You just need to buy a bottle of some flavored e-juice with tobacco or menthol tobacco, not sure which you "smoke". Take the cartomizer (filter) off your Smoke Tip and pry off the white top, it's kind of hard plastic and glued on there. Under that, is a clear plastic ring, take that out too and just throw that one away, you won't need it anymore, but SAVE the white one to put back on. See the white filler looking material inside there? There is where you "drip" the juice into. And remember, slow and long intake on the e-cig for the best results! Good luck! I loaned mine out to my coworker and she's still smoking while using them too. I did too. But think of the ones you are NOT smoking, isn't that wonderful?!!!!! Just stay on this and keep reading up and asking questions and eventually, you won't care that it looks like a "cigarette" anymore, you'll just want the battery to last longer! Best of luck to you and congrats on getting started! I love Smoke Tip just for the fact that their batteries have a lifetime warranty.
Order yourself a couple of bottles of e-juice for back ups, and then later you'll want to order more "cartomizers". You can get into the more complicated stuff like atomizers, cartridges, drip tips, and bigger batteries when you feel more comfortable with knowing what you're doing. This forum has ALOT to absorb!
