Active clinical trials for "Tobacco Use Disorder"

This randomized phase II trial studies the safety and effects of acetylsalicylic acid (aspirin) taken continuously or intermittently on gene expression in the nasal tissue of current smokers. Smokers are at increased risk of developing lung cancer. Acetylsalicylic acid may be useful in preventing lung cancer.

The purpose of this study is to test the effects of a computerized, self-directed Motivational Enhancement Therapy program for adolescent substance use (iMET), in comparison to clinician-delivered MET and Treatment As Usual (TAU), on treatment engagement and substance use. The investigators hypothesize that both iMET and MET will be more effective than TAU in engaging/retaining patients in treatment and in reducing substance use during a 12-month follow-up period. The investigators also hypothesize that Self-directed iMET will be as effective as the clinician-guided MET in increasing treatment engagement and abstinence during the 12-months follow-up period.

The aim of the present study is to compare cognitive scores (attention, executive function and working memory) of different e-Cigarette strength with usual cigarettes.

The current literature in social epidemiology and public health suggests that low financial savings has an unsurprising negative relationship with subjective well-being, and increases the odds of making visits to a healthcare provider, receiving a chronic disease diagnosis, and experiencing medical disability. Earn.org is a community-based non-profit based in San Francisco with a mission to help low-income workers build lifelong savings habits and financial capability. The organization is one of the largest providers of "goal-based savings accounts" or "matched savings accounts" in the US. The investigators propose to conduct a randomized controlled trial to determine the health effects of Earn's savings program. Through this trial, the investigators will test three principal hypotheses: (1) Participants in the Earn account, as compared to a control group, are hypothesized to demonstrate improved scores on mental health scales assessing depression and anxiety. (2) Participants in the Earn account, as compared to a control group, are hypothesized to experience lower odds of harmful behaviors associated with stress, specifically tobacco and alcohol abuse. The investigators hypothesize that the effect on behaviors will be of smaller effect size, and more delayed, than the effect on mental health outcomes, judging from similar effects observed in the micro-credit literature. (3) The mediating variables between Earn account participation and beneficial health outcomes will include increased optimism and internal locus of control.

The purpose of this Pilot feasibility study is to find out the effect of different behavioral treatments along with different duration of a drug called varenicline, on smoking behavior and quitting smoking. Varenicline, also known as Chantix™, is an FDA-approved medication that has been shown to help people quit smoking.

The purpose of this study is to determine, among a sample of general adult smokers, the effectiveness of three different counseling interventions for motivating quit attempts among smokers not yet ready to quit.

RATIONALE: Calcitriol may prevent lung cancer in patients with metaplasia or dysplasia of the lungs. PURPOSE: This clinical trial is studying the side effects and best dose of calcitriol in preventing lung cancer in current smokers and former smokers at high risk of lung cancer.

Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. Curcumin is a compound found in plants that may prevent colon cancer from forming. This phase II trial is studying how well curcumin works in preventing colon cancer in smokers with aberrant crypt foci.

The purpose of this study is to examine the role of progesterone (a hormone found in both men and women) on stopping cocaine use. The study will examine whether the medication, in combination with behavior therapy will decrease cocaine use, cigarette smoking, withdrawal symptoms, impulsivity and stress.

The purpose of this research study is to determine whether combining electronic nicotine delivery systems (ENDS) with nicotine patch treatment will augment abstinence rates compared to either treatment alone.
