Tobacco control is all about discouraging people from using tobacco (like cigarettes, cigars, chewing tobacco and other smokeless tobacco products). It's a way to keep people healthy and reduce the number of people who get sick or die from using tobacco. To do this, governments, businesses, and groups all around the world work together to make it harder for people to get tobacco, pass laws to make tobacco less appealing, and make it easier for people to quit smoking. This can include things like banning smoking in certain public places, adding extra costs to buying tobacco (like taxes), and running campaigns to educate people about the dangers of smoking.
