Official title
Impact of Cigar Flavor on Tobacco Use Behaviors and Addiction in Dual Users
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to understand addiction to filtered cigars (FCs) compared to cigarettes in young adults, ages 21-34, who smoke both cigarettes and cigars. We are also looking to see if flavors, such as fruit or menthol, make FCs more addictive and if there are differences between men and women. Participants will receive 2 weeks supply of FCs, one week flavored and another week unflavored. You will be randomized (like flipping a coin) to which type of FC you will receive first. The study will: * take about 3-4 hours of your time per week over 3-5 weeks. * be conducted remotely by phone, video call, email, and mail. * require a smart phone to answer 5 quick surveys a day * you will need to answer 4 weekly surveys * take part in a weekly video or phone call with research staff * supply three saliva samples to be later tested for nicotine and other toxicants * and use a device to measure your carbon monoxide levels four times a day. You will be compensated for your time.
