Sin taxes are good. You may consider them regressive, but perhaps they should be.
Overwhelmingly, the ones with addictions that cause severe problems are the lower socio-economic... cause or effect, you decide, not here to argue that.
If we make alcohol harder for them to afford, is that a bad thing?
Also, the amount of trouble/expenses caused by alcohol related incidents, which the state often flips the tab for, justify it as well... including increased health care costs.
Alcohol, cigarettes, dip, etc... they all have heavy taxes applied. Adding 9% is just adding to what was already there.
