Do "safe limits" for drinking have a firm scientific basis?
Sir, Many Times readers will have enjoyed their weekend all the more as a result of the allegation that safe limits for drinking, developed in 1987, have “no firm scientific basis whatsoever” (report, Oct 20).
However, this is far from the case. Twenty years ago we knew that there is wide individual variation in sensitivity to alcohol, probably largely genetically determined. In the future we may be able to quantify an individual’s risk of cirrhosis, suicide or alcohol dependence from his or her genes, but until then the only way to avoid harm reliably is to stick to these clear and still valid limits.
