California is the only state in the U.S to levy a tax on guns and ammunition for the purpose of funding safety initiatives. Revenue is being used to fund efforts such as providing counseling to survivors of gun violence and establishing hospital-based violence prevention programs. The tax of up to 10% on firearms and up to 11% on ammunition is aimed at shifting the responsibility and costs of gun violence back onto users in California. Critics of the tax say that it disproportionately affects those who are least able to afford it.
