Effects of cigarette smoke (CS) exposure on body weight (BW) and blood pressure (BP) under normal physiological conditions. Mice were divided into air-exposed (control) and CS-exposed (smoking) groups. CS exposure for 16 wk had no significant effects, but 32 wk of CS exposure significantly blunted BW gain (A) and increased BP (B) compared with control mice. Values are means ± SE; n = 5–7 mice/group. **P < 0.01 and ***P < 0.001 vs. control.
