental Health, has developed some informational materials for Canadian health professionals based on the Lower-Risk Cannabis Use Guidelines— an evidence-based tool to guide the choices of Canadians who use cannabis, with the aim of reducing health-related harms.

Cannabis & your health – 10 ways to reduce risks when using Poster Link
10 ways to reduce risks to your health when using cannabis Brochure Link
Lower-Risk Cannabis Use Guidelines (LRCUG) for Youth Webpage Link
Presentation on LRCUG to support educating health professionals PowerPoint Expected: November
Evidence of the LRCUG to provide a more detailed reference tool to health professionals Summary Expected: November

These materials were created based on feedback received from the Health Professional Forum Sub-Group on Cannabis Risks and Harms, and a steering committee that was specially set up to oversee the creation of these products.
Two more resources aimed at health professionals are expected next month.

As when all new drugs become available/more widely available, there is bound to be a lot more to learn. We will continue to work with specialty societies, partners in health care and in the medical education system to support physicians’ training and professional development in this area. - Andrew

I have been a practicing physician with insight in the use of drugs of addiction starting with Cacaine for local anesthesia, oral and parenterral use of natural & synthetic opioids , intrathecal opioids and high dose opioids in cardiac anesthesia & in pain relief in victims of intractable pain of cancer. Each & Every user is a potential addict with possibility of physical dependence unless other use prooven. As the roaring rates of loss of life due to opioid overdose in the USA , the experience with exclusive availability & use of the once wonder dug hydocodone in the USA , the current evidence that there is no safe dose of alcohol in the Hyman species and the experience of tobacco use indicate, in my educated opinion, Routine availability & use of Canabis is another time bomb. There may be a small potential for therapeutic use of Canabidiol. I do not see that for THC; but the stuff of the introduction of ever more potent Canabis as an ongoing phenomenon, we may be facing the beginning of the decay of human race & civilization. I also have the insight from having had one alcohol addict & one tobacco addict in my family; one of this in any family is enough. Drug heads & alcoholics are profit makers for business; they create poverty , distruction and death on an increasingly on going basis in the community of the human race and contribute to population control. That would be like Kalidassan climbing the tree and ordering some one to cut the tree down to how fast one can cut the tree down. Have thought hard enough before this giant step of legalizing Canabis Fest? Mind you; we have no real or affordable answer to the problem of drug addiction or for that matter addiction to anything! I thought we have enough ongoing problems facing the Human race; then comes the legalization of Canabis! I have had the best part of my education to by becoming a halfway decent Physician at McGill and continue to have a high opinion of Canadians. Am I wrong? Kunnathu P. Geevarghese, MD,FRCPC,FRCA

I agree , but other Cannabinoid , such as CBC, CBD , CBD and it’s derivative can also causes harm. Other methodology to differentiate chronic vs acute user, needed to be explored
S.Edward Said MD FRSC | October 17, 2018
Cannabis has a long half life , so a Cannabis user may test positive for days and even weeks post use especially for chronic users and obese individuals. Police and work place may test drivers or workers, if they test positive, these individuals will admit to use of Cannabis days earlier and therefore they are not impaired. There is no test that shows when Cannabis was used, Courts will have a hell of a time convicting impaired drivers or workers secondary to Cannabis use. May God help us all. If your loved one gets killed or severely injured by an impaired user, the chance of that user getting convicted, for his crime, is very slim. It is a personal choice, to be a drug head (debatable),but it is a societal responsibility to protect its community at large from bad or dangerous personal choices..
