Kansas City, Kansas approved a similar measure on a 6-1 vote Thursday night.

Supporters say raising the legal age to 21 will make it harder for younger smokers — including 18-year-olds who are still in high school — to obtain tobacco products and provide them to younger friends and relatives.

The Greater Kansas City Chamber of Commerce is leading the effort to have the ordinance passed in all cities in the metropolitan area.
