Military personnel may live in military housing on installations or in private residences in the surrounding community. Many military personnel are transient and live on or off an installation for only a few weeks, months, or years until they are reassigned. This makes it important that exposure to tobacco residue be minimized in living quarters. DoD and the armed services cannot mandate tobacco restriction in private residences off an installation, but they do have authority over on-installation housing. All of the armed services have policies that address tobacco use in living areas on military installations (see Table 5-5). For some lodging restrictions, the policies state that reasonable accommodations may be made for smokers, such as designating smoking areas or buildings, but in general the needs of nonsmokers prevail (see, for example, Air Force Instruction 40-102, June 2002). The 1999 Tobacco Use Prevention Strategic Plan requires a review of service policies and practices on prohibiting tobacco use in all common areas used by nonusers. Each of the armed services specifies that tobacco use is prohibited in common areas of living quarters and lodging (see Table 5-5).
