In my initial post, I said there is no secondhand impact with drinking “like there is with smoking.” The secondhand hand impacts you mention are very different than those with smoking.
What I mean is that if one is consuming alcoholic beverages in close proximity to another person, that other person’s health is not impacted by the mere consumption. With smoking, on the other hand, if one is smoking a cigarette within close proximity to another person, that other person’s health can be impacted merely by the smoking. Because of that, it has led to smoking bans in public places, which has has had a significant impact on the numberof people who smoke. Also because of that, people quit smoking to avoid exposing people to the effects of smoking. For example, I know people who quit smoking once they had kids to avoid ever putting their kids in a position where they could take in secondhand smoke.
Also, what you are referring to is not the impact of the act of consuming alcoholic beverages by itself. You are referring to the impacts caused by alcohol abuse or drinking irresponsibly. The act of consuming alcoholic beverages by itself, even when done in close proximity to other people, does not have the secondhand impact. The act of smoking cigarettes by itself (if it is done in close proximity to others) does.
If I have a glass of wine with dinner every night while I sit and have dinner with my family, it will not impact their health in any way. If I were to smoke a cigarette or two with my meal every night while sitting there with my family, it could impact their health.
Millions of people who drink do so responsibly, and it has no ill health effects on anyone else even when having a drink near other people. Anyone who smokes around other people can expose those people to potential ill health effects.
Even taking the impacts of drinking you mention into consideration, it is the unique nature of the secondhand impact of smoking that has led to a significant decrease in the number of people who smoke.
