Not enough. Most people simply ignore tobacco as a substance and do not talk with their children, family and friends about it. It is addictive, it is dangerous for health but it should never be banned as it is being attempted on several countries.
Tobacco should be treated as a luxury, an indulgence, not something to label as a drug and criminalize. As you state and very well: this is prohibition. Puritanism never works and this will not be an exception.
