The latest version of the bill bans smoking in most public places and most workplaces. There would be a few exemptions, including cigar bars, tobacco shops and actors portraying smoking on a movie set. But it will not exempt smoking in bars, which is a change from the House version of the bill.
Backers say the legislation protects employees and patrons from the dangers of secondhand smoke.
If the Senate approves the ban, the bill will have to go back to the House for a vote, since new restrictions were added Wednesday.
The bill only passed the House after the exemption for bars was added. With that change, it is unclear if the bill will garner enough support in the House to keep it alive.
