Effects of menthol use and transitions in use on short-term and long-term cessation from cigarettes among US smokers

7/10/21--This study was designed to estimate the effect of menthol use and transitions in use (switching to or from menthol) on short-term and long-term cessation from cigarette smoking and whether this differed across demographic groups (age, sex, race). Results demonstrate that menthol impaired menthol smokers’ attempts to quit smoking but switching from menthol improved success. This suggests that removing menthol may improve menthol smokers’ success during quit attempts. Read

E-cigarette manufacturers’ compliance with clinical trial reporting expectants: a case series of registered trials by Juul Labs

E-cigarette-inclusive smoke-free policies, excise taxes, tobacco 21 and changes in youth e-cigarette use: 2017-2019

Results show state-level ESF and T21 policies could be effective for limiting growth of youth e-cigarette use despite an overall national increase. Higher e-cigarette excise tax rates may be needed to effectively reduce youth e-cigarette use. Read
