Tobacco 21 or T21 is a fairly new tobacco control effort in Arizona however it is gathering momentum. Last Year on 06/02/2016 Yavapai Anti-Tobacco Coalition of Youth (YATCY) encouraged the Cottonwood City Council to pass an ordinance to raise the age to purchase tobacco products and e-cigarettes from 18 to 21. Cottonwood is Arizona's 1st Tobacco 21 Community!
Other efforts in Arizona are on-going.
The reasons for Tobacco 21 are numerous.
Here's the national Tobacco 21 website (Tobacco21.org) with more information including a state-by-state analysis of Tobacco 21 status/achievements:
