Associations between compliance with very low nicotine content (VLNC) cigarettes, abstinence self-efficacy, and quit outcomes in a pilot smoking cessation trial.

Journal article Drug Alcohol Depend · September 1, 2024 BACKGROUND: Switching to Very Low Nicotine Content (VLNC) cigarettes reduces toxicant exposure and nicotine dependence, and may improve smoking cessation. However, non-compliance with VLNCs is often high, which may reduce their effectiveness. Here, we cond ... Full text Link to item Cite

Reactions to reduced nicotine content cigarettes in a sample of young adult, low-frequency smokers.

Journal article Psychopharmacology (Berl) · September 2021 RATIONALE: Reducing nicotine content in cigarettes to ≤ 2.4 mg per g of tobacco [mg/g] reduces smoking behavior and toxicant exposure among adult daily smokers.

ADHD, Smoking Withdrawal, and Inhibitory Control: Results of a Neuroimaging Study with Methylphenidate Challenge.

Journal article Neuropsychopharmacology · March 2018 Smoking withdrawal negatively impacts inhibitory control, and these effects are greater for smokers with preexisting attention problems, such as attention deficit/hyperactivity disorder (ADHD). The current study preliminarily evaluated changes in inhibitor ... Full text Link to item Cite

A Primer on Foraging and the Explore/Exploit Trade-Off for Psychiatry Research.

Journal article Neuropsychopharmacology · September 2017 Foraging is a fundamental behavior, and many types of animals appear to have solved foraging problems using a shared set of mechanisms. Perhaps the most common foraging problem is the choice between exploiting a familiar option for a known reward and explo ... Full text Link to item Cite

Smoking environment cues reduce ability to resist smoking as measured by a delay to smoking task.

Journal article Addict Behav · April 2017 INTRODUCTION: Environments associated with smoking may promote lapse and relapse in smokers attempting to quit. Here we examined the effects of exposure to visual smoking environment cues on smoking urge and the ability to resist smoking, as measured with ... Full text Link to item Cite

Association Between Baseline Corticothalamic-Mediated Inhibitory Control and Smoking Relapse Vulnerability.

Journal article JAMA Psychiatry · April 1, 2017 IMPORTANCE: Tobacco use disorder is associated with dysregulated neurocognitive function in the right inferior frontal gyrus (IFG)-one node in a corticothalamic inhibitory control (IC) network. OBJECTIVE: To examine associations between IC neural circuitry ... Full text Link to item Cite

Smoking Abstinence-Induced Changes in Resting State Functional Connectivity with Ventral Striatum Predict Lapse During a Quit Attempt.

Journal article Neuropsychopharmacology · September 2016 The ventral and dorsal striatum are critical substrates of reward processing and motivation and have been repeatedly linked to addictive disorders, including nicotine dependence. However, little is known about how functional connectivity between these and ... Full text Link to item Cite

The effects of nicotine and non-nicotine smoking factors on working memory and associated brain function.

Journal article Addict Biol · July 2016 Smoking abstinence impairs executive function, which may promote continued smoking behavior and relapse. The differential influence of nicotine and non-nicotine (i.e. sensory, motor) smoking factors and related neural substrates is not known. In a fully fa ... Full text Link to item Cite

Non-cigarette tobacco and poly-tobacco use among persons living with HIV drawn from a nationally representative sample.

Journal article Drug Alcohol Depend · May 1, 2016 INTRODUCTION: Smoking is more prevalent among persons living with HIV (PLWH) than the general population. Little is known about the prevalence of non-cigarette tobacco and poly-tobacco use (PTU; using multiple tobacco products) among this population, which ... Full text Link to item Cite

Blunted striatal response to monetary reward anticipation during smoking abstinence predicts lapse during a contingency-managed quit attempt.

Journal article Psychopharmacology (Berl) · March 2016 RATIONALE: Tobacco smoking is associated with dysregulated reward processing within the striatum, characterized by hypersensitivity to smoking rewards and hyposensitivity to non-smoking rewards. This bias toward smoking reward at the expense of alternative ... Full text Link to item Cite

Hippocampal and Insular Response to Smoking-Related Environments: Neuroimaging Evidence for Drug-Context Effects in Nicotine Dependence.

Journal article Neuropsychopharmacology · February 2016 Environments associated with prior drug use provoke craving and drug taking, and set the stage for lapse/relapse. Although the neurobehavioral bases of environment-induced drug taking have been investigated with animal models, the influence of drug-environ ... Full text Link to item Cite

"I Use Weed for My ADHD": A Qualitative Analysis of Online Forum Discussions on Cannabis Use and ADHD.
