Effect of 5,7-dihydroxytryptamine on the development of tolerance to ethanol.

abstract：OBJECTIVES:In recent years, there has been growing research interest in using nicotine replacement medications to aid smoking reduction prior to a quit attempt. Gaining a better understanding of how treatments influence smoking reduction may allow for better tailoring of treatments and, ultimately, better cessation out...
