简要总结
Background:
- The success rate for those who attempt to quit using tobacco products is only about 5 percent. Many people who try to quit do so without seeking professional help. Several kinds of nicotine replacement therapy (NRT) are available without a prescription. However, prescription drugs and mental health counseling can also help people stop using tobacco. Combining NRT and/or medication with counseling can increase success rates. Researchers want to study what kinds of tobacco cessation treatments are most successful. This may help develop better treatments and determine who will respond best to them.
Objectives:
- To provide treatment for tobacco use.
- To identify factors that affect how well people respond to treatment.
Eligibility:
- Individuals at least 18 years of age who are trying to stop using tobacco products.
Design:
- This study will last up to 1 year. Treatment may last up to 36 weeks. Treatment may include counseling, NRT (patches and/or nicotine lozenges), or prescription medication (varenicline or bupropion). Treatment will be determined by a study doctor.
- Participants will also have three study visits at 4, 6, and 12 months after starting treatment. Each visit may take up to 2 hours. At the study visits, participants will have different kinds of tests. They will provide blood and urine samples, and have carbon monoxide breath tests. They will also fill out forms about mood and tobacco cravings.
- During treatment, participants will have clinic visits once or twice a week for counseling and to monitor tobacco use and withdrawal symptoms. Counseling sessions will work on dealing with tobacco cravings. Each visit may take up to 90 minutes.
详细描述
Objective
The purpose of this protocol is to create a mechanism whereby the intramural program of the NIDA in Baltimore, MD can evaluate and treat a broad range of people who use tobacco products. Through this protocol, participants will receive state-of-the-art treatment for their tobacco use. The secondary objective is to investigate predictors of success in tobacco-use-cessation treatment.
Study population
Participants will be individuals who present to the NIDA IRP seeking to quit tobacco use (smoked and smokeless). Enrollment may occur as part of participation in another NIDA IRP study. We will enroll up to 1000 participants. All individuals who give signed informed consent and who attend at least one study visit will be considered evaluable. We will not replace study dropouts.
