The age to buy tobacco products in Illinois will officially be raised from 18 to 21 next week. Supporters say the move is aimed at stopping young people from starting a bad habit.

Tobacco sales in Illinois will soon be off-limits to anyone younger than 21 under a law signed Sunday by Gov. J.B. Pritzker.

The Illinois Senate Thursday approved raising the legal smoking age from 18 to 21. All eyes now turn to Gov. J.B. Pritzker, who has yet to say where he stands on the idea. 

For decades, public health advocates have pushed for limits on smoking. They've included warning labels on products to limits on where someone can light up, all of which have helped bring down smoking rates. But in Illinois, a push to raise the smoking age has repeatedly failed to become law. We took a look at this year's push, and what chance it has at becoming law.
