Changes in weight among individuals with psychiatric conditions or socioeconomic disadvantage assigned to smoke very low nicotine content cigarettes.
Experimental and Clinical Psychopharmacology, Vol 32(2), Apr 2024, 181-188; doi:10.1037/pha0000700Nicotine abstinence leads to weight gain, which could be an unintended consequence of a nicotine reduction policy. This secondary analysis used weekly assessments of weight and ratings of “increased appetite/hunger/weight gain” collected in three 12-week, randomized controlled trials evaluating the effects of cigarettes differing in nicotine dose (15.8, 2.4, or 0.4 mg/g) among individuals with affective disorders, opioid use disorder (OUD), and socioeconomically disadvantaged women. Linear mixed models tested differences b...

Randomized trial assessing the effect of the JUUL system on switching away from cigarettes and smoking reduction among U.S. adults who smoke cigarettes.
This study assessed switch rates and smoking reduction among participants randomized to use JUUL in a choice of flavors or tobacco-only, compared to a condition provided smoking-cessation materials. U.S. adults who smoke cigarettes (N = 837; Mage [SD] = 45.99 years [11.48]; 18.76 cigarettes/day [SD = 7.86]; 50.2% female) from an address-based representative panel were randomized to receive JUUL for 6 months (5.0% nicotine; only Virginia Tobacco [N = 285] or choice of flavors [N = 281]), or smoking-cessation materials (quit advice [QA]; N = 271). Self-reported past 30-day smoking and cigarette consumption were assessed at 1...

A novel abuse liability assessment of e-cigarettes in young adults ii: Reinforcement enhancement and follow-up assessment.
Experimental and Clinical Psychopharmacology, Vol 32(2), Apr 2024, 173-180; doi:10.1037/pha0000687A double-blind study was performed to test the abuse liability of electronic nicotine delivery systems (ENDS) in young adults; in particular, the influence of nicotine on reward sensitivity was assessed. A total of 53 healthy nonusers participated in experimental sessions during which they played a video game made available on a progressive ratio schedule of reinforcement and self-administered nicotine via ENDS. Participants were randomized into one of three groups. Two groups received either a dedicated concentration of nicot...

Signal processing and machine learning with transdermal alcohol concentration to predict natural environment alcohol consumption.
Experimental and Clinical Psychopharmacology, Vol 32(2), Apr 2024, 245-254; doi:10.1037/pha0000683Wrist-worn alcohol biosensors continuously and discreetly record transdermal alcohol concentration (TAC) and may allow alcohol researchers to monitor alcohol consumption in participants’ natural environments. However, the field lacks established methods for signal processing and detecting alcohol events using these devices. We developed software that streamlines analysis of raw data (TAC, temperature, and motion) from a wrist-worn alcohol biosensor (BACtrack Skyn) through a signal processing and machine learning pipeline: bi...

Alcohol demand in college students: The roles of athletic involvement and gender.
Experimental and Clinical Psychopharmacology, Vol 32(1), Feb 2024, 54-67; doi:10.1037/pha0000681College student-athletes represent a high-risk group for heavy alcohol consumption and negative alcohol-related consequences. Although college drinking correlates with access to low-cost alcohol, no study has examined demand, or the relationship between price and consumption, in student-athletes. Furthermore, the prevalence of anxiety, depression, and drinking to cope motives in student-athletes suggest athlete-specific risks of alcohol consumption that have not yet been examined in conjunction with demand. Therefore, the presen...

Stereotype threat contributes to poorer recall performance among undergraduate students with problematic drinking patterns.
Experimental and Clinical Psychopharmacology, Vol 32(2), Apr 2024, 236-244; doi:10.1037/pha0000680Stereotype threat occurs when individuals from stigmatized groups feel they are expected to conform to a negative stereotype associated with their group. Studies show that activating stereotype threat can impair performance on cognitive tasks in various marginalized groups. Individuals with problematic alcohol use are subject to stigmatized views related to cognitive abilities and socialization skills; thus, we examine for the first time whether eliciting stereotype threat impairs performance on a memory and a theory of mind t...

Mixed amphetamine salts–extended release (MAS-ER) as a behavioral treatment augmentation strategy for cocaine use disorder: A randomized clinical trial.
Experimental and Clinical Psychopharmacology, Vol 32(1), Feb 2024, 112-127; doi:10.1037/pha0000676Psychosocial interventions remain the primary strategy for addressing cocaine use disorder (CUD), although many individuals do not benefit from these approaches. Amphetamine-based interventions have shown significant promise and may improve outcomes among individuals continuing to use cocaine in the context of behavioral interventions. One hundred forty-five adults (122 males) who used cocaine a minimum of 4 days in the prior month and met the criteria for a CUD enrolled in a two-stage intervention. All participants received a...

The association between exercise and prescription opioid misuse: A scoping review.
Experimental and Clinical Psychopharmacology, Vol 32(2), Apr 2024, 140-149; doi:10.1037/pha0000675Exercise prevents chronic diseases and modulates pain. People experiencing pain often use opioids for relief, increasing the risk of prescription opioid misuse. Nonetheless, exercise may influence prescription opioid misuse through the release of endorphins or induced injury-related pain. We aimed to summarize the existing literature on the association between exercise and prescription opioid misuse. We identified studies published through December 2021 in Cochrane, Embase, Medline, and Pubmed, using search terms like “opioi...

Cocaine and heroin interact differently with nondrug reinforcers in a choice situation.
Experimental and Clinical Psychopharmacology, Vol 32(2), Apr 2024, 158-172; doi:10.1037/pha0000674The present study used a rat choice model to test how cocaine or heroin economically interacted with two different nondrug reinforcers along the substitute-to-complement continuum. In Experiment 1, the nondrug alternative was the negative reinforcer timeout-from-avoidance (TOA)—that is, rats could press a lever to obtain a period of safety from footshock. One group of rats chose between cocaine and TOA and another group chose between heroin and TOA. The relative prices of the reinforcers were manipulated across phases while ...

Nicotine deprivation amplifies attentional bias toward racial discrimination stimuli in African American adults who smoke cigarettes.
Experimental and Clinical Psychopharmacology, Vol 31(6), Dec 2023, 1023-1031; doi:10.1037/pha0000662High smoking prevalence and low quit smoking rates among African American adults are well-documented, but poorly understood. We tested a transdisciplinary theoretical model of psychopharmacological–social mechanisms underlying smoking among African American adults. This model proposes that nicotine’s acute attention-filtering effects may enhance smoking’s addictiveness in populations unduly exposed to discrimination, like African American adults, because nicotine reduces the extent to which discrimination-related stimu...

Combustible cigarette smokers versus e-cigarette dual users among Latinx individuals: Differences in alcohol and drug use severity.
Experimental and Clinical Psychopharmacology, Vol 32(2), Apr 2024, 197-206; doi:10.1037/pha0000673The Latinx population in the United States (U.S.) experiences significant tobacco and other substance use-related health disparities. Yet, little is known about the couse of combustible cigarettes and e-cigarettes (dual use) in relation to substance use behavior among Latinx smokers. The present investigation compared English-speaking Latinx adults living in the United States who exclusively smoke combustible cigarettes versus dual users in terms of alcohol use and other drug use problem severity. Participants were 297 Hispani...
