Smoke-induced weight loss was reversed 12 weeks after CS cessation.

<p>Male BALB/c mice were either exposed to 6 cigarettes/day, 6 days/week (▪) or sham handled (▴) for 16 weeks. After smoke exposure, groups of mice were then exposed to room air without cigarette smoke for either 4 weeks (∇) or 12 weeks (♦). For all groups body weight was determined weekly. Data are shown as mean ± SE for n = 14–18 per treatment group.
