Methodology Notes

Newly enacted state tobacco-control legislation is downloaded from Westlaw, an on-line legal database. CDC, Office on Smoking and Health (OSH) searches the Westlaw LEGIS-ALL database for all 50 states and D.C.’s enacted bills for the quarter using date restrictions. The bills are coded according to variables identified by CDC, OSH, which include the comprehensiveness of the law, includes smoking areas permitted or required, separately ventilated smoking areas required, and no smoking allowed (i.e., banned). In some cases, data on enforcement authority, penalty for violation, and signage required are also collected.

Vehicles with children are tracked in the STATE system as "Personal vehicles". To be counted as prohibiting smoking, states should be coded using the following criteria in the STATE system: In the STATE system under Restrictions: Type of Restriction in Personal Vehicles = Banned AND In the STATE system under Additional Requirements Requires a Child in the Vehicle = Yes
