Featured Project

The ‘Lower-Risk Cannabis Use Guidelines’ (LRCUG) is an evidence-based, targeted prevention tool aiming to reduce the risks for health harm among individuals using cannabis. The project was originally conceived in 2010; the most recently updated version of the LRCUG was developed by a multi-national team of scientific experts and published in 2020. The LRCUG have produced multiple ‘knowledge translation’ products for consumers and professionals, and have been utilized by leading substance use, health and governmental entities in Canada and abroad.
