Sensory perception is a key determinant of smoking behavior and, therefore, reinforcement and addiction. The tobacco industry has conducted extensive research on the chemosensory and physiological effects of menthol in tobacco smoke and has actively promoted menthol's sensory characteristics. ⋯ The industry considers menthol to be an important tool for modulating the sensory effects of nicotine in different product variations, particularly those designed to be acceptable to "starters" or people interested in quitting. Regulatory efforts should consider that menthol enables the tobacco industry to customize a highly addictive product in a manner that contributes to initiation and deters cessation due to its chemosensory effects.

Comparative Study
Behavioral effects of nicotine withdrawal differ by genetic strain in male and female adolescent rats.
Gender and ethnicity are powerful predictors of initiation and maintenance of cigarette smoking in adults but less is known about their role in smoking in adolescents. Consistent with human studies, rat models also reveal sex and strain differences in response to nicotine administration. ⋯ Results indicate that nicotine withdrawal in adolescent rats depends on sex and strain.
