Let me qualify that by stating that EXCESS alcohol can cause more physical and social damage.
Alcohol is qualitively different from nictoine in as much that moderate amounts of certain types of drink, like red wine, can be beneficial to health. It also differs in as much that a drinking person next to you, does not recycle the waste elements of his/her actions through your body. He goes to the rest room to safely get rid of that. Smokers pollute the air that non-smokers breathe, and passively and involuntarily, raise their CO2 levels in their blood.
Excessive alcohol drinking has to be tackled in a different way. One measure could be, at least in the UK, where we have the phenomenon of binge drinking, cases of drunkeness ending up in casualty, should be invoiced for their treatment, and not get it free at the point of delivery. A breathaliser test exceeding an minimum specified amount of alcohol, will generate the invoice.
Pricing is another method, but this is socially divisive, and has the capacity to motivate determined poorer drinkers to divert funds from family essentials to buy the more expensive alcohol. Prohibition does not work, so publicity regarding the dangers of excessive alcohol is required plus new and real research to determine the actual number of units consumed to cause damage. The current unit maximums were based on nothing but guesswork.
