What are the addictive chemicals in cigarettes other than nicotine?

I cannot answer the question specifically but I can tell you FOR SURE having been put myself in the guinea pig position unwittingly that the CAMEL corporation and most likely others PUT BRAND ADDICTIVE additives into their cigarettes. I am 100% positive of this fact as far as the Camel corporation is concerned. I was addicted to 2 brands at once. I'd go all day or 2 days without a Camel cigarette and start to feel unfulfilled and restless (still smoking my normal brand) and AS SOON AS I lit up that camel would feel an immense sense of relief and those associated feelings would be totally alleviated. It happened time and time again over a period of 2 months until I finally kicked the camels. No scientist or BS statistic will ever change my mind on this FACT. Something has to be done. What is Obama really doing about this?
