Well, this is a dumb question but I must ask. I received my Blu just a day ago. It seems to be working fine. I noticed on the box it came in it said, "no nicotine in this box." But I did not order non-nicotine. The sample kit had several flavors. They have small stickers on each saying, med, high, low. So does that sticker indicate the strength or did I get non-nicotine? I feel like such an idiot for asking this, but I cannot find my answer anywhere else.
