Cannabis

Guide to information and research about cannabis use and health post-legalization.


Purpose of this Guide

In order to support the information needs of health care providers, researchers, policy makers involved in delivering and improving health services, and the general community, this resource guide was developed through a partnership between Dalhousie University Libraries and Nova Scotia Health Authority Library Services. The focus of this Guide is on reliable information pertaining to cannabis use and health. It is not possible to cover all relevant topics on the Guide in depth. If you are looking for more information, please contact us and we will be happy to help.

Medicinal vs. Recreational Use

We acknowledge that legalization of cannabis has health and social impacts. When experiencing these impacts, it is important to consider that the body of scientific evidence about the use of cannabis has been impacted by its status as illegal. A large proportion of the scientific evidence to date examines the potential harm cannabis may cause (e.g. Eggertson, 2017). This guide recognizes that while there is a place for harm-focused research, there is also a need to explore the therapeutic role of cannabis and anticipates that research with this focus will increase over time.
