Special Issue Information

Dear Colleagues,

This Special Issue seeks original research on effective treatment strategies promoting emotional and cognitive-behavioral health, as well as healthy coping mechanisms, to improve care and outcomes for people living with addiction.

Life experiences such as adverse childhood experiences can trigger emotions that prompt coping responses that may include substance use. Psychoactive substances negatively impact the limbic system and the amygdala, influencing emotional processing and resulting in a vicious cycle of use, abuse and disorder. Mindfulness training plays a prominent role in the prevention and treatment of substance use disorders. Individuals with substance use disorders struggle with cognitive flexibility and inhibitory control, impairing their ability to adapt and resist cravings. Chronic substance use alters brain regions like the prefrontal cortex and hippocampus, causing long-term cognitive dysfunction. Interventions, such as cognitive-behavioral therapy and neurorehabilitation, can address these deficits and improve recovery outcomes.

Understanding how people develop and maintain substance use is increasingly guided by research on behavior, responses to rewards, stress and cues in their environment. Cognitive-behavioral therapy involves coping skills, decision-making and healthy behaviors shown to reduce substance use and support long-term recovery. These three dimensions play a pivotal role in understanding and providing evidence-based treatment in the fields of Psychiatry/Psychology.

This Special Issue will complement the existing literature by integrating emotional, cognitive and behavioral perspectives that are often studied in isolation. Although substantial research has examined each domain’s role in substance use disorders, fewer efforts have synthesized these dimensions to clarify how they collectively influence addiction trajectories and treatment outcomes. By highlighting work that spans neurobiological mechanisms, clinical interventions and applied coping strategies, this issue aims to provide a more unified, evidence-based framework to inform future research and clinical practice.

Marijuana use in the United States (U.S.) has diversified alongside expanding legalization, yet little is known about the psychosocial factors that distinguish medical from recreational use. This study examined whether psychological distress mediates the association between perceived social isolation (i.e., loneliness) and marijuana use type among U.S. adults. We analyzed cross-sectional, nationally representative data from the 2024 Health Information National Trends Survey (HINTS, cycle 7). Marijuana use was categorized as medical (including medical and both medical/recreational) versus recreational. Perceived social isolation was measured using the Patient-Reported Outcomes Measurement Information System (PROMIS) Social Isolation t-score, and psychological distress was assessed with the Personal Health Questionnaire (PHQ)-4. Survey-weighted descriptive analyses and a weighted structural equation mediation model accounting for the complex sampling design were conducted. Medical marijuana users reported significantly higher levels of psychological distress and perceived social isolation than recreational users. Greater social isolation was strongly associated with higher psychological distress, and higher distress was associated with a greater likelihood of medical (vs. recreational) marijuana use. The indirect effect of social isolation on marijuana use type through psychological distress was statistically significant, while the direct effect of social isolation was not significant after accounting for distress. Overall, greater perceived social isolation predicted medical marijuana use primarily through elevated psychological distress. These findings suggest that medical marijuana use among U.S. adults may reflect coping with psychological distress linked to social disconnection, underscoring the importance of integrating mental health and social context into clinical and public health approaches to cannabis use.
