title: Urinary adrenaline concentrations during 10 days of smoking abstinence.
abstract: Urinary adrenaline concentrations were measured in 17 subjects during 10 days of cigarette abstinence. Adrenaline concentrations dropped significantly in the first 3 days of cigarette withdrawal. This was followed by a significant rise. More subjects showed a U-shaped function of adrenaline over time than would be expected by chance. The evidence suggests that the drop in urinary adrenaline concentration following cigarette withdrawal does not merely constitute a return to a non-smoking state, but includes an element of rebound resulting from loss of a component of smoking, probably nicotine, to which adaptation has occurred.
