Note 1: Irregular shapes represent counties. Black-outlined circles represent a local municipality that passed a restriction at that location.
Note 2: Alaska and Hawaii are not shown. The only restriction in Alaska is a comprehensive ban in the town of Palmer. The only restriction in Hawaii is a statewide ban on e-cigarette use specifically on grounds of the State Department of Health.
Note 3: States whose only statewide restrictions apply to correctional facilities are not colored. These states are Colorado, Kansas, Oklahoma, and South Dakota.
Note 4: Restrictions superseded by higher level geographic unit restrictions are not shown. Note that some county-level restrictions only apply to unincorporated areas; therefore, local ordinances of the same category are retained in the figure for such municipalities.
