Indoor-smoking bans have made life in the workplace more difficult for addicted smokers, but only 4 percent of large employers offer comprehensive stop-smoking services to employees, the Associated Press reported Dec. 19.

The findings clash with the fact that 82 percent of employers said in a second study from the National Business Group on Health that they believe that they should help workers quit, if for no other reason than it costs firms thousands of dollars a year in lost productivity and smoking-related medical expenses and illness for each smoker they employ.

Smoking is now banned by most large employers, but 78 percent of workers in smoke-free offices said bans alone are not enough to get them to break their addiction. The survey of employers and employees appears in the American Journal of Health Promotion.
