Why do people smoke cigarettes?

[Motec]

I smoke because I like smoking.

I enjoy a ciggy after a meal, definitely after blowing my load, when I have a drink I'll have a smoke, I do so at work due to sheer boredom in the oilfield, maybe 3-4 a day. Its not like I miss the cash, if I need to worry about 20 bucks a pack, I've fucked up in life somewhere else.

No two people will be the same. Some people cant afford it, some smoke 50 a day, some need one the moment they wake up. Others just like the effect of nicotine.
