They really need to get rid of those drug testers. They read positive for anything. No the polices fault though because they don't know thy don't work either. Also who assumes that flakes on the ground are drugs first and foremost?
Well I can say through personal experience that from the moment they get out of their car, they are looking to pin anything on you, and to get inside your car. I've had a state trooper follow me for 3 miles on the highway (I saw when he pulled off the side of the road, and also read the mile markers to see how long he was following me) and not pull me over. I got off the highway and was very near my house, at a stoplight, when the cop decided that it was time to pull me over. He said that I was speeding on the highway even though he was following behind me the entire time, and did not put his lights on lol. It was 1 in the morning, and it escalated very quickly from him telling me I was speeding (was 72 in 60, not reckless), to him asking me how much I had drank that night, for no reason. Once I told him I had 1 beer 3 hours before when I got off work, he thought that was good enough excuse to make me get out of my car and take a sobriety test (I did the stand on one leg and say abc's). I passed easily, and I will never forget what he asked next. "Ok so how much
weed did you smoke tonight then?" I looked at him and said "what? I don't smoke marijuana." and
that's when he tried to trap me. Basically he said he wanted to search my car... and I told him no, because at that point I felt mad violated. I remember so vividly him saying things like "Hey, I'm just doing my job" and "Well I could just call the K-9" and I didn't crack. Told him "Sir I passed your test, and you don't have any reason to search my car, so nah, you can call them if you want." Then he tried to switch it on me one last time by saying that when I got out the car, he say a plastic weed bag by my foot. I rolled my eyes at him, and opened the door to see a piece of clear tape on the ground where my feet would have been. I picked it up off the floor, and pretty much shoved it in his face saying "looks like tape to me officer". I just got the speeding ticket, and when I tried to tell the judge in court that the officer was profiling me, he wasn't hearing it lol.
I guess what I'm saying is they probably assume anything on the ground is drugs, in hope that they get lucky, and fill their quota. And maybe if they aren't lucky, they make up something.
The drug kits most police depts use are from 1973, cost $2, and are wildly unreliable

Most cops know the tests are unreliable, and are able to turn any test positive or negative depending on whether they want to make a bust or not

Don't let cops search your car.
Yep. Just don't let them, as long is there's no cause.
