Warb not everyone who smokes funnels it into the face of someone trapped in the room with them.

Everyone who drives funnels crap into the general environment, the air pollution levels caused by puffing away is practically non existent compared to cars but you can chose a car in colour you like without the need of a great big pair of clogged up lungs painted on the bonnet.

There is a lot of nonsense about passive smoking put around.

It is pretty bad in a poorly ventilated domestic environment especially in a car and around children.

But you aren't going to get cancer from someone passing you in the street smoking.

You are more likely to if you live in a city with too much traffic fumes.

As for violence under the influence of booze it's a undeniable reality which you just don't experience under the influence of nicotine.
