I assume you meant cigs? Whether it should be classed as a crime in certain circumstances then I would agree. I recall one guy that I used to work with crashing his car after he dropped a lit cig on his lap. Luckily for him, he wasn't injured but did make a mess of his car. Also, if using a mobile phone whilst driving a vehicle is classed as a criminal offence then so should smoking whilst driving.
Lets make sneezing illegal as well
