An Act amending the act of June 13, 2008 (P.L.182, No.27), known as the Clean Indoor Air Act, further providing for definitions and for prohibition.

SB 263 updates Pennsylvania's Clean Indoor Air Act by explicitly including electronic cigarettes in the definition of "smoking." It modifies restrictions for licensed gaming facilities, allowing them to increase smoking areas on gaming floors (up to a 50% maximum) if revenue per slot machine in smoking areas equals or exceeds that in non-smoking areas. Facilities must request quarterly revenue reports from the Department of Revenue to justify such increases and ensure compliance. This directly affects casinos and gaming venues operating under Pennsylvania's licensing rules.
