pigovian taxes can be described as taxes that exist, but might not exist on paper, so for example alcohol causes an increase in crime which leads to an increase in taxes to pay for prisons and police but that tax might not "exist" as its own separate tax on liquor manufacturers. Understand?To me, sin taxes and Pigovian taxes are a distinction without a difference.right? but you can describe all taxes as "pigovian" with that vague of a definition. cigarettes are taxed because they want people to stop using them and can't generate enough popular support to outlaw them,which makes this a sin tax. Also, marijuana taxes only exist to coerce popular support for its legalization which also makes them a sin taxThat is exactly how cigarette and alcohol taxes are sold. To pay for all the health care costs of smokers and for the toll of drunk driving accidents and alcoholism. That's the Pigovian angle.Sin tax is more for something that is bad for you, like porn taxes, liquor and gambling taxes etc, while pigovian tax is more of an economic term for a tax created out of a social need from something, for example taxing a gold mine to pay for water filtration because they are dumping chemicals in the towns drinking water"Sin tax" is a colloquialism for Pigovian tax. They both serve the same purpose, with very little distinction between them.its more of a sin tax, than a pigovian tax
In recent years, they have also targeted tobacco stores, which is more in line with the "sin tax" angle.

A sin tax however could be on something that has little, to no, negative economic impact at all. Like a pornography tax which although the municipality might use the "porn tax" to pay for road, bridges, or even abstinence classes at the high school. The externalized costs (from having legal porno) either dont exist, or would exist without any correlation to whether or not pornography is legal
