You have also presented no evidence whatsoever that drug legalization would add to your tax burden in any way. Everything presented thus far suggests that crime and incarcerations rates would decrease, which lowers your tax burden drastically.
I linked an article in another thread where they're doing drug testing for public assistance in Posey County and saved taxpayer money.
The problem is, "evidence" doesn't exist in large part because almost no one has a testing requirement. They just pay the bills without question.
