Tobacco age 21 nationwide
Anyone under 21 can no longer legally buy cigarettes, cigars or any other tobacco products in the U.S.
The new law enacted last week by Congress also applies to electronic cigarettes and vaping products that heat a liquid containing nicotine.
The provision raising the legal limit from 18 to 21 nationwide was in a massive spending bill passed by Congress and signed by the president on Dec. 20. About one-third of states already had their own laws restricting tobacco sales to people 21 and older.
The age limit in both Michigan and Wisconsin had been 18.
