As interest in the potential therapeutic benefits of cannabis-derived products grows, accurate predictors of abuse potential will be vital for informing regulatory decisions. Currently, the Food and Drug Administration recommends using subjective effect ratings of Drug Liking as the primary measure in human abuse potential studies. However, dissociations between subjective ratings and drug-taking behavior have been previously reported.

There is a concerning lack of published smoking cessation research on people with intellectual and developmental disabilities (IDD). A Functional Assessment for Smoking Treatment Recommendations (FASTR) was recently developed to help personalize patients' tobacco treatment. Adapting this tool to effectively identify putative environmental variables that maintain smoking for people with IDD is predicted to improve current treatments.

Introduction: Limited prospective research has evaluated the health benefits associated with changing levels of drug use, aside from complete abstinence. This study determined whether lower levels of cocaine use impacted physiological indices (e.g.

One of the most successful models of describing the decay in commodity consumption as a function of cost across multiple domains is the exponential model introduced by Hursh and Silberberg (2008). This model formulates the value of a commodity by including a "standardized price" adjustment. This adjustment allows for a theoretically scale-invariant parameter to estimate a normalized decay (α, the sensitivity to changes in price) in commodity consumption that was detangled from an organism's consumption when a commodity is free (₀).

Article Synopsis
  • This study examined how reducing cocaine use affects the immune system in individuals with Cocaine Use Disorder.
  • Participants were divided into three groups based on the value of financial rewards they received for abstaining from cocaine, with the highest rewards leading to the most significant reductions in use.
  • The findings indicated that the group receiving high rewards not only reduced cocaine use significantly but also showed changes in immune markers, indicating an activated immune response that could reflect improved immune health.

Contingency management is especially effective in supporting medication adherence and drug abstinence among people with opioid use disorder. However, the incorporation of contingency management into clinical practice has been slow. The present study was designed to evaluate the feasibility, acceptability, and usability of incentives for providers as a means of accelerating collaborative care with contingency management.

Disordered cannabis use is linked to social problems, which could be explained by a subjective devaluation of nondrug social contexts and/or an overvaluation of cannabis-paired options relative to nondrug alternatives. To examine these hypotheses, measures to assess the subjective value of social- and/or cannabis-paired contexts were collected in people who use cannabis ( = 85) and controls ( = 98) using crowdsourcing methods. Measures included a cued concurrent choice task that presented two images (cannabis, social, social cannabis, and neutral images) paired with monetary options, hypothetical purchase tasks that included access to social parties with and without a cannabis "open bar," and the Social Anhedonia Scale (SAS).

Background: Contingency Management (CM) is being piloted as a treatment for stimulant use disorder in several US states, highlighting the need for treatment optimization. One important goal of optimization is decreasing drug use during the early stages of treatment, which has predicted success in other interventions. However, this "critical period" has not been reported in CM trials.

Introduction: People with disabilities disproportionately use tobacco products. However, little is known about cessation interventions tailored for people with disabilities. The objective of this study was to conduct a systematic review of smoking cessation interventions for adults with disabilities.

Objectives: Despite a rich history of behavioral economic research on substance use there remains a need for further exploration of behavioral mechanisms that may underlie the etiology or persistence of substance use disorder. The purpose of this study was to measure the association between delay discounting and the endowment effect in people who smoke cigarettes, use cocaine, and controls, using online crowdsourcing.

Methods: Participants were categorized to a cocaine group (n = 36), cigarette group (n = 48), or control group (n = 47) based on recent reported drug use.

Buprenorphine is an important medication for treating opioid use disorder, but medication adherence and treatment retention are key issues that can limit its impact, especially when patients have concurrent stimulant use. Contingency management is efficacious in promoting medication adherence and drug abstinence. Delivering contingency management via smartphones addresses practical barriers to its adoption and improves patient access.

Introduction: People with disabilities have a higher prevalence of cigarette smoking than people without disabilities. However, little information exists on smoking cessation interventions tailored to address the unique needs of people with disabilities. This paper describes a systematic review protocol to identify and evaluate tobacco smoking cessation interventions designed to improve outcomes for people with disabilities.

The FDA has not yet approved a pharmacotherapy for cocaine use disorder despite nearly four decades of research. This study determined the initial efficacy, safety, and tolerability of naltrexone-bupropion combinations as a putative pharmacotherapy for cocaine use disorder. Thirty-one (31) non-treatment seeking participants with cocaine use disorder completed a mixed-design human laboratory study.

Contingency management (CM) interventions are based on operant principles and are effective in promoting health behaviors. Despite their success, a common criticism of CM is that its effects to not persist after the intervention is withdrawn. Many CM studies evaluate posttreatment effects, but few investigate procedures for promoting maintenance.

Contingency management (CM) interventions are the most effective psychosocial interventions for substance use disorders. However, further investigation is needed to create the most robust intervention possible. This study investigated the effects of 1) reinforcer magnitude; and 2) fixed and escalating and resetting incentives on cocaine abstinence in an outpatient trial.

The significant increase in opioid-related drug overdoses during the coronavirus disease (COVID-19) pandemic has put an unprecedented burden on hospital emergency departments, who saw as high as an approximate 150% increase in emergency department (ED) admission rates in the initial months of the pandemic. Although overdose is a clear sign of problem drug use, only a small proportion of nonfatal overdose patients enroll in treatment within 30 days of their overdose. To bridge the gap between opioid overdoses and treatment entry, a smartphone-smart debit card contingency management program was developed to promote entry into medication-assisted treatment by out-of-treatment opioid users who have recently received care in a hospital emergency department.

Article Synopsis
  • Cocaine use poses a significant public health challenge, necessitating a deeper understanding of how it affects the brain and behavior to improve prevention and intervention strategies.
  • A review of 41 human studies on cocaine self-administration highlights that drugs boosting extracellular dopamine consistently influence cocaine use; however, the effects of nondopaminergic drugs are less clear due to a lack of specific compounds for testing.
  • More research is essential to compare the impacts of acute versus chronic treatment and to explore different drug mechanisms to better understand how cocaine reinforcement works at a clinical level.
