According to a study published in Science Daily, researchers at the University of California, San Francisco, found that rejected male fruit flies had a tiny neuropeptide F molecule in their brains that makes them drink alcohol far more than their sexually satisfied counterparts.
The molecule’s levels were higher in sexually satisfied males than in those who had no sex, leading researchers to speculate that their work could shed light on the brain mechanisms behind human addiction.
A similar human neuropeptide Y molecule may also link social triggers to behaviours such as heavy drinking and drug abuse.
