Given the popularity and ease of single-item craving assessments, we developed a multi-item measure and compared it to common single-item assessments in an ecological momentary assessment (EMA) context. Two weeks of EMA data were collected from 48 emerging adults (56.25% female, 85.42% White) who frequently used cannabis. Eight craving items were administered, and multilevel factor analyses were used to identify the best fitting model. The resulting scale's factors represented purposefulness/general desire and emotionality/negative affect craving. Convergent validity was examined using measures of craving, cannabis use disorder symptoms, frequency of use, cannabis cue reactivity, cannabis use, negative affect, and impulsivity. The scale factors were associated with cue-reactivity craving, negative affect, impulsivity, and subfactors of existing craving measures. For researchers interested in using a single item to capture craving, one item performed particularly well. However, the new scale may provide a more nuanced assessment of mechanisms underlying craving.

Abnormalities of sphingolipid metabolism play an important role in diabetes. We compared sphingolipid levels in plasma and in isolated lipoproteins between healthy control subjects and two groups of patients, one with chronic kidney disease without diabetes (ND-CKD), and the other with type 2 diabetes and macroalbuminuria (D-MA). Ceramides, sphingomyelins, and sphingoid bases and their phosphates in LDL were higher in ND-CKD and in D-MA patients compared to controls. However, ceramides and sphingoid bases in HDL2 and HDL3 were lower in ND-CKD and in D-MA patients than in controls. Sphingomyelins in HDL2 and HDL3 were lower in D-MA patients than in controls but were normal in ND-CKD patients. Compared to controls, lactosylceramides in LDL and VLDL were higher in ND-CKD patients but not in D-MA patients. However, lactosylceramides in HDL2 and HDL3 were lower in both ND-CKD and D-MA patients than in controls. Plasma hexosylceramides in ND-CKD patients were increased and sphingoid bases decreased in both ND-CKD and D-MA patients. However, hexosylceramides in LDL, HDL2, and HDL3 were higher in ND-CKD patients than in controls. In D-MA patients, only C16:0 hexosylceramide in LDL was higher than in controls. The data suggest that sphingolipid measurement in lipoproteins, rather than in whole plasma, is crucial to decipher the role of sphingolipids in kidney disease.

INTRODUCTION: Females, versus males, have shown a slower decline in smoking prevalence, greater smoking-related mortality and morbidity, and tend to have more difficulty achieving and maintaining abstinence. Identifying sex-specific risk factors is needed to improve outcomes. Though ovarian hormones have been evaluated for their role in smoking and relapse, measures tend to be static and infrequent, failing to capture the influence of increasing or decreasing levels. AIMS AND METHODS: The present study evaluated the effect of static and fluctuating levels of ovarian hormones (ie, progesterone, estradiol, and estrogen to progesterone [E/P] ratio) on stress reactivity, cigarette craving, and smoking during a laboratory relapse paradigm. Female participants (assigned female at birth) reporting daily cigarette smoking (N = 91, ages 18-45) were recruited from the community. Participants provided daily salivary ovarian hormone levels leading up to a laboratory session, in which stress was induced and stress reactivity, cigarette craving, latency to smoke, and ad-libitum smoking were measured. RESULTS: Static levels of estradiol were associated with stress reactivity (ß = 0.28, SE = 0.13) and static E/P ratio was associated with smoking in the laboratory (HR = 1.4). Preceding 3-day changes in estradiol and E/P ratio, but neither static levels nor preceding 3-day changes in progesterone were associated with stress reactivity, cigarette craving, or smoking in a relapse paradigm. CONCLUSIONS: Ovarian hormones are among several sex-specific factors involved in the complex neuroendocrine response to stress, and their interaction with other biological, social, and psychological factors in the real-world environment is not yet fully understood. IMPLICATIONS: Findings of the present study provide novel information regarding the role of ovarian hormones among female participants who smoke daily in stress reactivity and smoking in the context of a laboratory relapse paradigm and highlight several avenues for future research. We found that same-day estradiol levels were associated with increased subjective stress reactivity and same-day estrogen to progesterone ratio was associated with increased likelihood of smoking in a relapse paradigm. Ovarian hormones are among several sex-specific factors contributing to the complex neuroendocrine response to stress, and their interaction with other biological, social, and psychological factors in the real-world environment is not yet fully understood.

Despite decades of progress, cigarette smoking remains a significant contributor to disease burden. This effect is especially pronounced for specific priority populations, such as individuals who live in rural communities, in that the burden of tobacco smoking is greater among these groups than in urban areas and the general population. The present study aims to evaluate the feasibility and acceptability of two novel tobacco treatment interventions delivered through remote telehealth procedures to individuals who smoke in the state of South Carolina. Results also include exploratory analyses of smoking cessation outcomes. Study I evaluated savoring, a strategy based on mindfulness practices, alongside nicotine replacement therapy (NRT). Study II evaluated retrieval-extinction training (RET), a memory-modification paradigm alongside NRT. In Study I (savoring), recruitment and retention data showed high interest and engagement in the intervention components, and participants who received this intervention decreased cigarette smoking throughout the course of the treatment (ps < .05). In Study II (RET), results showed high interest and moderate engagement in treatment, although exploratory outcome analyses did not demonstrate significant treatment effects on smoking behaviors. Overall, both studies showed promise in generating interest among individuals who smoke in participating in remotely delivered, telehealth smoking cessation interventions with novel therapeutic targets. A brief savoring intervention appeared to have effects on cigarette smoking throughout treatment, whereas RET did not. Gaining insight from the present pilot study, future studies may improve the efficacy of these procedures and incorporate the treatment components into more robust available treatments.

BACKGROUND: Cannabis use disorder (CUD) is a common and consequential disorder. When applied to the dorsolateral prefrontal cortex (DLPFC), repetitive transcranial magnetic stimulation (rTMS) reduces craving across substance use disorders and may have therapeutic clinical effects when applied in serial-sessions. The present study sought to preliminarily determine whether serial-sessions of rTMS applied to the DLPFC had a therapeutic effect in CUD. METHODS: This study was a two-site, phase-2, double-blind, randomized-controlled-trial. Seventy-two treatment-seeking participants (37.5% Women, mean age 30.2±9.9SD) with ≥moderate-CUD were randomized to active or sham rTMS (Beam-F3, 10Hz, 20-total-sessions, two-sessions-per-visit, two-visits-per-week, with cannabis cues) while undergoing a three-session motivational enhancement therapy intervention. The primary outcome was the change in craving between pre- and post- treatment (Marijuana Craving Questionnaire Short-Form-MCQ-SF). Secondary outcomes included the number of weeks of abstinence and the number of days-per-week of cannabis use during 4-weeks of follow-up. RESULTS: There were no significant differences in craving between conditions. Participants who received active-rTMS reported numerically, but not significantly, more weeks of abstinence in the follow-up period than those who received sham-rTMS (15.5%-Active; 9.3%-Sham; rate ratio = 1.66 [95% CI: 0.84, 3.28]; p=0.14). Participants who received active-rTMS reported fewer days-per-week of cannabis use over the final two-weeks of the follow-up period than those receiving sham-rTMS (Active vs. Sham: -0.72; Z=-2.33, p=0.02). CONCLUSIONS: This trial suggests rTMS is safe and feasible in individuals with CUD and may have a therapeutic effect on frequency of cannabis use, though further study is needed with additional rTMS-sessions and a longer follow-up period.

Timeline followback (TLFB) is often used in addiction research to monitor recent substance use, such as the number of abstinent days in the past week. TLFB data usually take the form of binomial counts that exhibit overdispersion and zero inflation. Motivated by a 12-week randomized trial evaluating the efficacy of varenicline tartrate for smoking cessation among adolescents, we propose a Bayesian zero-inflated beta-binomial model for the analysis of longitudinal, bounded TLFB data. The model comprises a mixture of a point mass that accounts for zero inflation and a beta-binomial distribution for the number of days abstinent in the past week. Because treatment effects appear to level off during the study, we introduce random changepoints for each study group to reflect group-specific changes in treatment efficacy over time. The model also includes fixed and random effects that capture group- and subject-level slopes before and after the changepoints. Using the model, we can accurately estimate the mean trend for each study group, test whether the groups experience changepoints simultaneously, and identify critical windows of treatment efficacy. For posterior computation, we propose an efficient Markov chain Monte Carlo algorithm that relies on easily sampled Gibbs and Metropolis-Hastings steps. Our application shows that the varenicline group has a short-term positive effect on abstinence that tapers off after week 9.

INTRODUCTION: This study sought to compare medication efficacy in participants with medical comorbidities who smoke in the Evaluating Adverse Events in a Global Smoking Cessation Study (EAGLES) trial, a double-blind, triple-dummy, placebo- and active-controlled randomized controlled trial. AIMS AND METHODS: Participants were from the U.S. cohort of the main trial and randomized (1:1:1:1) to varenicline, bupropion, nicotine replacement therapy (NRT) patch, or placebo for 12 weeks with follow-up through week 24. Medical comorbidity data were derived from the baseline medical screening questionnaire and categorized into four subgroups (cardiac, respiratory, vascular, and diabetes). Within each comorbidity, generalized linear mixed models were used to assess the association between treatment and continuous abstinence rates from weeks 9-12 to 9-24. Similar models were used to test the effect of number of comorbidities on abstinence. RESULTS: Varenicline resulted in the highest week 12 abstinence rates across all pharmacotherapies and compared to placebo in all comorbidity subgroups: Cardiac (40.0% vs. 3.6%; odds ratios [OR] = 23.3 [5.1-107.1]), respiratory (24.7% vs. 12.8%; OR = 2.2 [1.3-3.8]), vascular (29.1% vs. 10.4%; OR = 3.6 [2.3-5.7]), and diabetes (30.9% vs. 8.3%; OR = 6.5 [2.3-19.0]). This was maintained at week 24 for those with cardiac (23.3% vs. 1.8%; OR = 21.7 [2.7-178.2]), vascular (18.9% vs. 7.1%; OR = 3.1 [1.8-5.3]), and diabetes (20.6% vs. 4.2%; OR = 8.4 [2.1-33.7]) comorbidities. Treatment contrasts within some comorbidity subgroups revealed superior efficacy of varenicline over other pharmacotherapies. All pharmacotherapies increased the odds of abstinence regardless of number of comorbidities. CONCLUSIONS: Varenicline is the most efficacious option for patients with manageable cardiac, respiratory, vascular, and diabetes conditions to quit smoking, supporting recent clinical practice guidelines that recommend varenicline as first-line pharmacotherapy. Bupropion and NRT demonstrated efficacy for some comorbidity subgroups. IMPLICATIONS: This secondary analysis of the EAGLES trial demonstrated that varenicline is the most efficacious option for patients with cardiac, respiratory, vascular, and diabetes diagnoses to quit smoking. This demonstration of varenicline efficacy among individuals with comorbid medical conditions supports recent clinical practice guidelines that recommend varenicline as a first-line pharmacotherapy for smoking cessation.

Introduction: Functional magnetic resonance imaging (fMRI) studies examining cue-reactivity in cannabis use disorder (CUD) to date have either involved non-treatment seeking participants or been small. We addressed this gap by administering an fMRI cue-reactivity task to CUD participants entering two separate clinical trials. Methods: Treatment-seeking participants with moderate or severe CUD had behavioral craving measured at baseline via the Marijuana Craving Questionnaire (MCQ-SF). They additionally completed a visual cannabis cue-reactivity paradigm during fMRI following 24-hours of abstinence from cannabis. During fMRI, the Blood Oxygen Level Dependent (BOLD) signal was acquired while participants viewed cannabis-images or matched-neutral-images. BOLD responses were correlated with the MCQ-SF using a General Linear Model. Results: N=65 participants (32% female; mean age 30.4±9.9SD) averaged 46.3±15.5SD on the MCQ-SF. When contrasting cannabis-images vs. matched-neutral-images, participants showed greater BOLD response in bilateral ventromedial prefrontal, dorsolateral prefrontal, anterior cingulate, and visual cortices, as well as the striatum. Similarly, there was stronger task-based functional-connectivity (tbFC) between the medial prefrontal cortex and both the amygdala and the visual cortex. There were no significant differences in either activation or tbFC between studies or between sexes. Craving negatively correlated with BOLD response in the left ventral striatum (R 2 =-0.25; p =0.01). Conclusions: We found that, among two separate treatment-seeking CUD groups, cannabis cue-reactivity was evidenced by greater activation and tbFC in regions related to executive function and reward processing, and craving was negatively associated with cue-reactivity in the ventral striatum. Future directions include examining if pharmacological, neuromodulatory, or psychosocial interventions can alter corticostriatal cue-reactivity.

Cannabis use disorder (CUD) presents differently in men and women, particularly in symptoms of cannabis withdrawal. Novel pharmacotherapeutic interventions for CUD, such as those that target the endocannabinoid (eCB) system, must be developed in a manner consistent with these sex differences. The present pilot study sought to prospectively assess sex differences in cannabis withdrawal in a small sample of adults with moderate-to-severe CUD and to determine if withdrawal was associated with peripheral eCB and eCB congener tone. Men and women (n = 5/sex) completed 2 weeks of study participation separated by 1 month; in the latter week, participants abstained from cannabis use. Each week, participants attended in-person laboratory visits during which blood was drawn repeatedly to assess plasma eCB and eCB congener tone. Participants also completed multiple daily ambulatory assessments to assess cannabis use and withdrawal symptoms. As anticipated, women reported a greater increase in withdrawal symptoms during the abstinent week [Δ = 9.4 (SE = 1.1); p < 0.001] than men [Δ = 1.2 (SE = 1.2); p = 0.35]. Sex differences in levels of the eCB N-arachidonoylethanolamide (AEA), as well as the eCB congeners stearoylethanolamide (SEA) and linoleylethanolamide (LEA), were evident during abstinence at the morning time point only (p's < 0.05). LEA was associated with withdrawal symptom expression in both sexes [ß = 0.16 (SE = 0.09)] and palmitoylethanolamide (PEA) [ß = 0.22 (SE = 0.13)] and 2-arachidonoylglycerol (2-AG) [ß = 0.32 (SE = 0.15)] were associated with withdrawal symptoms in women only. Pharmacotherapeutic development for CUD should consider evident sex differences in eCB and eCB congener tone during abstinence and their associations with cannabis withdrawal, as eCB-based interventions may produce differential effects by sex.

BACKGROUND: Technological advancements to study young adult smoking, relapse, and to deliver interventions remotely offer conceptual appeal, but the incorporation of technological enhancement must demonstrate benefit over traditional methods without adversely affecting outcomes. Further, integrating remote biochemical verification of smoking and abstinence may yield value in the confirmation of self-reported smoking, in addition to ecologically valid, real-time assessments. OBJECTIVE: The goal of this study was to evaluate the impact of remote biochemical verification on 24-hour self-reported smoking and biochemical verification agreement, retention, compliance with remote sessions, and abstinence during a brief, 5-week cessation attempt and relapse monitoring phase. METHODS: Participants (N=39; aged 18-25 years; mean age 21.6, SD 2.1 years; n=22, 56% male; n=29, 74% White) who smoked cigarettes daily engaged in a 5-week cessation and monitoring study (including a 48-hour quit attempt and provision of tobacco treatment in the form of nicotine replacement therapy, brief cessation counseling, and financial incentives for abstinence during the 2-day quit attempt only). Smoking (cigarettes per day) was self-reported through ecological momentary assessment (EMA) procedures, and participants were randomized to either (1) the inclusion of remote biochemical verification (EMA + remote carbon monoxide [rCO]) 2× per day or (2) in-person, weekly CO (wCO). Groups were compared on the following outcomes: (1) agreement in self-reported smoking and breath carbon monoxide (CO) at common study time points, (2) EMA session compliance, (3) retention in study procedures, and (4) abstinence from smoking during the 2-day quit attempt and at the end of the 5-week study. RESULTS: No significant differences were demonstrated between the rCO group and the wCO (weekly in-person study visit) group on agreement between 24-hour self-reported smoking and breath CO (moderate to poor), compliance with remote sessions, or retention, though these outcomes numerically favored the wCO group. Abstinence was numerically higher in the wCO group after the 2-day quit attempt and significantly different at the end of treatment (day 35), favoring the wCO group. CONCLUSIONS: Though study results should be interpreted with caution given the small sample size, findings suggest that the inclusion of rCO breath added to EMA compared to EMA with weekly, in-person CO collection in young adults did not yield benefit and may have even adversely affected outcomes. Our results suggest that technological advancements may improve data accuracy through objective measurement but may also introduce barriers and burdens and could result in higher rates of missing data. The inclusion of technology to inform smoking cessation research and intervention delivery among young adults should consider (1) the research question and necessity of biochemical verification and then (2) how to seamlessly incorporate monitoring into personalized and dynamic systems to avoid the added burden and detrimental effects to compliance and honesty in self-report.

BACKGROUND: Hedonic dysregulation is a core mechanism of addiction. There is a dearth of research on hedonic dysregulation in cannabis use disorder (CUD). The current study tested whether personalized scripted imagery may be an efficacious approach to remediate reward functioning in adults with CUD. METHODS: Adults with CUD (n=10) and non-CUD controls (n=12) completed a single session personalized scripted imagery procedure. Non-drug (i.e. natural) reward and neutral scripts were transcribed and participants listened to the scripts in counterbalanced order. Primary outcomes included positive affect (PA), galvanic skin response (GSR), and cortisol and were assessed at four timepoints. Mixed effects models were used to compare between and within subject effects. RESULTS: Mixed effects models revealed a Condition (reward vs. neutral) X Group (CUD vs. control) interaction (p=0.01) on PA response, indicating blunted PA response to the neutral script relative to the reward script in CUD participants. Likewise, GSR response in CUD participants was decreased in response to the neutral script relative to the reward script (p=0.034; interaction n.s.). An interaction effect of Group X PA on cortisol response was found (p=.036) indicating that cortisol was positively correlated with PA in healthy control participants, but not CUD participants. CONCLUSIONS: Adults with CUD may demonstrate acute deficits in hedonic tone under neutral conditions relative to healthy controls. Personalized scripted imagery may be an efficacious tool to remediate hedonic dysregulation in CUD. Cortisol may play a role in healthy positive affect regulation warranting further investigation.

BACKGROUND: Complementary integrative medicine, such as mindfulness-based interventions, (MBI) have demonstrated efficacy in the treatment of depression, anxiety, substance use disorders (SUDs), and pain. Mindfulness-based relapse prevention (MBRP) is an aftercare intervention targeting SUD relapse that integrates cognitive-behavioral relapse prevention and mindfulness meditation practices, raising awareness of substance use triggers and reactive behavioral patterns. This study evaluated the efficacy of MBRP in reducing relapse in veterans following completion of an SUD treatment program. METHODS: This study was a two-site, randomized controlled trial comparing MBRP to 12-step facilitation (TSF) aftercare in military veterans following completion of intensive treatment for SUDs. The 8 weeks of 90-minute, group-based MBRP or TSF sessions were followed by 3-, 6- and 10-month follow-up periods with assessments of alcohol/substance use and secondary outcomes of depression, anxiety, and mindfulness. RESULTS: Forty-seven percent of veterans attended ≥75 % of sessions. Veterans in both the MBRP and TSF aftercare groups maintained reductions in alcohol and illicit substance use during the aftercare treatment. Nineteen participants (11 %; 19/174) reported returning to alcohol use during the study treatment period and the study found no difference between study groups [MBRP: 9 % vs. TSF 13 %; p = 0.42]. Thirteen participants (7.5 %; 13/174) reported a return to illicit substance use during study treatment [MBRP: 5.4 % vs. TSF 10.3 % p = 0.34]. The number of days of drinking and illicit substance use was not different between groups (alcohol, p = 0.53; illicit substance use, p = 0.28). CONCLUSION: Although retention in treatment limits interpretation of the findings, both MBRP and TSF were effective in maintenance of treatment gains following an intensive treatment program for veterans with SUDs. Future studies should focus on strategies to improve treatment participation.

Despite high rates of Post-Traumatic Stress Disorder (PTSD) in persons living with HIV (PLWH) and poor HIV-related health outcomes associated with PTSD, an effective evidence-based treatment for PTSD symptoms in PLWH does not exist. Negative reinforcement conceptual models posit that avoidant behavior (hallmark symptom of PTSD) demonstrated by PLWH with co-occurring PTSD can contribute to poor antiretroviral therapy (ART) adherence. However, research evaluating the impact of evidence-based treatment for PTSD among HIV infected populations on HIV outcomes is scarce. The Cognitive Processing Therapy (CPT) protocol is an evidence-based PTSD treatment that may address internalized stigma with targeted modifications and improve ART adherence and subsequent viral suppression through reduction of avoidant coping. This study will be the first pilot open-label randomized control trial (RCT) to test feasibility of an integrated evidence-based PTSD treatment (CPT) with an adherence intervention (Lifesteps) delivered in a Ryan White clinic to improve PTSD symptoms, adherence to ART, and retention in HIV care. Primary aims are to (1) conduct theater testing of the CPT and Lifesteps research protocol and evaluate acceptability (n = 12) and (2) deliver a modified CPT protocol (CPT-Lifesteps, or CPT-L) in 60 PLWH/PTSD exploring impact of CPT-L on PTSD symptoms and HIV outcomes compared to a Lifesteps + Standard of Care condition. This innovative research extends PTSD treatment approaches as a paradigm to reduce barriers to ART adherence. Findings of this innovative study are significant because they support the Undetectable = Untransmittable (U[bond, double bond]U) campaign and can help prevent the transmission of HIV infection through increased viral suppression.

BACKGROUND: Understanding the relationship between tobacco use and symptom burden may inform tobacco treatment interventions tailored to the needs of individuals with cancer. METHODS: The study included 1409 adult cancer survivors from Wave 5 of the US Food and Drug Administration Population Assessment of Tobacco and Health (PATH) Study. A multivariate analysis of variance controlling for age, sex, and race/ethnicity assessed the association of cigarette smoking and vaping on cancer-related symptom burden (fatigue, pain, emotional problems) and quality of life (QoL). Generalized linear mixed models controlling for the same factors were used to assess associations among symptom burden, QoL, and quit-smoking intentions, quit-smoking likelihood, and past 12-month smoking quit attempts. RESULTS: Weighted rates of current cigarette smoking and vaping were 14.21% and 2.88%, respectively. Current smoking was associated with greater fatigue (p < .0001; partial η 2  = .02), pain (p < .0001; partial η 2  = .08), emotional problems (p < .0001; partial η 2  = .02), and worse QoL (p < .0001; partial η 2  = .08). Current vaping was associated with greater fatigue (p = .001; partial η 2  = .008), pain (p = .009; partial η 2  = .005), and emotional problems (p = .04; partial η 2  = .003), but not worse QoL (p = .17). Higher cancer symptom burden was not associated with reduced interest in quitting, likelihood of quitting, or odds of past year quit attempts (p > .05 for each). CONCLUSIONS: Among adults with cancer, current smoking and vaping were associated with greater symptom burden. Survivors' interest in and intentions to quit smoking were not related to symptom burden. Future research should examine the role of tobacco cessation in improving symptom burden and QoL.

INTRODUCTION: Contingency management (CM) interventions deliver monetary reinforcers contingent upon biochemically verified abstinence from smoking. CM has been found to be effective, however, individual participant, analyses are warranted to further elucidate how individual-level behavior patterns vary during the intervention period, both within and across treatment groups. AIMS AND METHODS: This is a secondary analysis of a randomized controlled pilot trial of presurgical cancer patients who smoke (RCT N = 40). All participants were current everyday smokers and were enrolled in cessation counseling, offered nicotine replacement therapy, and submitted breath CO testing 3 times per week for 2-5 weeks. Participants randomized to CM received monetary reinforcers for breath CO ≤6 ppm on an escalating schedule of reinforcement with a reset for positive samples. Sufficient breath CO data exist for 28 participants (CM = 14; monitoring only [MO] = 14). Effect size was calculated for differences in negative CO tests. Time to first negative test was tested using survival analysis. Fisher's exact test was used to assess relapse. RESULTS: The CM group achieved abstinence more quickly (p < .05), had a lower percentage of positive tests (h = 0.80), and experienced fewer lapses following abstinence (p = .00). While 11 of 14 participants in the CM group achieved and sustained abstinence by their third breath test, this was only true for 2 of the 14 MO participants. CONCLUSIONS: Those in CM achieved abstinence quicker and with fewer lapses than those engaged in MO speaking to the efficacy of the schedule of financial reinforcement. This is particularly important within presurgical populations given the potential benefits to postoperative cardiovascular and wound infection risk. IMPLICATIONS: While the efficacy of CM as an intervention is well established, this secondary analysis provides insight into the individual behavior patterns underlying successful abstinence. Those assigned to CM were not only more likely to achieve abstinence, but did so more quickly and with fewer instances of relapse. This is of particular importance to those scheduled for surgery where achieving abstinence as early as possible impacts on the risk of postoperative complications. CM interventions may be particularly well suited for critical windows in which timely and sustained abstinence is advantageous.

Background: Adverse childhood experiences (ACEs) show a graded association with the development of substance use disorders (SUDs) and engagement in risky substance use behaviors. Women are overrepresented among individuals with more severe childhood adversity (≥4 types of ACEs) and may be at particular risk for aberrant substance use.Objectives: To assess the prevalence of ACEs among men and women with cannabis, opioid, cocaine, and tobacco use disorders.Methods: Non-treatment-seeking individuals participating in clinical addiction research at a single site completed the ACE questionnaire and provided a detailed substance use history. Data were analyzed using proportional odds models and logistic regression.Results: Most participants (424/565; 75%) reported at least one ACE, and more than one-quarter (156/565; 27%) reported severe childhood adversity. Relative to men (n = 283), women (n = 282) reported more ACEs (OR = 1.49; p = .01) and more experiences of emotional/physical abuse (OR = 1.52; p = .02), sexual abuse (OR = 4.08; p = .04), and neglect (OR = 2.30; p < .01). Participants in the cocaine (OR = 1.87; n = .01) and opioid (OR = 2.21; p = .01) use disorder, but not cannabis use disorder (OR = 1.46; p = .08), studies reported more severe adversity relative to the tobacco group. Relative to tobacco users, emotional/physical abuse (OR = 1.92; p = .02) and neglect (OR = 2.46; p = .01) scores were higher in cocaine users and household dysfunction scores were higher in opioid users (OR = 2.67; p = .01).Conclusion: The prevalence of ACEs differs with respect to both participant gender and primary substance used. Novel SUD treatment strategies that incorporate ACEs may be uniquely beneficial in specific subpopulations of people with SUDs.

INTRODUCTION: Primary care visits present an opportune time to assess behaviors that contribute to patient health. Smoking, alcohol use, and illicit drugs are routinely documented in electronic health records, but less is known about screening for E-cigarette use and the prevalence of E-cigarette use in primary care settings. METHODS: Data include 134,931 adult patients who visited 1 of 41 primary care clinics within a 12-month period (June 1, 2021-June 1, 2022). Data on demographics, combustible tobacco, alcohol, illicit drug, and E-cigarette use were extracted from electronic medical records. Logistic regression was utilized to examine the variables associated with differential odds of being screened for E-cigarette use. RESULTS: Rates of E-cigarette screening (n=46,997; 34.8%) were significantly lower than that of tobacco (n=134,196; 99.5%), alcohol (n=129,766; 96.2%), and illicit drug (n=129,766; 92.6%) use. Of those assessed for E-cigarette use, 3.6% (n=1,669) reported current use. Of those with documented nicotine use (n=7,032), 17.2% (n=1,207) used mono E-cigarettes exclusively, 76.3% (n=5,364) used combustible tobacco exclusively, and 6.6% (n=461) reported dual use (both E-cigarette use and combustible tobacco use). Those who used combustible tobacco or illicit substances as well as younger patients were more likely to have been screened for E-cigarette use. CONCLUSIONS: Overall rates of E-cigarette screening were significantly lower than those of other substances. The use of combustible tobacco or illicit substances was associated with an increased likelihood of being screened. This finding may be because of the relatively recent proliferation of E-cigarettes, the recent addition of E-cigarette documentation to the electronic health record, or a lack of training on screening for E-cigarette use.
