Harvard College Alcohol Study (CAS)
• National sample of 140 4-year U.S. colleges
• Random sample of students at each college
• Mailed survey– 1993: N=15,103 (70% response rate)– 1997: N=14, 251 (60% response rate)– 1999: N=14,138 (60% response rate)– 2001: N=10,904 (52% response rate)

Benefits of Smoke-Free Dorms
• Protect nonsmokers from passive smoke
• Reduce a fire hazard
• Promote a nonsmoking campus norm– Discourage tobacco use initiation– Discourage progression of occasional smoking
to regular use– Boost success of smokers trying to quit
Prevalence of Smoke-free Dorms Harvard College Alcohol Survey, 2001
39% of students live in university housing
23% want smokefree
59% smokefree
(36% in 1999)
18% do not want smokefree
