Most substance abuse treatment facilities allow residents to smoke, government findings show.

The Centers for Disease Control and Prevention and the Substance Abuse and Mental Health Services Administration reported Thursday that 49 percent of mental health and 35 percent of substance abuse treatment facilities have smoke-free campuses. The agency made recommendations as part of its report to encourage states to expand those numbers, and also to encourage facilities to provide medication, counseling, or nicotine patches or gum to patients who are smokers.
