​Issues of Substance 2015: “Addiction Matters”

November 16-18, 2015
Hilton Montreal Bonaventure
900 Rue de la Gauchetière Ouest, Montréal QC

In 2015, IOS is delivered in partnership by the Canadian Centre on Substance Abuse and Mise sur toi.

Substance abuse and problem gambling are serious health concerns in Canada. Substance abuse alone costs our society more than $40 billion per year. Both disorders can ruin lives and remove from our communities those who would otherwise be capable of caring for their children, working, volunteering or studying. The good news is that addiction to alcohol, drugs and gambling is preventable and treatable, and recovery is an attainable reality for many. It is therefore paramount that these issues remain high priorities on the public agenda.

Addiction Matters. Together we can address it.
