Cannabis: A Round-up with Implications for Dental Practice
Dr. Jose Lança joined me for a round-up on the implications of legalizing cannabis in Canada. His presentation speaks to the broader implications of such substance and offers a wide range of considerations for Canadian dentists. Cannabis use and abuse will affect how dental treatment is dispensed and how dentists communicate with their patients about the potential risks of consuming recreational marijuana.
Dr. Lança is an assistant professor in the Faculty of Dentistry and the Faculty of Medicine at the University of Toronto. He is an expert with extensive research in the area of substance abuse.

- Studies show that the increased frequency of cannabis consumption during adolescence leads to a decrease in cognitive functioning, a decrease in educational and personal accomplishment, an increase in the risk of dependence and harm to developing adolescent brains, an increase in the rates of psychosis and other neuro-psychiatric disorders, particularly bipolar and anxiety disorders, and an increase in the risk of other substance abuse, namely alcohol, tobacco and opioids.
- Tests have shown that up to 5 nanograms of THC concentration per milliliter of blood constitute minor or moderate motor impairment. Five nanograms or higher constitute an offense that will be prosecuted either by indictment in serious cases or by summary conviction in less serious cases.
