Rapid responses are electronic letters to the editor. They enable our users to debate issues raised in articles published on thebmj.com. Although a selection of rapid responses will be included online and in print as readers' letters, their first appearance online means that they are published articles. If you need the url (web address) of an individual response, perhaps for citation purposes, simply click on the response headline and copy the url from the browser window. Letters are indexed in PubMed.
Alcohol is a drug. We do not study other drugs by looking at their effect related to weekly intake. 28 grams of paracetamol taken by 4 grams daily for a week is therapeutic, taken in 1 day it could be fatal. By my recollection of looking at original papers for a study as a medical student, the issue with the data on alcohol and cardiovascular health was not just around confounders, but also whether studies distinguished, particularly for the 'moderate' drinkers, between the same overall consumption via binge or more regular but lower alcohol consumption. We know the symptoms of ethanol consumption change markedly with the level consumed, as do the biological effects. Binging induces much higher levels of the intermediaries of its breakdown, which may be more damaging than ethanol itself. We can clearly advise against bingeing, but I do not feel that this study provides the detail necessary to advise against moderate non-binge drinking.
