A roommate I had in Boston had a gravity bong filled with dill pickle juice...I think he used Manischewitz. The juice was full of peppercorns and chunks of garlic, so it was a total deli experience if the smoke was good.
Don't get me wrong, I've been known to take a few sips of pickle juice when the jar is empty before throwing it out
But using it as a chaser? Wouldn't the acid just cause it to burn?
