When the fire-safe cigarettes first emerged about 1 year ago, my wife and I(both pack-a-day smokers) instantly noticed a foul aftertaste to the new cigarette papers. I smoked the same brand of cigarettes for 6 years and never noticed any foul taste or odd side effects of the chemicals in my tobacco. Suddenly I was getting headaches and my wife was having an upset stomach. We switched to a non FSC brand, and the side effects subsided. When no more brands of non FSC cigarettes were available, we switched to RYO (roll your own) cigarettes made by a $40 dollar machine. The side effects of FSC went away, and we went from spending about $300 dollars a month on cigarettes to about $65 dollars a month on tobacco and tubes, a savings of $2820 per year!
