Glucagon-like peptide-1 receptor agonists and risk of substance use disorders among US veterans with type 2 diabetes: cohort study

The BMJ

This study investigated whether initiation of glucagon-like peptide-1 (GLP-1) receptor agonists is associated with both reduced risks of incident alcohol, cannabis, cocaine, nicotine, opioid, and other substance use disorders (SUDs) in people with no history of SUDs (protocol 1) and with reduced risk of SUD-related adverse clinical outcomes among people with a pre-existing SUDs (protocol 2). Researchers found that use of GLP-1 receptor agonists was consistently associated with reduced risks of developing various incident SUDs, suggesting a broad preventive effect across multiple substance types. Use was also associated with reduced risks of adverse clinical outcomes in people with pre-existing SUDs. These observational data suggest a potential role for GLP-1 receptor agonists in both the prevention and treatment of various SUDs, warranting further evaluation.

Does the total consumption model apply to cannabis use?

Addiction

This repeated cross-sectional study based on annual surveys tested whether the total consumption model and its extension, the theory of collectivity, apply to adolescent cannabis use in Sweden. Frequency of cannabis use was measured by a question on how many occasions the respondent has used hashish or marijuana. The seven response alternatives ranged from 0 to 50 times or more. Increases in mean frequency use were associated with a higher prevalence of high-frequency users. Adolescent cannabis use in Sweden appears to conform to key predictions of the total consumption model and its extension, the theory of collectivity.

Spirituality and Harmful or Hazardous Alcohol and Other Drug Use

JAMA Psychiatry

This meta-analysis of 55 rigorous studies on spirituality and harmful or hazardous drug use (alcohol, tobacco, marijuana, or illicit drugs) examined the association between spiritual exposures and related drug use outcomes. It documented a significant protective association of 13% related to both prevention and recovery. The risk reduction, which extended across all 4 drug categories, reached 18% for individuals with greater than weekly religious service attendance. These results have implications for clinicians and communities regarding future strategies to address harmful or hazardous alcohol or other drug use.
