I use my mouth. When I jam my
mod in my lungs, it hurts. Once I connected my
mod to my compressor and turned it on until my lungs puffed out like a balloon. It was too hot with no flavor and even after I exhaled, I farted for like days afterwards. At least the farts smelled like Juicy Fruit though. My wife was like "Did you
buy an air-freshener?" and I was like "Yeah, nice huh?" I'm thinking I do it again around the holidays with Apple Cinnamon for that Christmasy smell.
