There used to be insane mob violence and users being injured/dying of contaminated product during prohibition. Legalization with fair taxes soon eliminated that.
Yes there is still some moonshine in the poorest states but the taxes are reasonable enough where most people in the USA buy alcohol legally. Even though more expensive they prefer a regulated product so they dont risk death.
You rarely if ever hear about poisonings or gun battles over alcohol these days thanks to legalization and acceptable tax rates.

“you can’t carry any lovin’ on.”
