Capsaicin concentration at the urge-to-cough and the cough thresholds before and after placebo gum administration in the NS (solid bars) and SM (hatched bars) groups, and in the SM group before and after nicotine gum administration (open bars). The urge-to-cough threshold occurred at a lower capsaicin concentration compared with the cough threshold. There were no differences between groups (NS vs SM), treatments (nicotine vs placebo) or trials (pre- vs post-trial). * indicates a significant difference from the corresponding urge-to-cough threshold.
