Experts say they have found a “tipsy” gene that explains why some people feel alcohol’s effects quicker than others.
The US researchers believe 10% to 20% of people have a version of the gene that may offer some protection against alcoholism.
That is because people who react strongly to alcohol are less likely to become addicted, studies show.
The University of North Carolina said the study aims to help fight addiction, not pave the way for a cheap night out.
Ultimately, people could be given CYP2E1-like drugs to make them more sensitive to alcohol – not to get them drunk more quickly, but to put them off drinking to inebriation, the Alcoholism: Clinical and Experimental Research journal reported.
