Please don't shift the goal posts, the argument I was responding to said that continuing to smoke is merely a choice. I'm not arguing that smoking should be allowed on submarines or anything of the sort, just dispelling this one specific falsehood that attempts to paint addicts as lazy or otherwise inferior just because they can't wake up one day and quit their addictive behavior.
What next, are you going to obligate the military to provide all the alcohol and hard drugs any addict may desire in the next 6 months?
There's so many reasons you get disqualified from serving in certain positions in military. Being addicted is just one of them.
