A rebuttal to Kuki and Tina:
This is not political and certainly does not advocate banning all activities detrimental to life and limb, not even smoking.
"While we cannot and should not ban it entirely, we should continue to make it so difficult and inconvenient for the smoker to find an acceptable place to smoke that thier numbers continue to drop. On cruise ships this could include a ban in the cabins, leaving them only able to smoke on the designated side of the ship and in the casino. "
That still leaves plenty space for them to smoke until they drop. They can install the same smoke detectors in the cabins that they have in airplane lavatories, which are so sensitive cigarette smoke set them off.
