Results: Daily Debate: Should the U.S raise the legal smoking age to 21?

Hawaii's governor on Friday signed a bill raising the legal smoking age statewide to 21, the first U.S. state to do so. The law takes effect on Jan. 1, 2016, and will also ban the sale, purchase or use of electronic cigarettes for those under the age of 21.

"Raising the minimum age as part of our comprehensive tobacco control efforts will help reduce tobacco use among our youth and increase the likelihood that our keiki (children) will grow up to be tobacco-free," Governor David Ige said in a statement.

Most U.S. states set the legal smoking age at 18, while a handful have set it higher at 19. Some cities and counties, including New York City and Hawaii County, have already raised the smoking age to 21.
