Objective: Withdrawal syndrome stands out as the strongest risk factor for Prescription Opioid-Use Disorder (POUD) and is related to psychological and pain impairment in chronic pain population. This study aimed to identify profiles of chronic pain patients with opioid withdrawal based on psychological factors, and to explore the association between the classes and demographic, clinical, and substance use variables.

Method: This cross-sectional descriptive study involved 391 patients, 221 of them with interdose withdrawal (mean age=57.91±13.61 years; 68.3% female). Latent Class Analysis (LCA) and bivariate and logistic regression analyses were performed.

Results: Two latent classes were identified (BIC=4020.72, entropy=0.70, LRTs p<0.01): Withdrawal syndrome with No Psychological Distress (WNPD; 45.2%, n=100) and Withdrawal syndrome with Psychological Distress (WPD; 54.8%, n=121). The WPD class was more likely to experience craving, anxiety, and depression, and to report higher levels of pain intensity and interference (p<0.01). Patients in this class were younger, visited a higher number of specialists, and showed higher rates of high-dose opioid use, misuse, moderate-severe POUD, and tobacco and anxiolytics use (p<0.05). Only moderate-severe POUD (OR=2.64) and tobacco use (OR=2.28) increased the risk of WPD class membership.

Conclusions: Although it is common for chronic pain patients to experience withdrawal symptoms during opioid treatment, more than a half of the participants reported concomitant psychological distress. Establishing differential profiles can help to improve withdrawal syndrome management during the treatment of chronic pain with opioids.

Objective: Previous research has demonstrated different cannabis-related outcomes depending on the goal of cannabis use (i.e., recreational, medical, hybrid of both), underscoring the need to identify variables associated with specific goals of use, particularly in understudied populations.

Method: This report utilized data from a national survey of menopausal individuals using non-probability sampling. Respondents reporting current regular (≥1x/month) cannabis use (medical n=35, recreational n=61, and hybrid n=102) were included in multivariate logistic regression analyses examining demographic, clinical (e.g., menopause-related symptomatology), and cannabis-related variables associated with goal of cannabis use.

Results: Overall, increased number of medical conditions was associated with medical and hybrid use relative to recreational use (ps≤.047), and greater menopause-related symptomatology was associated with medical relative to hybrid use (p=.001). Lower education level was associated with hybrid relative to recreational use (p=.010). Lastly, increased number of modes of use was associated with hybrid use relative to medical and recreational use (ps≤.001).

Conclusions: Results suggest medical and hybrid consumers with more medical conditions and more severe clinical symptoms that are not sufficiently alleviated by conventional treatments may be more open to cannabinoid-based therapies. Additionally, as lower education level is often associated with recreational cannabis use, results suggest hybrid consumers may begin as recreational consumers who then expand their use for medical purposes. Further, more varied modes of use for hybrid consumers may reflect different product selection based on goal of use. Future research should investigate the etiology of hybrid cannabis use and predictors of long-term outcomes associated with goals of use.

Objective: Prevention programs that address the intersecting health problems of risky alcohol use, unsafe sexual behaviors, and sexual violence are needed. This pilot project assessed the feasibility, acceptability, and preliminary efficacy of a two-session group-based intervention, Sex Positive Lifestyles: Addressing Alcohol & Sexual Health (SPLASH), targeting these highly interconnected risks for college students across genders.

Method: A total of 217 participants (51.6% male, ages 18-24) took part in the SPLASH intervention or a nutrition/exercise control condition. SPLASH included three approaches aimed at reducing the incidence of alcohol problems, unsafe sex, and sexual victimization: normative feedback to modify misperceptions around peers' drinking, sexual behaviors, and support of bystander intervention; drinking and sexual-related protective behavioral strategy training to enhance safer drinking and sex-risk behaviors; and bystander intervention skills training to promote bystander efficacy and engagement. Participants completed baseline and follow-up (1-month and 6-month) online assessments.

Results: SPLASH demonstrated high acceptability and feasibility, as well as preliminary efficacy. SPLASH participants reported strong acceptability of the intervention, particularly its integrated content and interactive, in-person group format. Successful enrollment (70% randomized) and retainment point to the feasibility of recruiting students to this two-session in-person intervention. Results showed sustained trends toward more accurate perceived sex-related norms and indications of increasing bystander norms among intervention but not control participants.

Conclusions: Results demonstrate the potential for SPLASH to effectively address the interrelated health risks of risky alcohol use, unsafe sex, and sexual violence on college campuses and point to the need for larger-scale studies.

Objective: People who use both alcohol and combustible tobacco have an increased risk of developing cancer. Few interventions have been developed to inform people about the risks of co-use. This study developed and tested messages about the risks of alcohol and combustible tobacco co-use among adults.

Method: In June-July 2021, we surveyed 1,300 U.S. adults who used both alcohol and combustible tobacco products within the past 30 days. After reporting their awareness of diseases caused by tobacco and alcohol co-use, participants were randomly assigned to four between-subjects experiments that manipulated specific cancer health effects vs. the word "cancer"; cancer health effects vs. noncancer health effects; different descriptions of co-use (e.g., Using alcohol and tobacco…, Drinking alcohol and smoking tobacco…); and co-use vs. single-use messages. Participants saw one message for each experiment and rated each message using a validated perceived message effectiveness (PME) scale.

Results: Awareness of health effects caused by alcohol and tobacco co-use ranged from moderately high for throat cancer (65.4%) to moderately low for colorectal cancer (23.1%). Messages about cancer health effects increased PME more than messages about non-cancer health effects (B=0.18, p=0.01). Messages about some specific cancers-including oral cancer (B=-0.20, p=0.04) and colorectal cancer (B=-0.22, p=0.02) decreased PME more than messages with only the word "cancer." No significant differences were identified for descriptions of co-use or co-use vs. single-use messages.

Conclusions: Messages about some cancer health effects of co-using alcohol and tobacco may be effective when communicating the harms of both drinking alcohol and using tobacco.

Objective: To study the prevalence of alcohol use among French adolescents over time and factors associated with heavy episodic drinking (HED) among drinkers.

Method: Our analysis relies on six waves of a standardized cross, sectional survey conducted in mainland France between 2005 and 2022. The overall sample size comprises 179905 adolescents aged 17 (90166 males and 89739 females). Two outcomes were considered: declaring past month HED (at least one) and repeated HED (at least three) in the past month between 2005 and 2022. Relative risks and probabilities according to years of survey, gender and frequency of alcohol use (past 30 days) were estimated using modified Poisson regressions controlling for grade retention, schooling, living out of parental household, socioeconomic status, and other substance (tobacco, cannabis, other illicit substances) use.

Results: Despite a steady decline in alcohol use among French adolescents over the past two decades, the prevalence of HED still concerned one, third of 17-year-olds in 2022. The reduction in alcohol use conceals an increased likelihood of HED among occasional drinkers (<10 times a month). Moreover, the probability of HED among females is similar to that of males, or even higher depending on the frequency of use.

Conclusions: HED is becoming an increasingly common behavior among adolescent drinkers. The decline in prevalence conceals a homogenization of behavior between genders. Our results also question underage access to alcohol, despite increasing legal restrictions. These results support general prevention in early adolescence aimed at all drinkers, and not only at the most frequent or "at-risk" drinkers.

Objective: There is considerable variability in how young adults (YAs) perceive drinking-related consequences, and some researcher-identified "negative" consequences are viewed by YAs as neutral or even somewhat positive. Little is known about individual difference factors that may influence subjective evaluations of alcohol consequences.

Method: We tested whether endorsement and subjective evaluation ('extremely negative' to 'extremely positive') of 24 alcohol-related "negative" consequences differed by age (18-20, 21-27), past 3-month drinking frequency (3x/month or less, weekly or more), and current undergraduate status (4-year undergraduate, non-student). YAs were recruited for a longitudinal ecological momentary assessment study on cognitions and alcohol use. Participants in the analytic sample (N=640; 48.1% White non-Hispanic/Latinx, 50.0% female, mean age=22.2 years, SD=2.3) reported past 3-month drinking. Past 3-month drinking frequency, negative consequences (total and item-level), and subjective evaluations of consequences were assessed cross-sectionally.

Results: Compared to YAs 18-20, YAs 21+ experienced fewer total consequences, were significantly less likely to endorse experiencing physical/behavioral consequences, and rated these consequences more negatively if they were endorsed. YAs who drank weekly or more reported experiencing more consequences and were significantly more likely to experience all 24 consequences in comparison to YAs who drank 3x/month or less. Subjective evaluation ratings did not significantly differ by drinking frequency. There were few differences between 4-year undergraduate and non-undergraduates; non-undergraduates rated several health/responsibility-related consequences more negatively.

Conclusions: Findings highlight the importance of identifying individual difference factors that contribute to subjective evaluation ratings, and may be useful for tailoring brief, personalized alcohol interventions for YAs.

Objective: Ellagic acid (EA) exerts, neuroprotective, mitoprotective, anti-oxidative and anti-inflammatory effects. We evaluated protective effect of EA on ethanol-induced fetal alcohol spectrum disorders (FASD).

Methods: A total of 35 newborn male rats were used, divided into five groups, including; control (normal saline), ethanol (5.25 g/kg per day), ethanol (5.25 g/kg per day) + EA (10 mg/kg), ethanol (5.25 g/kg per day) + EA (20 mg/kg) and ethanol (5.25 g/kg per day) + EA (40 mg/kg). Thirty-six days after birth behavioral tests (Morris water maze and Elevated Plus Maze), tumor necrosis factor-α (TNF-α) levels, oxidative markers (malondialdehyde, glutathione and superoxide dismutase), mitochondrial examination such as succinate dehydrogenases (SDH) activity, mitochondrial swelling, mitochondrial membrane potential (MMP) and reactive oxygen species (ROS) formation were analyzed.

Results: The results revealed that ethanol exposure adversely affected cognitive and mitochondrial functions and as well as induced oxidative stress and inflammation in brain tissue. However, EA (20 and 40 mg/kg) administration effectively prevented the toxic effects of ethanol in FASD model.

Conclusions: These findings demonstrate that ethanol application significantly impairs the brain development via mitochondrial dysfunction and induction of oxidative stress. These data indicate that EA might be a useful compound for prevention of alcohol-induced FASD.

Objective: Little is known about the consequences of substance-related advertising on driving under the influence of alcohol (DUIA) or cannabis (DUIC). This study seeks to estimate associations between substance-related digital advertising exposures and DUIA and DUIC in a sample of young adults.

Method: The Rhode Island Young Adult Survey 2022 was a cross-sectional web-based survey of 1,022 adults ages 18-25 years. Analyses were conducted among lifetime alcohol users (n = 824) and lifetime cannabis users (n = 471). Prevalence of past-30-day digital ad exposure to alcohol and cannabis was assessed, as well as the prevalence of past-month DUIA and DUIC. Multivariable logistic regressions examined the association between digital ad exposure and substance use among lifetime users, and ad exposure and DUI among current users.

Results: In all, 54.4% of participants reported past-30-day exposure to digital alcohol advertising, and 33.5% reported exposure to digital cannabis advertising. Exposure to social media alcohol advertising was associated with higher odds of DUIA after adjustment for sociodemographic variables (odds ratio [95% CI] = 2.14 [1.07, 4.28]) but not after accounting for frequency of use. Odds of DUIC remained significantly higher for those exposed to app-based cannabis advertising after adjusting for sociodemographic variables (odds ratio [95% CI] = 4.36 [1.76, 10.8]) and frequency of use (odds ratio [95% CI] = 3.96 [1.53, 10.2]).

Conclusions: Since social media alcohol ad exposure may be indirectly linked with DUIA, and app-based cannabis ad exposure may be directly linked to frequency of use and DUIC, legislators should consider comprehensive substance-related ad regulations and bans.

Objective: Most research on alcohol control policies in the United States has focused on the state level. In this study, we assessed both local and state policy prevalence and restrictiveness in a nationwide sample of cities.

Method: We conducted original legal research to assess prevalence of local-level policies across 374 cities (48 states) in 2019 for the following seven policy areas: (a) drink specials; (b) beverage service training; (c) minimum age for on-premise servers and bartenders; (d) minimum age for off-premise sellers; (e) prohibitions against hosting underage drinking parties (i.e., social host provisions); (f) bans on off-premise Sunday sales; and (g) keg registration. We obtained parallel state-level policies from the Alcohol Policy Information System. We assessed the restrictiveness of existing policies and how these compared across local and state levels.

Results: We found that for six of the seven policy areas, the majority of cities (53% to 83%) had only a state-level policy. Few cities (0% to 8% across policy areas) had only a local-level policy. The percentage of cities that had an alcohol policy at both the local and state levels ranged from less than 1% to 19% across policy areas, and the policies were mostly equally restrictive at both levels.

Conclusions: The lack of local policies may point to areas where these localities could strengthen their alcohol policy environments. Additional research is needed to understand how the prevalence and restrictiveness of local and state policies are associated with public health harms such as traffic crashes.
