Is this Unsafe Medical Cannabis?

[Lysergaman]

I’ve had a med. card for years now for my immunodeficiency, but the weed from my latest delivery was different than I’d ever seen before. The weed was super cheap (more than I’d ever seen) it came in a plastic baggy and it was all different colors from a couple light brown buds, to normal looking, and dark green almost black in some cases. Inside the bag was a nug that almost looked like hash. It was dark, hard, and chipped when I pressed it. I threw it in the mason jar with everything else, but with my immune system I’ve begun to worry about fungus or something. I was using a verified vendor that only dealt with medical patients from WeedMaps and they had a decently high rating, so I assumed they’d be trustworthy. I would really appreciate any answers, im not sure what to do!
