Aye, sleepy Rosie. You could say that any legislation that does anything other than ban tobacco is immoral.

Looking at The UK, (I know this started as an American story, sorry folks.)

35% of GP appointments are tobacco related, a third of NHS spend is tobacco related. (You may be in for a back injury, but your coronary heart problems and lung capacity make it awkward to operate, hence more expensive treatment, your general poorer health makes a longer hospital stay etc etc.)

We pass that legacy on to our children if we smoke around them...

I didn't watch my Dad smoke throughout my childhood. He stopped when I was 10, just in time to die of lung cancer when I was 12.
