Are Mario, Supreme, and Exotic Cartridges Safe?

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. PS: I would never smoke these.
