Why is tobacco not illegal?

Tobacco is not illegal because it is widely used and culturally accepted in many countries around the world, including the United States. Additionally, the tobacco industry is a significant economic player, and the governments of many countries rely on the taxes generated by tobacco sales for revenue. Despite the well-documented health risks associated with tobacco use, it continues to be widely used, and as a result, its legality remains largely unchallenged. However, many governments around the world have implemented measures to regulate and reduce the use of tobacco, such as warning labels, advertising restrictions, and taxes, in an effort to address the health risks associated with its use.
