Some juice does, others are just smooth as fuck and feel awesome on your throat. I was offered a glass of banana juice at my local coffeeshop once while smoking and it's been my favorite smoking drink ever since.
Water, Dr Pepper, Gatorade, Naked, Chocolate Milk or Beer... Just kinda depends on the day. Right now its chocolate milk
I heard they stopped selling it because the 3rd word country they were exploiting for the vanilla extract was giving them trouble... not sure if it's true though.
