Me and friends like to flavor our mids that we buy, for a bit of taste, and if anyone wants to buy our stuff we could make a bit more on the buck. They do it with Kool Aid and a bit of sugar. Even though it DOES taste really good, I keep telling them they're shitting up their lungs too much. I've only flavored mine a few times, but it was with some Black flavored Tea made from a Tea Bag, so no sugar
