Title: Effects of smoking on ACTH and cortisol secretion

The relationships among changes in plasma nicotine, ACTH, and cortisol secretion after smoking were investigated. Ten male subjects smoked cigarettes containing 2.87 mg nicotine and 0.48 mg nicotine. No rises in cortisol or ACTH were detected after smoking 0.48 mg nicotine cigarettes. Cortisol rises were significant in 11 of 15 instances after smoking 2.87 mg nicotine cigarattes, but ACTH rose significantly in only 5 of the 11 instances where cortisol increased. Each ACTH rise occurred in a subject who reported nausea and was observed to be pale, sweaty, and tachycardic. Peak plasma nicotine concentrations were not significantly different in sessions when cortisol rose with or without ACTH increases, but cortisol increases were significantly greater in nauseated than in non-nauseated smokers. This data suggest that smoking-induced nausea stimulates cortisol release by stimulating ACTH secretion and that cortisol secretion in non-nauseated smokers may occur through a non-ACTH mechanism.
