if my smoking habit can effect my son, who is 16 now ?

@firefall: I smk in front of my son regularly. I am a chain smoker.

@sumita123: well, it does up his chances of cancer from second-hand smoke, a bit, although nothing like as high as the chances for any actual smoker.

@firefall: for me ,???

@sumita123: when you smoke in a room, part of the carcinogens go into your lungs, part go into the atmosphere where they can get breathed in by others in the room. So he will take in -some- carcinogens, but you'll take most of them in; his chance of getting cancer goes up a bit, yours goes up a lot more.

@firefall: I never let him smk a single drag.

@sumita123: that's good :D
