Menthol facilitates the intravenous self-administration of nicotine in rats
Menthol is preferred by ~25% of smokers and is the most common flavoring additive in tobacco and electronic cigarettes. Although some clinical studies have suggested that menthol facilitates the initiation of smoking and enhances the dependence on nicotine, many controversies remain. Using licking as the operant behavior, we found that adolescent rats self-administering nicotine (30μg/kg/infusi...
متن کاملReboxetine: attenuation of intravenous nicotine self-administration in rats.
The ability of reboxetine, a selective inhibitor of the norepinephrine transporter and noncompetitive antagonist at neuronal nicotinic receptors, to alter nicotine self-administration in rats was compared with that of mecamylamine, a classical noncompetitive antagonist at nicotinic receptors. The ability of reboxetine to alter sucrose-maintained responding was also examined to assess the specif...
متن کامل'Nicotine deprivation effect' in rats with intermittent 23-hour access to intravenous nicotine self-administration.
Our previous work demonstrates that rats allowed extended 23-hour access to intravenous nicotine self-administration (IVSA) display voluntary, dose-related levels of nicotine intake (i.e., higher doses result in higher intake) that remain stable across 40 days. This study examined whether an escalating dose regimen with intermittent abstinence periods produces different levels of nicotine intak...
متن کاملNicotine Self-administration in Animals: a Reevaluation
Nicotine self-administration in animals is often viewed as compelling evidence that nicotine is reinforcing to animals and as corroborating the widely accepted thesis that nicotine is a major cause of smoking. This review examines the studies of nicotine self-administration in animals in the past two decades, focusing on threats to the internal and external validity of these studies and on the ...
متن کاملEffects of a Selective Cannabinoid CB2 Agonist and Antagonist on Intravenous Nicotine Self Administration and Reinstatement of Nicotine Seeking
Over the last decade there have been significant advances in the discovery and understanding of the cannabinoid system along with the development of pharmacologic tools that modulate its function. Characterization of the crosstalk between nicotine addiction and the cannabinoid system may have significant implications on our understanding of the neurobiological mechanisms underlying nicotine dep...
