It is a matter of what is socially acceptable. I wasn't that many years ago that much of the population was in to opium in various forms. Soldiers had fags in their ration packs in ww2. At the moment booze is still fashionable but fags are not. The govt is in to private enterprise so they say, but the country would go broke if they banned booze and smokes and people made their own, and the prisons would be empty if they legalised pot. Don't vote, it only encourages them.
