  • Electronic Hookah and Endothelial Cell Function

    open to eligible people ages 21-39

    Electronic nicotine delivery systems (ENDS) are a new rapidly growing global epidemic. More recently, electronic (e-) hookahs, have increased in popularity in the United States, with the greatest uptake by young female adults, who endorse marketing claims that these products are safer alternatives to traditional flavored hookah tobacco smoking. Unlike other ENDS such as e-cigarettes, e-hookah bowls are used through traditional water-pipes, allowing the vapor-containing nicotine, propylene glycol, glycerin, and flavorings-to pass through a water-filled basin, potentially altering the vapor, before it is inhaled through the user's mouth. Contributing to e-hookah bowls' popularity is the belief that the flavored smoke is detoxified as it passes through the water-filled basin, rendering e-hookah a safer tobacco alternative. However, an e-hookah bowl delivers flavored nicotine by creating a vapor of fine particles and volatile organic compounds that could induce vascular toxicity. The objective of this project is to investigate the effects of e-hookah bowl inhalation on endothelial function, vascular biomarkers and volatile compounds; and molecular mechanisms underlying e-hookah induced endothelial injury using freshly harvested human endothelial cells with a specific role of nicotine. In a cross-over study design, the investigators will first assess endothelial function measured by brachial artery flow-mediated dilation and markers of oxidative stress and inflammation in 18 young healthy hookah smokers 21-39 years old, before and after two separate 30-minute e-hookah bowl inhalation sessions using one brand of nicotine-containing and nicotine-free e-hookah liquid and, for control comparison, before and after sham hookah smoking. Then, in freshly harvested venous endothelial cells the investigators will assess nitric oxide bioavailability, and expression of markers of inflammation and oxidative stress before and after the sessions. To compare specific exposures across conditions, the research team will measure changes in plasma nicotine, and highly specific urinary mercapturic acid metabolites of acrolein and benzene. This proposed study will provide critical scientific data on the impact of e-hookah inhalation on vascular health and mechanisms of exposure on known cardiac risk factors. Results will provide critical data to the FDA to inform the development of regulations specific to hookah.

  • Empower Korean Families to End Tobacco Use & Smoking Exposure

    open to eligible people ages 18 years and up

    The goals of the study are to develop a culturally and linguistically appropriate intervention to promote smoking cessation and reduce secondhand smoke exposure for Korean Americans using a family-based intervention approach targeting Korean Americans ages 18 and above in the greater San Francisco Bay Area, CA, and to evaluate efficacy of the proposed intervention. The study is a randomized control trial targeting a total of 8 lay health workers (LHW) and 48 dyads of a daily smoker and a partner who will attend intervention sessions together. The research question is: Can a family-based lay health worker outreach intervention promote smoking cessation and reduce SHS exposure among Korean Americans?

  • Investigating the Cardiovascular Toxicity of Exposure to Electronic Hookah Vaping

    open to eligible people ages 21-39

    Hookah (water-pipe) smoking has quickly grown to become a major global tobacco epidemic among youth; with electronic hookahs more recently increasing in popularity especially among young female adults, who endorse marketing claims that these products are a safer alternative to traditional hookah, but scientific evidence is lacking. The study aims to elucidate the comparative effects of traditional hookah smoking vs. electronic hookah inhalation on human vascular and endothelial function; and examine the role of inflammation and oxidative stress as likely mechanisms in hookah-related cardiovascular disease pathogenesis.

  • Tech and Telephone Smoking Cessation Treatment for Young Veterans With PTSD

    open to eligible people ages 18-39

    This project aims to enhance the scalability of an office-based smoking cessation treatment protocol for veterans with PTSD, integrated care (IC), by adapting it to be delivered over the telephone and to incorporate mobile technology components. Mobile technology components include: (1) the Stay Quit Coach (SQC) mobile application (app), and (2) the iCO mobile Smokerlyzer, a smartphone-compatible carbon monoxide monitor. Eighty U.S. military veteran smokers with PTSD, ages 18-39, will be randomized to receive either: (1) the telephone-and technology-facilitated intervention (n=40), or (2) the current standard of care (referral to the VA telephone Quitline) (n=40) as a control. All participants will receive a baseline (Week 0) office visit and will optionally be prescribed nicotine replacement therapy (NRT). Participants in the intervention condition will receive eight 20- to 30-minute video or telephone counseling sessions and be asked to use the SQC app and iCO Mobile Smokerlyzer. Control participants will receive up to eight weekly proactive telephone sessions through the VA telephone Quitline. Assessments will occur at baseline (Week 0), treatment end (Week 8), and at three months (Week 12) and six months (Week 24) post-randomization. The primary aims of this pilot randomized controlled trial are: (1) to assess the feasibility and acceptability of the intervention; and (2) to assess the impact of the adapted IC intervention on treatment retention compared to treatment as usual (i.e., VA Quitline).

  • 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.

  • Effect of Packaging on Smoking Perceptions and Behavior

    Sorry, in progress, not accepting new patients

    The investigators are addressing two critical areas identified by the FDA: the impact of cigarette packaging and labeling on consumer perceptions and on smoking behavior; and the effectiveness of graphic warning labels on communicating risk of tobacco products. In a randomized controlled trial (RCT), investigators will enroll committed smokers who have no intention of quitting in the next 6-months. The three study arms will be: a) a blank pack with all marketing materials removed (PP); b) The Australian graphic warning images (Australian model-AM); or c) a standard pack with all marketing materials unaltered (ST). The study includes a three month purchasing intervention and continued follow-up through 12 months. Throughout the study interactive text messaging assessments will be used to measure acute and persistent impact of labeling and marketing on perceptions of tobacco products, subjective effects of consumption, awareness of tobacco-related harms, tobacco use behavior, and quitting motivation. At three separate time points, participants will: a) complete a web-based questionnaire b) provide a saliva sample for cotinine analysis. The rigorous design and extensive objective measurements are significant innovations on the currently published research in this field and should lead to significant advances in tobacco regulatory science.

  • Financial Incentives for Smoking Treatment II

    Sorry, accepting new patients by invitation only

    Financial incentives for motivating changes in health behavior, particularly for smoking and other morbid habits, are increasingly being tested by health insurers, employers, and government agencies. However, in using incentive programs for smoking cessation, key unanswered structural and theoretical questions remain regarding their effectiveness, acceptability to patients, and economic sustainability. This trial aims to advance the science and implementation of financial incentives for smoking cessation interventions among high-risk, hospitalized smokers. The investigators will pursue two specific aims: 1) comparing the impact of three approaches for smoking cessation on smoking abstinence, use of evidenced-based therapy, and quality of life and 2) comparing the short-term and long term return on investment of using goal directed and outcome-based financial incentives to promote smoking cessation.
