Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To examine if switching from menthol to non-menthol cigarettes will change the dose-effect curves for positive subjective effects and alleviation of smoking urges as a function of nicotine delivery rate in smokers.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

A placebo-controlled study that will recruit male and female menthol nicotine dependent smokers. Following screening and evaluation as described above, eligible participants will be enrolled in the study which will last about 4 weeks. Eligible, participants will be randomized to menthol or non-menthol smoking condition for 2 weeks (Phase 1) and then will be switched to the alternative condition for another 2 weeks (Phase 2). The smoking condition will be open label. Participants will be provided with free cigarettes in Phases 1 and 2. For the menthol condition, participants will be provided their usual brand of menthol cigarettes and for the non-menthol condition, they will be provided a matched-brand non-menthol cigarette (e.g., Newport Non-Menthol Gold 100s for those who smoke Newport Menthol Gold 100s). In week 2 of each Phase, participants will have a test session. Each session will include 3 infusions in the same order: nicotine (1 mg per 70 kg body weight) delivered over 5 minutes, saline and nicotine (1 mg/ 70 kg) delivered over 2.5 minutes. Once the participants complete the test session, participants will be crossed-over to the alternative treatment. The period between the 2 Phases will not be longer than one week.

Allocation Method

RANDOMIZED

Intervention Model

CROSSOVER

subjects will be unblinded to smoking menthol or non menthol for two weeks before each test session. Each session will include 3 infusions in the same order: nicotine (1 mg per 70 kg body weight) delivered over 5 minutes, saline and nicotine (1 mg/ 70 kg) delivered over 2.5 minutes. Once the participants complete the test session, participants will be crossed-over to the alternative treatment.
