Biopsychosocial Factors of Cannabis Use: A Narrative Review on Nutrition, Emotions and Environment

Fernando Hernández-Leonardo, Alma Gabriela Martínez-Moreno — Wed, 30 Sep 2026 00:00:00 -0500

Introduction: cannabis use has increased globally, driving extensive research into its effects; however, debate persists regarding its therapeutic potential versus its adverse health consequences.

Objective: to analyze the relationship between cannabis consumption and biopsychosocial factors, focusing on its impact on eating behavior, gastrointestinal health, emotional states, and the sociocultural context.

Method: a narrative review was conducted using electronic searches in PubMed and Google Scholar (2000–2025 period). Controlled vocabulary (MeSH/DeCS) and Boolean operators were combined, focusing on the endocannabinoid system, eating behavior, digestive disorders, parenting styles, emotions, and social stigma. Forty-seven scientific articles meeting eligibility and conceptual relevance criteria were selected, followed by an integrative qualitative thematic synthesis.

Results: cannabis modulates appetite and food sensory perception via CB1 receptor activation; nonetheless, chronic consumption is associated with digestive disorders. Psychologically, permissive and neglectful parenting styles correlate with a heightened risk of consumption, with psychological outcomes encompassing potential anxiolytic properties and, under specific contexts, psychotic symptoms. Within the social dimension, stigma and legal frameworks condition risk perception and clinical reporting.

Discussion and conclusions: the biopsychosocial model demonstrates that the effects of cannabis cannot be reduced to isolated pharmacological determinism. This comprehensive framework provides the groundwork to design tailored preventive strategies, guide clinical decision-making, and inform evidence-based regulatory public policies.

Caring with Humanity in Times of Addictions: A Challenge for Nursing

Ursula Elisa Elias Bravo — Fri, 04 Sep 2026 00:00:00 -0500

In the current context of addiction, nursing practice is often developed within a care-oriented framework, focused on administering treatments and managing disordered behaviors. This dynamic, while necessary, risks relegating the essence of care: humanization and the therapeutic relationship. This article aims to critically analyze the role of nursing in the care of people with addictions, highlighting the importance of humanized care in highly vulnerable contexts.

Introduction: not much is known about video game addiction in Peru, particularly in internet café users, who may have greater engagement with video games and therefore a higher risk of developing this disorder.

Objective: the present study aimed to examine the relationship between problematic video game use (PVG), basic psychological needs, and passion in young adults who frequent internet cafés in Metropolitan Lima.

Method: the sample consisted of 133 young adults who visit internet cafés specialized in video games located in a shopping mall (M = 23.74 years, SD = 4.58, 83.5% male). The study used the short version of the Internet Gaming Disorder Scale (IGDS9-SF), the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS), and the Passion Scale. A mediation model was tested regarding the influence of passion on the association between basic psychological needs satisfaction and frustration and PVG.

Results: results show that obsessive passion has a mediating effect on the indirect impact of autonomy frustration and competence frustration on PVG.

Discussion and conclusions: the findings suggest that the frustration of certain basic psychological needs may lead to PVG, and if the person also develops an obsessive passion toward games, a maladaptive usage pattern may emerge.

Family Structure and Substance Use among Mexican Adolescents: The Mediating Role of Parental Monitoring Styles

Introduction: family structure and parental monitoring styles have been identified as relevant factors associated with adolescent substance use.

Objective: to examine the associations among family structure, parental monitoring styles, and substance use among Mexican adolescents, as well as to evaluate the mediating role of parental monitoring using structural equation modeling.

Method: a cross-sectional study was conducted with a non-probabilistic sample of 3,572 upper secondary school students from eleven Mexican cities. Structural equation modeling was used to analyze the direct and indirect relationships among family structure, parental monitoring styles, and substance use. Family structure was recoded into dummy variables using nuclear families as the reference category.

Results: adolescents from single-parent, reconstituted, and extended families reported lower levels of parental rule-setting (β = -.25, β = -.41, and β = -.52, respectively) and parental supervision (β = -.37, β = -.40, and β = -.76, respectively). Only single-parent families showed a significant association with higher levels of parental coldness-rejection (β = .27, p < .001). Parental supervision was negatively associated with both licit (β = -.03) and illicit substance use (β = -.03), whereas parental coldness–rejection was positively associated with licit (β = .02) and illicit substance use (β = .01). Indirect effects suggested a partial mediating role of parental monitoring in the association between family structure and adolescent substance use.

Discussion and conclusions: the findings highlight that specific parental monitoring styles are significantly associated with adolescent substance use. These results underscore the importance of family-based prevention strategies aimed at promoting consistent supervision, clear rule-setting, and positive parent-adolescent relationships.

Association between Mental Health and the Use of Electronic Cigarettes and other Drugs among Mexican University Students

Tue, 06 Oct 2026 00:00:00 -0500

Introduction: in Mexico, the use of drugs and electronic cigarettes (e-cigarettes) has increased considerably, with the university population showing the highest prevalence. Despite being a current issue, there are few studies that simultaneously evaluate mental health, mental well-being, and the consumption of drugs and e-cigarettes in Mexican university students are scarce.

Objective: to analyze the association between mental health and the use of drugs and e-cigarettes in Mexican university students.

Method: a cross-sectional, correlational study was conducted with a sample of 422 university students. Instruments included the drug use frequency item from the ASSIST v3.1 test, the Global Adult Tobacco Survey (GATS), the Depression, Anxiety and Stress Scale (DASS-21), and the Warwick–Edinburgh Mental Well-being Scale (WEMWBS).

Results: tobacco and e-cigarette use were associated with stress, depression, and anxiety; alcohol use was associated with stress and mental well-being; cannabis use was associated with stress; cocaine use was associated with stress, depression, and mental well-being; stimulant use was associated solely with mental well-being; and the use of sedatives and other drugs was associated with stress, depression, anxiety subscales, and mental well-being. Having used e-cigarettes at least once predicted higher scores for stress, anxiety, and depression, whereas current daily use was associated with lower mental well-being.

Discussion and conclusions: the findings support the need to develop strategies for the prevention, detection, and treatment of substance use behaviors, particularly among young adults and in higher education settings.
