Effects of buprenorphine versus buprenorphine/naloxone tablets in non-dependent opioid abusers.

abstract：RATIONALE:Human behavioral pharmacology studies can examine how medications that target different neurotransmitter systems influence different aspects of smoking. Naltrexone and bupropion have been shown to alter ad lib smoking behavior; however, medication effects on nicotine reward in a cigarette choice paradigm have...
