Substance abuse is serious public health problem for which there are few effective pharmacotherapies. Traditional strategies for drug development have focused on antagonists to block the abuse-related effects of a drug at its site of action, and agonists to replace/mimic the effects of the abused substance. However, recent efforts have targeted receptors, such as serotonin (5-HT) receptors, that can indirectly modulate dopamine neurotransmission with the goal of developing a pharmacotherapy that might be effective at reducing the abuse-related effects of drugs more generally. Lorcaserin is a 5-HT receptor-preferring agonist that is approved by the US Food and Drug Administration for the treatment of obesity. Mounting evidence from preclinical and clinical studies suggests that lorcaserin might also be effective at reducing the abuse-related effects of drugs with different pharmacological mechanisms (e.g., cocaine, heroin, ethanol, and nicotine). Lorcaserin represents a promising and important first step towards the development a new class of pharmacotherapies that have the potential to dramatically improve the treatment of substance abuse. This article will review the behavioral pharmacology of 5-HT receptor-preferring agonists, with a focus on lorcaserin, and evaluate the preclinical evidence supporting the development of lorcaserin for treating substance abuse. This article is part of the Special Issue entitled 'Psychedelics: New Doors, Altered Perceptions'.

J Ethn Subst Abuse
January 2025
Arizona State University, Tempe, Arizona.
Unlabelled: The large majority (over 70%) of American Indian adolescents who reside in cities rather than tribal lands or rural areas report relatively earlier onset of substance use and more harmful associated health effects, compared to their non-Native peers.
Objective: This study investigated multilevel ecodevelopmental influences on empirically derived patterns of substance use among urban American Indian adolescents.
Method: Data came from 8th, 10th, and 12th grade American Indian adolescents ( = 2,407) in metropolitan areas of Arizona.
Athlete Selective Androgen Receptor Modulators Abuse: A Systematic Review.
Am J Sports Med
January 2025
Case Western Reserve University School of Medicine, Cleveland, Ohio, USA.
Background: Selective androgen receptor modulators (SARMs) are small-molecule compounds that exert agonist and antagonist effects on androgen receptors in a tissue-specific fashion. Because of their performance-enhancing implications, SARMs are increasingly abused by athletes. To date, SARMs have no Food and Drug Administration approved use, and recent case reports associate the use of SARMs with deleterious effects such as drug-induced liver injury, myocarditis, and tendon rupture.

Department of Psychiatry, McGill University, Douglas Hospital Research Center, Montreal, Quebec, Canada. Electronic address:
Objectives: Improving quality of care for individuals with substance-related disorders (SRD) should be a priority considering SRD are associated with high morbidity. This study aimed to identify classes of individuals with SRD based on their clinical characteristics and the quality of outpatient care they received, and to verify whether better quality of care was associated with other respondent characteristics and more favorable subsequent outcomes.
Methods: Data came from the 2023-14 and 2015-16 Canadian Community Health Survey (N = 42,099), merged with administrative data from Quebec's health insurance registry.
Availability of community resources reduces the association among community violence exposure, negative emotionality, and substance use disorders.

January 2025
Department of Psychology, Yale University, 100 College Street, New Haven, CT 06510, United States.
Background: Exposure to community violence is associated with increased occurrence of substance use disorders (SUD). The self-medication hypothesis states that heightened negative emotionality may underlie the link between exposure to community violence and SUD. However, it is not well-understood if access to community resources, a broader public health approach, influences the purported psychological mechanisms underlying the link between community violence exposure and SUD.
