Title: Effect of Banning Menthol Flavorant on Cigarette and E-Cigarette Use
Brief Summary: In this pilot study, menthol cigarette smokers will be randomized to one of three experimental marketplaces: 1) a condition simulating a ban on menthol cigarettes but not menthol e-cigarettes (condition A); 2) a condition simulating a ban on both menthol cigarettes and menthol e-cigarettes (Condition B); and 3) a condition in which menthol is not banned for either product (Condition C - the control condition). All conditions would have medicinal nicotine available if subjects decide to quit tobacco products entirely. At visits occurring every two weeks over a 6 week period, subjects will receive "credits" that they could exchange for any product available in their randomized marketplace condition. Outcomes include the amount of each tobacco product used.

4. Positive mannitol test.

Furthermore, all of the below inclusion criteria:

Patients who are diagnosed with other chronic respiratory disease than asthma during the study period will also be excluded, as well as patients who during the study period require more asthma medicine than the planned study medication.

Any participant who wishes to leave the study, for any reason, including unacceptable side-effects, during the study period will be excluded, as well as anyone who wants to withdraw their recorded data from the project after the study period has ended.

In case of unacceptable side-effects to varenicline resulting in immediate cessation of treatment with this drug, the participant will continue visits unchanged, but he/she will be excluded from the calculations of tobacco cessation succes-rate. However, varenicline cessation up to 4 weeks after treatment start with varenicline will result in exclusion and replacement of the participant.

Cessation of treatment with budesonide will result in exclusion from the rest the study. The person will not be replaced. The data recorded from the participant until the last visit before cessation will be used.
