Tobacco-free oral nicotine pouches (such as Zyn brand) are a less harmful alternative to cigarette smoking. Pouches, however, contain nicotine, and addictive substance that is not risk-free. The present study is evaluating how well nicotine pouches, at different nicotine levels, help people switch away from smoking cigarettes. People who smoke cigarettes will be asked to answer questions about their tobacco product use and provide breath samples and cheek swab samples at an in-person visit to MUSC Charleston. Participants will then be provided with a 28-day supply of nicotine pouches, and will be asked to switch from smoking to pouches over the course of 4 weeks. Finally, participants will complete a final visit at MUSC, and will answer more questions about their tobacco use 1-month later.
While cigarette smoking is detrimental to health and a known risk factor for cancer, e-cigarettes are thought to be less harmful but not entirely risk-free, and less is known about e-cigarette use and changes to health. The purpose of the present study is to evaluate changes in health that may occur when people stop using e-cigarettes. Participants who use e-cigarettes (and who never smoked, smoked in the past, or currently smoke) will be recruited to participate in a laboratory session followed by a week of abstaining from any nicotine use. Throughout the study, participants will provide biological samples for analysis of DNA damage, immune functioning, inflammation, and respiratory functioning at the MUSC Charleston campus. Results will provide insight into the health benefits of quitting vaping.
For patients in cancer care, quitting smoking is critical, but a significant portion of patients in cancer care refuse all components of tobacco treatment, even when offered proactively and free of charge. The proposed clinical trial will assess one harm reduction intervention, switching completely from cigarettes to e-cigarettes, among oncology outpatients who smoke and refuse traditional tobacco treatment.
The purpose of this study is to better understand tobacco outcomes using a commonly prescribed stop smoking medication (varenicline) and financial incentives for adults who also use cannabis. Varenicline is not FDA approved for e-cigarette cessation, but is FDA approved for cigarette cessation. We are also interested in how cannabis/marijuana and tobacco interact during a tobacco quit attempt. All participants will receive e-cigarette cessation treatment for 12 weeks. To qualify, participants must be between the ages of 18-40 and use both tobacco and cannabis. Participants do not need to be interested in quitting cannabis to qualify. This study is being conducted at three sites: the Medical University of South Carolina in Charleston, SC, Behavioral Health Services in Pickens, SC, and MUSC Lancaster

The purpose of this study is to evaluate the effectiveness of varenicline (sometimes known as Chantix) compared to placebo (an inactive substance) for the treatment of cigarettes and cannabis (marijuana). Varenicline is not FDA approved for the combination treatment of cigarette abstinence and cannabis reduction or abstinence. All participants will also receive counseling and access to online treatment modules during a quit attempt for cigarettes and a reduction attempt for cannabis. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely; therefore, no in-person visits are needed.
To qualify, participants must be 18 or older, live in South Carolina, use cigarettes and cannabis, and are interested in quitting cigarettes and reducing cannabis.
This is a research study to examine if and how patterns of use change over time among three different groups of tobacco users: 1) adults who exclusively smoke combustible cigarettes, 2) adults who exclusive use e-cigarettes, and 3) adults who use both. This is a naturalistic survey study, there is nothing required or requested of participants, other than to complete our surveys. Participants do not need to quit or reduce their smoking/e-cigarette use if they do not want to. They do not need to travel for this study; it is completely remote and they can participate from your home.
Participation in the study will take place over a period of 12 months in the form of: 1) Monthly Surveys (13 total), 2) Daily Diaries for the first 90 days, 3) Follow-Up Diaries in each of the 7 days leading up to each monthly follow-up survey, and 4) Submission of Breath Samples (13 total).
Smoking is one of the main public health problems. Smoking cessation is difficult because of nicotine dependence. Repetitive transcranial magnetic stimulation (rTMS) over the frontal head has shown to be effective in the reduction of cigarette consumption and craving. In this study, we will evaluate the efficiency of a new form of rTMS called intermittent theta-burst stimulation (iTBS) for smoking cessation.
Many people smoke cigarettes and use e-cigarettes, and have a hard time stopping. Nicotine replacement therapy medications, such as nicotine patches and lozenges, have been shown to help people quit e-cigarette use. The purpose of the present study is to see how well nicotine patches and lozenges help people quit both smoking and vaping, and to determine if higher doses of the medication work best.
The goal of this project is to better understand the relationship between tobacco/nicotine and cannabis using behavioral economics during a tobacco/nicotine quit attempt. All participants will receive tobacco/nicotine cessation treatment (smoking and/or vaping treatment) for 12 weeks. To qualify, participants must be between the ages of 18-25 and use tobacco products (smoke cigarettes and/or vape nicotine) and use cannabis (in any form). Participants do not need to be interested in quitting cannabis/marijuana to qualify. This study is being conducted by the Medical University of South Carolina. All procedures are conducted remotely and there is no in-person visits are needed.
