If a cigarette was the cause of the fire [we don't know anything confirmed yet] the smoking/non-smoking issue is a little weak. How many passengers sailed in the last 20 years? How many ships? cabins? How many ships caught fire? The statistics just aren't there to back up whether smoking should be banned. I see a lot of the officers on the ships smoking so, I really doubt if they would ban it, it was a disaster with Carnival paradise, they were losing so much revenue when they had it as a non-smoking ship. It will not happen.
