WTF. Where did that list come from? Thetruth.com? That's got to be a list of all aditives used in cigs ever. I'm sure that all that shit isn't put into every pack. I smoke way too much and I can tell you why we don't cough. After a while you get used to the drag you take. I rarely cough when smoking pot. Only when I accidently take a hit thats too big. I allways know exactly how much I'm taking in when taking a drag of a cig.
