Incorporating nicotine dependence into addiction treatment.

An addiction treatment program devoted two years to preparing to become a smokefree treatment unit that addressed nicotine dependence as another drug dependency. Data collected from September 1990 to July 1995 on 263 admissions before becoming smokefree and 2182 admissions after making the transition revealed that going smokefree did not affect the incidence of premature discharges or aggressive behavior, and did not change the overall rate of program completion by either smokers or nonsmokers. During the first three months after going smokefree, the program completion rate dropped for both smokers and nonsmokers; by the fourth month, it had returned to previous levels. Seventeen months after going smokefree, the program completion rate was higher than it had ever been. This suggests that the drop in the program completion rate was due to the disruption caused by a significant programmatic change and not due to the unit's smokefree status, and that the increasing experience of staff in treating nicotine dependence resulted in improved patient outcomes.
