DSM-IV and DSM-5 alcohol use disorder among young Swiss men

Previous studies suggest the new DSM-5 criteria for alcohol use disorder (AUD) will increase the apparent prevalence of AUD. However, in a high-risk sample of young Swiss males, prevalence of AUD as diagnosed by DSM-5 was slightly lower than prevalence of DSM-IV diagnosis of dependence plus abuse. Link to Abstract

In the United States, the density of alcohol outlets in a county is positively correlated with alcohol-related suicide, especially among American Indians/Alaska Natives. Link to Abstract

Alcohol in the second half of life: do usual quantity and frequency of drinking to intoxication increase with increased drinking frequency?

Among Norwegian adults in the second half of life, increased drinking frequency appears to be associated with a small reduction in usual quantity, and a small increase in frequency of drinking to intoxication. Link to Abstract

High-frequency drug purity and price series as tools for explaining drug trends and harms in Victoria, Australia

Decreases in methamphetamine purity-adjusted price along with the bimodality of crystal methamphetamine purity may account for some of the recent increase in methamphetamine-related harm in Victoria, Australia. For a given amount spent, methamphetamine purchase power has increased and the presence of extreme purity variations may challenge individuals' control of consumption. Link to Abstract
