I've been vaping for about 8 years. Went through Blue (not very good, no smoke) Eonsmoke (pretty good but you have to mail-order them if you live on the west coast. No, one cartridge isn't the same as 1 pack. One cartridge lasts about 4=5 hours of unrestricted-by-surroundings "smoking". Lately it seems as if the batteries aren't as strong as they used to be. Now I live in the pacific northwest, lots of vapor stores. Unfortunately, in Portland they are being regulated as if they were cigarettes. I arrived here because a website from which I ordered seems shady, even though I did receive the product, and I can't get back to their original page.
