Background Exposure to stress is potentially important in the pathway to alcohol use and alcohol use disorders. Stressors occur at multiple time points across the life course, with varying degrees of chronicity and severity. Method We review evidence from epidemiologic studies on the relationship between four different stressors (fateful/catastrophic events, child maltreatment, common adult stressful life events in interpersonal, occupational, financial, and legal domains, and minority stress) and alcohol consumption and alcohol use disorders. Results Studies generally demonstrate an increase in alcohol consumption in response to exposure to terrorism or other disasters. Research has demonstrated little increase in incident alcohol use disorders, but individuals with a history of alcohol use disorders are more likely to report drinking to cope with the traumatic event. Childhood maltreatment is a consistent risk factor for early onset of drinking in adolescence and adult alcohol use disorders, and accumulating evidence suggests that specific polymorphisms may interact with child maltreatment to increase risk for alcohol consumption and disorder. Stressful life events such as divorce and job loss increase the risk of alcohol disorders, but epidemiologic consensus on the specificity of these associations across gender has not been reached. Finally, both perceptions of discrimination and objective indicators of discrimination are associated with alcohol use and alcohol use disorders among racial/ethnic and sexual minorities. Conclusion Taken together, these literatures demonstrate that exposure to stress is an important component in individual differences in risk for alcohol consumption and alcohol use disorders. However, many areas of this research remain to be studied, including greater attention to the role of various stressors in the course of alcohol use disorders and potential risk moderators when individuals are exposed to stressors.

This review provides an overview of the changing US epidemiology of cannabis use and associated problems. Adults and adolescents increasingly view cannabis as harmless, and some can use cannabis without harm. However, potential problems include harms from prenatal exposure and unintentional childhood exposure; decline in educational or occupational functioning after early adolescent use, and in adulthood, impaired driving and vehicle crashes; cannabis use disorders (CUD), cannabis withdrawal, and psychiatric comorbidity. Evidence suggests national increases in cannabis potency, prenatal and unintentional childhood exposure; and in adults, increased use, CUD, cannabis-related emergency room visits, and fatal vehicle crashes. Twenty-nine states have medical marijuana laws (MMLs) and of these, 8 have recreational marijuana laws (RMLs). Many studies indicate that MMLs or their specific provisions did not increase adolescent cannabis use. However, the more limited literature suggests that MMLs have led to increased cannabis potency, unintentional childhood exposures, adult cannabis use, and adult CUD. Ecological-level studies suggest that MMLs have led to substitution of cannabis for opioids, and also possibly for psychiatric medications. Much remains to be determined about cannabis trends and the role of MMLs and RMLs in these trends. The public, health professionals, and policy makers would benefit from education about the risks of cannabis use, the increases in such risks, and the role of marijuana laws in these increases.

Previous research suggests that various types of childhood maltreatment frequently co-occur and confer risk for multiple psychiatric diagnoses. This non-specific pattern of risk may mean that childhood maltreatment increases vulnerability to numerous specific psychiatric disorders through diverse, specific mechanisms or that childhood maltreatment engenders a generalised liability to dimensions of psychopathology. Although these competing explanations have different implications for intervention, they have never been evaluated empirically. We used a latent variable approach to estimate the associations of childhood maltreatment with underlying dimensions of internalising and externalising psychopathology and with specific disorders after accounting for the latent dimensions. We also examined gender differences in these associations. Data were drawn from a nationally representative survey of 34 653 US adults. Lifetime DSM-IV psychiatric disorders were assessed using the AUDADIS-IV. Physical, sexual and emotional abuse and neglect were assessed using validated measures. Analyses controlled for other childhood adversities and sociodemographics. The effects were fully mediated through the latent liability dimensions, with an impact on underlying liability levels to internalising and externalising psychopathology rather than specific psychiatric disorders. Important gender differences emerged with physical abuse associated only with externalising liability in men, and only with internalising liability in women. Neglect was not significantly associated with latent liability levels. The association between childhood maltreatment and common psychiatric disorders operates through latent liabilities to experience internalising and externalising psychopathology, indicating that the prevention of maltreatment may have a wide range of benefits in reducing the prevalence of many common mental disorders. Different forms of abuse have gender-specific consequences for the expression of internalising and externalising psychopathology, suggesting gender-specific aetiological pathways between maltreatment and psychopathology.

Objective The Department of Veterans Affairs’ (VA) electronic health records (EHR) offer a rich source of big data to study medical and health care questions, but patient eligibility and preferences may limit generalizability of findings. We therefore examined the representativeness of VA veterans by comparing veterans using VA healthcare services to those who do not. Methods We analyzed data on 3051 veteran participants age ≥ 18 years in the 2019 National Health Interview Survey. Weighted logistic regression was used to model participant characteristics, health conditions, pain, and self-reported health by past year VA healthcare use and generate predicted marginal prevalences, which were used to calculate Cohen’s d of group differences in absolute risk by past-year VA healthcare use. Results Among veterans, 30.4% had past-year VA healthcare use. Veterans with lower income and members of racial/ethnic minority groups were more likely to report past-year VA healthcare use. Health conditions overrepresented in past-year VA healthcare users included chronic medical conditions (80.6% vs. 69.4%, d = 0.36) , pain (78.9% vs. 65.9%; d  = 0.35), mental distress (11.6% vs. 5.9%; d  = 0.47), anxiety (10.8% vs. 4.1%; d  = 0.67), and fair/poor self-reported health (27.9% vs. 18.0%; d  = 0.40). Conclusions Heterogeneity in veteran sociodemographic and health characteristics was observed by past-year VA healthcare use. Researchers working with VA EHR data should consider how the patient selection process may relate to the exposures and outcomes under study. Statistical reweighting may be needed to generalize risk estimates from the VA EHR data to the overall veteran population.

Background. To examine sex differences in DSM-IV subclinical and pathological gambling in nationally representative data of the US population. Method. Data come from a large (n=43093) representative sample of the adult US population. Results. The lifetime prevalence rate of DSM-IV pathological gambling was 0·64% (95% CI 0·50–0·78) for men and 0·23% (95% CI 0·17–0·29) for women, whereas the lifetime prevalence of subclinical pathological gambling was 6·79% (95% CI 6·32–7·26) for men and 3·26% (95% CI 2·93–3·59) for women. For subclinical pathological gambling, men were significantly (p<0·01) more likely than women to have smoked more than two packs of cigarettes a day, to be classified as heavy drinkers and to have lifetime diagnoses of alcohol and drug use disorders. Women with subclinical and pathological gambling were significantly more likely than men to have lifetime mood and anxiety disorders. With respect to pathological gambling, women had later ages of onset of the disorder, and were significantly more likely than men to report gambling to relieve depressed mood and to prefer casino gambling. Rates of treatment-seeking for DSM-IV pathological gambling were low for both men and women. Conclusions. There are important sex differences in the prevalence, symptom pattern, sociodemographic and clinical correlates and course of DSM-IV subclinical and pathological gambling. Results underscore the need to investigate sex differences in the social determinants, neurobiology and treatment response of DSM-IV subclinical and pathological gambling.

The current study examined the relationship between acute (past 30 day) and recent (past year but not past 30 day) serious psychological distress (SPD) and smoking during pregnancy among women in the United States overall, stratified by demographic characteristics, and described the change in the prevalence of prenatal smoking among women with and without SPD, from 2008 to 2014. Data were drawn from the National Survey on Drug Use and Health (NSDUH), an annual cross-sectional study of US persons aged 12 and over. SPD and smoking in the past 30 days among pregnant women, aged 18 and older, were examined using logistic regression models. Heterogeneity in this association by demographic characteristics, trends over time, and level of cigarette consumption was also examined. Prenatal smoking was common. Almost 40% of pregnant women with acute SPD reported smoking, 23% of pregnant women with recent SPD smoked, and 11.7% of pregnant women without recent SPD smoked. No significant change was found in the prevalence of prenatal smoking from 2008 to 2014 in any of these groups. Robust relationships were found between acute (OR = 5.05 [3.64-6.99]) and recent SPD (OR = 2.37 [1.74-3.24]) and smoking; these findings remained after adjusting for demographics. SPD and smoking during pregnancy are strongly associated; this relationship is present across all sociodemographic groups and the prevalence of smoking in pregnancy has remained relatively unchanged over the past decade both in the presence and absence of SPD. SPD and smoking in pregnancy are robustly linked; the prevalence of smoking in pregnancy is extremely high in women with SPD. Screening women with mental health problems for prenatal smoking, as well as screening pregnant smokers for mental health problems, seems warranted and may assist more women in seeking and utilizing treatment options. Efforts to reduce the prevalence of smoking during pregnancy might specifically target women with SPD, where the potential for impact is substantial.

Background The Veterans Health Administration tracks urine drug tests (UDTs) among patients on long-term opioid therapy (LTOT) and recommends discussing the health effects of cannabis use. Objective To determine the occurrence of cannabis-related discussions between providers and patients on LTOT during six months following UDT positive for cannabis, and examine factors associated with documenting cannabis use. Design We identified patients prescribed LTOT with a UDT positive for cannabis in 2019. We developed a text-processing tool to extract discussions around cannabis use from their charts. Subjects Twelve thousand seventy patients were included. Chart review was conducted on a random sample of 1,946 patients. Main measures The presence of a cannabis term in the chart suggesting documented cannabis use or cannabis-related discussions. Content of those discussions was extracted in a subset of patients. Logistic regression was used to examine the association between patient factors, including state of residence legal status, with documentation of cannabis use. Key Results Among the 12,070 patients, 65.8% ( N  = 7,948) had a cannabis term, whereas 34.1% ( N  = 4,122) of patients lacked a cannabis term, suggesting that no documentation of cannabis use or discussion between provider and patient took place. Among the subset of patients who had a discussion documented, 47% related to cannabis use for medical reasons, 35% related to a discussion of VA policy or legal issues, and 17% related to a discussion specific to medical risks or harm reduction strategies. In adjusted analyses, residents of states with legalized recreational cannabis were less likely to have any cannabis-related discussion compared to patients in non-legal states [OR 0.73, 95% CI 0.64–0.82]. Conclusions One-third of LTOT patients did not have documentation of cannabis use in the chart in the 6 months following a positive UDT for cannabis. Discussions related to the medical risks of cannabis use or harm reduction strategies were uncommon.

Objectives. We investigated the modifying effect of state-level policies on the association between lesbian, gay, or bisexual status and the prevalence of psychiatric disorders. Methods. Data were from wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative study of noninstitutionalized US adults (N = 34 653). States were coded for policies extending protections against hate crimes and employment discrimination based on sexual orientation. Results. Compared with living in states with policies extending protections, living in states without these policies predicted a significantly stronger association between lesbian, gay, or bisexual status and psychiatric disorders in the past 12 months, including generalized anxiety disorder (F = 3.87; df = 2; P = .02), post-traumatic stress disorder (F = 3.42; df = 2; P = .04), and dysthymia (F = 5.20; df = 2; P = .02). Living in states with policies that did not extend protections also predicted a stronger relation between lesbian, gay, or bisexual status and psychiatric comorbidity (F = 2.47; df = 2; P = .04). Conclusions. State-level protective policies modify the effect of lesbian, gay, or bisexual status on psychiatric disorders. Policies that reduce discrimination against gays and lesbians are urgently needed to protect the health and well-being of this population.

Objectives. We examined the relation between living in states that instituted bans on same-sex marriage during the 2004 and 2005 elections and the prevalence of psychiatric morbidity among lesbian, gay, and bisexual (LGB) populations. Methods. We used data from wave 1 (2001–2002) and wave 2 (2004–2005) of the National Epidemiologic Survey on Alcohol and Related Conditions (N = 34 653), a longitudinal, nationally representative study of noninstitutionalized US adults. Results. Psychiatric disorders defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, increased significantly between waves 1 and 2 among LGB respondents living in states that banned gay marriage for the following outcomes: any mood disorder (36.6% increase), generalized anxiety disorder (248.2% increase), any alcohol use disorder (41.9% increase), and psychiatric comorbidity (36.3% increase). These psychiatric disorders did not increase significantly among LGB respondents living in states without constitutional amendments. Additionally, we found no evidence for increases of the same magnitude among heterosexuals living in states with constitutional amendments. Conclusions. Living in states with discriminatory policies may have pernicious consequences for the mental health of LGB populations. These findings lend scientific support to recent efforts to overturn these policies.

Heavy alcohol use is pervasive and one of our most significant global health burdens. Early theories posited that certain alcohol response phenotypes, notably low sensitivity to alcohol (‘low-level response’) imparts risk for alcohol use disorder (AUD). However, other theories, and newer measures of subjective alcohol responses, have challenged that contention and argued that high sensitivity to some alcohol effects are equally important for AUD risk. This study presents results of a unique longitudinal study in 294 young adult non-dependent drinkers examined with alcohol and placebo testing in the laboratory at initial enrolment and repeated 5 years later, with regular follow-up intervals assessing AUD (trial registration: http://clinicaltrials.gov/ct2/show/NCT00961792). Findings showed that alcohol sedation was negatively correlated with stimulation across the breath alcohol curve and at initial and re-examination testing. A higher rather than lower alcohol response phenotype was predictive of future AUD. The findings underscore a new understanding of factors increasing vulnerability to AUD.
