Smoking age

The smoking age is the minimum legal age required to purchase or use tobacco products. Most countries have laws that forbid sale of tobacco products to persons younger than certain ages, usually the age of majority.

Cannabis age.
Since 2012, various jurisdictions throughout the world have legalized cannabis for recreational use. In Uruguay and cannabis-legal jurisdictions in the United States, the legal age to possess or purchase cannabis is identical to the tobacco purchase age (18 in Uruguay and 21 in the United States). In Canada, the legal age to possess or purchase cannabis is 19 in all provinces and territories except Alberta (18) and Quebec (21). There are therefore three Canadian provinces (Manitoba, Quebec and Saskatchewan) and two territories (the Northwest Territories and Yukon) where the age to purchase tobacco is lower than the age to possess and purchase cannabis, and one province (Prince Edward Island) where the tobacco purchase age is higher. Prior to December 2019, when the United States raised its tobacco purchase age to 21 in all states and territories, several U.S. states had tobacco purchase ages lower than their cannabis possession and purchase ages.
