Residue Detection THC Drug Test Kit - Rapid Surface Residue Detector, 1 Test

Will this test for THC in the atmosphere and up to how many feet?

Would this test residue from a wall of a room that I suspect someone is smoking in?

I have a smell in my condo that I cant tell if its mold or marijuana. Can this test tell me if the neighbors are smoking marijuana?

Can this be used on hands to see if a student has recently smoked?
