> Apparently people smoked on submarines for a while.
More than ‘a while’. https://pmc.ncbi.nlm.nih.gov/articles/PMC4344412/:
“In the mid 1970s smoking was allowed virtually everywhere; by 2000 there were only two allowable smoking areas-each approximately 6 feet by 6 feet-one in the engine room and one up forward.
[…]
In 2009, a working group was established to prepare for a December 31, 2010 deadline for prohibiting smoking below decks on deployed submarines”
That paper also says:
“In 1993, based on reports of the dangers of secondhand smoke, Captain Stanley W. Bryant, the commanding officer of the USS Theodore Roosevelt, announced a ban on smoking aboard the ship starting in July 1993 and proposed eliminating tobacco from the ship's store. These actions elicited a strong and swift tobacco industry response. As described by Offen et al., tobacco friendly members of Congress challenged the policies and enough pressure was generated to force the reversal of both the ban on smoking and the prohibition of cigarette sales aboard the ship”
My time in submarines at sea just coincided with the last few years where smoking on submarines was still authorized.
It was awful, just awful. Especially in a space as cramped as a submarine and with a common ventilation system, you can't just put the smokers in a convenient spot all to themselves, they're always going to be near something the rest of the crew needs to access.
