Unfortunately, no Canadian jurisdiction that we are aware of has systematically evaluated the effectiveness of their minimum pricing policies in reducing problem drinking, even though some have had these policies in place for many years.
The level at which a proposed minimum price should be set and the justification for that level
Although very little systematic research exists to address this question, the work of Murphy and MacKillop (2006)—which looks carefully at alcohol demand functions for college students in the US—suggests that prices above $1.50 (US) per standard drink begin to exert a downward influence on alcohol consumption by young adults.
We should restate that, based on our knowledge of published literature, there is no direct evidence anywhere in the world that minimum pricing policies are effective for reducing harmful drinking at the population level. What does exist are a number of studies from different disciplines which suggest that increasing minimum prices may be an effective way of addressing problem drinking.
