Large amounts of alcohol are produced globally that go unrecorded. Because this kind of alcohol is typically cheaper than licit alcohol, it may contribute to higher rates of heavy drinking. Link to Abstract

Association among different measures of alcohol use across adolescence and emerging adulthood

Among Canadian youth, two indices of alcohol use (heavy episodic drinking and overall quantity) are more strongly correlated with each other into early adulthood than other indices of alcohol use. These two indices also together account for greater variance in alcohol-related problems in emerging adulthood than either frequency or quantity alone. Link to Abstract
