The Science of Cannabis

Separate fact from fiction.

A collaborative program involving the Peter Boris Centre for Addictions Research, the Michael G. DeGroote Centre for Medicinal Cannabis Research, and McMaster Continuing Education

Enrol Now 

The legalization of marijuana is an enormous change for Canadians. The impact has had a cascading effect across many industries including: law enforcement, education, transportation, healthcare, pharmaceuticals, and legal services.

This shift in policy represents new opportunities for scientific research to help us understand how cannabis works and how it effects those who consume it. 

In partnership with the Peter Boris Centre for Addictions Research and the Michael G. DeGroote Centre for Medicinal Cannabis Research, McMaster is excited to announce ​one of the first evidence-based, post-secondary programs focused on "The Science of Cannabis."

The purpose of the program is to provide a substantive grounding in the scientific study of cannabis and the evidence base pertaining to its therapeutic applications as well as potential risks and harms.
