Wanted to know if anything in cigarrette thats causes other addictions besides nicotine?

Tricky question: The only CHEMICAL in cigarettes known to cause physical dependency is nicotine. However, addiction is always more than physical dependency, and the oral nature of smoking, the highly repetitive actions (taking a drag 30 times with each cigarette, 20 cigarettes a day= 600 repetitive actions) also produce their own "addiction." The linkage to waking up, meals, phone calls, sex etc. ditto.
