AB  - Addiction can result when substances, such as drugs or alcohol, co-opt the brain's natural reward system. Shohat-Ophir et al. (see the Perspective by Zars) explored this potential in Drosophila by examining the relationship between the natural reward stimulated by mating and the unnatural reward offered by ethanol consumption. Males deprived of mating increased consumption of ethanol, and, when permitted to mate after deprivation, their ethanol consumption decreased. At a mechanistic level, mating increased the neurotransmitter neuropeptide F (NPF), whereas mate deprivation decreased NPF levels. G. Shohat-Ophir, K. R. Kaun, R. Azanchi, U.
