  • Engaging Sexual and Gender Minority Cigarette Smokers Into Social Media-based Treatment

    open to eligible people ages 18 years and up

    This research study will evaluate the preliminary efficacy of Pride Posts Plus, a social media-based smoking cessation treatment. A pilot randomized trial (N=120) will compare Pride Posts Plus, which includes a gamification element, to Pride Posts (without gamification) and to a usual care treatment. Participants will be adults who smoke, identify as sexual or gender minorities, and use Facebook. The primary outcome will be biochemically verified 7-day abstinence from smoking at 3 and 6 months. Secondary outcomes will be treatment engagement, a quit attempt (y/n), and thoughts about tobacco abstinence at 3 and 6 mos.

  • Impact of Very Low Nicotine Content Cigarettes in a Complex Marketplace

    open to eligible people ages 21 years and up

    This project will examine the impact of very low nicotine content (VLNC) cigarettes in a complex tobacco and nicotine product marketplace. We will compare the number of cigarettes smoked and cigarette-free days in an experimental marketplace that contains VLNC cigarettes versus normal nicotine content (NNC) cigarettes.

  • Novel Pharmacotherapy Approaches in Smokers With Serious Mental Illness

    open to eligible people ages 18-70

    Approximately 60 chronic smokers with bipolar disorder, schizophrenia or schizoaffective disorder who are motivated to try to quit smoking will be randomized to receive smoking cessation treatment with the FDA-approved medication, varenicline, delivered either a) at its standard dose and titration schedule (half of the participants) versus b) at a lower dose and slower titration schedule (the other half), for 12 weeks. All smokers will choose a target quit date sometime between 8 to 35 days after starting the medication. All participants will receive ten 30-minute sessions of a behavioral treatment called Acceptance and Commitment Therapy (ACT). Participants will be followed for an additional 12 weeks off study medication. The major endpoint is the feasibility of combining ACT with the different dosing strategies. Investigators will also conduct a blood test that measures the breakdown of nicotine in the body to explore whether that measure influences treatment response and side effects.

  • Short-Term Cardiovascular Effects of E-Cigarettes: Influence of Device Power

    open to eligible people ages 21 years and up

    This study will examine the short-term cardiovascular (CV) effects of e-cigarette device power in a randomized, crossover clinical and behavioral pharmacology study of experienced adult e-cigarette users (N=21). The specific aim is to determine the impact of e-cigarette power on nicotine pharmacology, systemic exposure to toxic volatile organic compounds (VOCs), and short-term cardiovascular effects.

  • Text Messaging to Engage and Retain Veterans in Smoking Cessation Counseling

    open to eligible people ages 18 years and up

    Tobacco-related diseases account for a significant portion of all VA healthcare costs and are a detriment to the health and quality of life of our Veterans. Despite progress in instituting tobacco screenings and treatment referral, most Veterans still do not receive the most effective strategy to help them quit smoking - pharmacotherapy combined with behavioral coaching. This study builds on findings from population health and mobile interventions to help more Veterans receive evidence-based tobacco treatment. The investigators propose to test the effect of two types of text messaging in combination with telephone cessation counseling: 1) pre-counseling text messages to increase enrollment in counseling, and 2) ongoing texts for those who start counseling that provide appointment reminders and support between sessions to increase adherence to counseling. This study supports multiple goals of the VA's Blueprint for Excellence. Results will directly inform decision-making and population-based care models for tobacco treatment.

  • Cigarette Harm Reduction With Electronic Cigarette Use

    Sorry, not yet accepting patients

    This is an observational, crossover study that will be examine use behaviors, chemical exposures, and biological effects of SREC compared to TC use in subjects confined to a research ward setting.

  • Short-Term Cardiovascular Effects of E-Cigarettes: Influence of E-Liquid pH

    Sorry, not yet accepting patients

    This study will examine the short-term cardiovascular (CV) effects of e-liquid pH in a randomized, crossover clinical and behavioral pharmacology study of experienced adult e-cigarette users (N=21). The specific aim of the study is to assess the impact of changes in e-liquid pH on nicotine pharmacokinetics, cardiovascular, and subjective effects of e-cigarettes.

  • THC Crossover Study

    Sorry, not yet accepting patients

    This is a randomized, crossover study enrolling experienced dual cannabis-tobacco smokers (N=18) to describe the differences in THC and toxicant exposure, examining pharmacokinetic, subjective, and cardiovascular effects from smoking and vaping dry herb cannabis. This study will also examine the differences in toxicant exposure and cardiovascular disease risk between smoking cannabis and smoking tobacco cigarettes.

  • Vaping High vs. Low Nicotine E-Liquid

    Sorry, not yet accepting patients

    This study will examine the effects of electronic cigarette e-liquid nicotine content in a randomized, crossover clinical and behavioral pharmacology study of experienced adult e-cigarette users (N=36). The specific aim is to determine the impact of nicotine content of e-liquid on nicotine pharmacology, systemic exposure to toxic volatile organic compounds, and short-term cardiovascular effects.
