OK this is probably a stupid noob question but here it goes: I just got my Blu Cig in a few days ago and it has worked great I have not had a cig since (except one at a party when somebody offered me one, but I have never had a craving for one). But here is my question, I like the Blu flavors, but my problem is that the nicotine strength is fairly week (the highest is only 16 or 18 mg I believe). Is there anyway to use other cartridges with the Blu Cig battery? And is there any cartridge you can buy that you can put any nicjuice in?
