As an ex-smoker I can remember several times driving where the fag would stick to your lips as you tried to pull it out of your mouth. You ended up pullinf the tip off it, burning the fingers off yourself and trying to extinguish the cigarette in your lap at the same time and trying to stop it burning the seat.
Highly dangerous, and you were far less in control of the car than you would be with a dozen pints in you.
I regard smoking as a tax on the poor. From my own observations, more poor people seem to smoke than middleclass, I accept that this is a generalisation but that's the way it seems to me.
In the UK and on Contintenal Europe on the other hand smoking seems to be much more common in the middle classes than here.
I agree with RainyDay. People can smoke wherever they want, as long as it doesnt affect public places/kids. If I'm walking down the street or in a park etc enjoying the fresh air, the last thing I want is to be engulfed in, and get a lung-full of, smoke. And its not just one lung-full - every time you pass a smoker, its the same. And if you are in a queue downwind of a smoker, your hair and clothes get smelly from the smoke.
I live in Spain where every second person smokes. So walking down the street, its not that you get just one blast of smoke - instead it comes at you constantly from all sides. So yes, 'engulfed' is how I'd describe it.
