Issues of Substance (IOS) is Canada's premier educational event for the substance abuse field. Organized by the Canadian Centre on Substance Abuse, IOS focuses on new approaches to making a collective impact on substance abuse problems in Canada. It is held every two years in November to complement National Addictions Awareness Week.
The theme and venue for IOS 2015 is still under careful consideration.
