Beer? Probably. There's nothing like kicking back on your porch in the summertime with a few pops and listening to the Red Sox on the radio. Scotch? Vodka? Rum? I'd probably buy less, yeah, but not enough to tear the bottom out of the barrel.
That's not how BigLiquor looks at it...any drop in liquor intake is a drop in their profits and to the extent de-criminalizing the whacky weed decreases that intake, they're gonna be against said legislation (or change in Executive Order).
