Addiction and Behavior Related to Menthol Cigarette Substitutes — MENTHOL  

Smoking (Tobacco) Addiction Clinical Trial

Official title: Addiction and Behavior Related to Menthol Cigarette Substitutes

Status Completed

Clinical Trial Summary

The goal of the proposed study is to examine the abuse liability and substitutability of plausible menthol cigarette alternatives currently on the market, including menthol filtered little cigars (mFLC), menthol roll-your-own (mRYO) pipe tobacco and cigarette tubes, and non-menthol cigarettes (nmC). In addition, the study will elucidate real-time mechanisms including product characteristics and perceived effects associated with greater substitution.

Clinical Trial Description

Using an in-laboratory and ad libitum outpatient mixed design, 80 current menthol cigarette smokers will complete a three phase, 3 week study: in Phase 1, utilizing a randomized crossover design, participants will complete 5 smoking sessions, each session smoking a different product examining each participants puff topography while sampling the product, the products' ability to suppress nicotine craving/withdrawal, and the product's demand indices. Products will include participants usual brand menthol cigarette (UBMC) as well as 3 commercially-available alternatives, including an mFLC, a pre-assembled mRYO product (menthol tobacco and non-menthol tube), and an nmC. All sessions will occur following 12 hours of nicotine abstinence and be separated by 48 hours. In Phase 2, participants will select their preferred study product from Phase 1 and be instructed to completely substitute the product for their UBMC for one week. Participants will complete ecological momentary assessments (EMA) during this period to more accurately assess degree of substitution and perceived effects in real time. In Phase 3, participants will complete a final in-lab visit to assess the substitutability of their preferred product, under simulated ban conditions using a progressive ratio task. In all phases, multiple domains of abuse liability will be assessed, including product administration (in-lab puff topography and EMA self-report measures), product liking and craving and withdrawal suppression (in-lab and EMA self-report), and a hypothetical purchase task to simulate demand. ;
