Binge-Drinking Gene' Discovered, King's College London Study
Scientists believe some people have a gene that hard-wires them for binge drinking by boosting levels of a happy brain chemical triggered by alcohol. The gene - RASGRF-2 - is one of many already suggested to be linked with problem drinking, PNAS journal reports. The King's College London team found animals lacking the gene had far less desire for alcohol than those with it.
