Scientists claim some people can hold their drink better than others because they have a "happy hour" gene.
Researchers found that those who had the genetic make up were able to become hardened to the affects of alcohol and therefore able to drink more. Those without it would not be able to consume as much before becoming drunk or falling asleep.
Human studies have pointed to a strong genetic component to alcoholism, but pinpointing the genes involved has proved difficult. Research suggests that the ease with which an individual gets drunk is a predictor of alcohol risk. Evidence suggests that people who can "take their drink" and have low sensitivity to alcohol are more likely to become addicted.
The findings could help scientists find a cure for alcoholism by deactivating the gene and making those with a high tolerance to drink more sensitive to its effects.
