Brass Knuckles Had Issues With Pesticides.

BK cartridges are clean from pesticides according to the company, but previous versions have failed multiple tests as shown on datdude41510’s Instagram page  He tested Stiiizy as well and all came back clean. Maybe Brass Knuckles has cleaned up their act, but the pesticides were there at one time. Stiiizy came out completely clean in testing. See our list of vape pen pesticides tests for more information.

Consistent across vape cart brands is two things: THC is often weaker than advertised and pesticides are a recurring issue. These are more issues in California where we are than in states with stricter rules like Nevada. Go to Nevada Made Marijuana in Laughlin, NV and the testing is legit and write on the packaging for anything you buy.
