There are few individuals in San Diego or anywhere else in the nation that would consider enrolling in a drug rehab program for a nicotine addiction. Yet this powerful habit-forming drug (as found in cigarettes and other tobacco products) can often be one of the most difficult substances to quit. In fact, an overwhelming majority of cigarette users are unable to quit without receiving some type of assistance, as individuals frequently experience difficult withdrawal symptoms when the body is denied nicotine. While medications and behavioral treatments have been introduced to help individuals overcome their addiction, it can still be quite difficult to quit.
