These cartridges look like convenient store blunt wraps the way they are packaged. There is no proof of lab results on the packaging as well. I haven't tried these but I have been seeing negative comments (more than Brass Knuckles) about them for the past few months and I am definitely concerned with what high school students are smoking today. The fact that these are discreet, abundant, and cheap makes it all the more appealing and I really hope there isn't anything harmful in these. If you are smoking these just be wary.
