Comparison of intravenous cocaethylene and cocaine in humans.

abstract：RATIONALE:The antidepressant nortriptyline is a second-line pharmacotherapy for smoking cessation. Given that there is limited preclinical data available on the effects of nortriptyline on responses to nicotine, the present study sought to evaluate its effects on the reinforcing, discriminative stimulus (DS) and aversi...
