Tobacco Age

The legal minimum age for purchase and consumption of tobacco products currently varies between states and municipalities and has changed several times throughout history.

Federal
The federal government currently (as of December 20, 2019) requires a minimum age of 18 for sale/purchase of tobacco products. Legislation is pending, but a federal increase to 21 is expected to become law and take effect in 2020.

Exemptions:
Alaska's possession requirement does not apply to prisoners.

History
Historically, not all states had minimum age laws, and many varied significantly.

California became the second state in the nation to enact a statewide minimum age of 21 in May of 2016, preceeded by Hawaii.

Delaware's age was raised in July of 2019.

Guam raised the age to 21 in 2018.

Maine became the fifth age-21 state in July 2018.

Maryland became the 9th state in the nation to increase to 21 in April 2019.

Massachusetts was the 6th state to enact a 21 law in December of 2018.

Local
Counties, cities, and municipalities can and have enacted their own minimum age requirements, almost all of which have raised the age to 21. Most are in states with a lower statewide minimum age, or are in a situation where the municipality raised the age to 21 prior to the state doing so.
