Bill Overview

Analyzed Economic Effects

2 provisions identified: 1 benefits, 0 costs, 1 mixed.

Bars and casinos need 60% from alcohol/gambling

The law sets a clear test for the incidental exception. An establishment qualifies only if at least 60% of its annual gross income comes from alcohol sales or gambling receipts, or both. If you meet 60%, you can claim the exception; if you do not, you cannot. This affects taverns, nightclubs, cocktail lounges, and casinos. Check your yearly receipts to know where you stand.

Vaping and marijuana count as smoking

The law defines electronic smoking devices, including e-cigarettes, vape pens, and dab rigs. It also defines smoking to include vaping and marijuana use. Indoor smoking rules now cover these products in enclosed public places and workplaces, like restaurants, bars, offices, schools, and public transit. This strengthens indoor air protections for patrons and workers.
