hey, I know this is old but I've heard that this test is one of the right ones as it cannot be faked.. though I've passed only the urine one at the moment. On the other hand, we all know that any test can be cheated on.. so you never know for sure. When I had to take a urine test for work, we had to buy them ourselves, so I have a lot of urine drug test dip cards samples at home :) I can say that these tests are true and the company I'm working for was satisfied with the results, so yeah. If anyone is interested in, I tested myself on drugs with the help of the test from this site
