Pre-legalization, standard prices were $50-60 per eighth of weed.
Now that same sh!t is down as low as $10/8th. Well, I occasionally splurge and go for the $25 stuff.
And that's AFTER taxes.
So that whole argument about legalization making everything more expensive is absolute horseshit. Take the black market away and prices drop.
EDIT: sorry, looked back, realized you were saying legal AND taxfree. For some reason, got it in my head that you wanted back to pre-legal days. Either way, it's worked out positively. And the government will step on anything anyone else would. Always the pinch.
