Everything I ordered for myself from vapor4life is 0mg. I order some low strength 4mg and 8mg for a friend, but almost any place you can get juice you can get it in 0mg+. There are a few out there that only sale the higher stuff nothing below 24mg, but those are rare. So far I am liking my pre-filled cartos, but once I get more into it, I will probably be filling my own cartos. Some of the prefilleds I order only come in 0mg, but V4L is running low on some of their stock.
