Assured At Home Marijuana Drug Test Kit - 2 Pack | THC Detection for Personal & Workplace Use | Fast & Accurate Results

These did not work for me at all. You need 10 of them to maybe get an average guess. I tried 3 and kept getting different results. They come from the dollar tree ($1 store) and in my opinion cannot be trusted. I was using them a few years ack to try to testmyself before getting a job and ended having to use some others I bought online that worked much better.
