So I'm new to this whole e-cig thing I started because I go for surgery in a few months and wanted to quit or at least be able to have something to tide me over in the hospital. I bought the Joy e-cigs (Joy Electronic Cigarette Starter Kit) because they were fairly cheap and seemed to have everything we needed for my boyfriend and I. I however, have found that they are hard to find information about and the same goes for cartridges. I want to try different flavors as I have a sweet tooth and have always enjoyed trying the different things Camel came out with. I just don't know if the same cartridges will work if I re-fill them or if there are different cartridges I can just buy to make things simpler. I do know it is a three piece cigarette. The battery, atty, and the cartridge. If anyone can help me it would be most appreciated and welcomed!
