It's all a test. It was designed this way to weed out the unwanted workers. If I have a multi million dollar company I'm going to run it how I choose. Just like how people have the right to choose to not to work for that employer. I wouldn't want to work next to an addict and I wouldn't make anyone else do it. There's a risk factor involved for both parties. I would be ok with weed. But I would still have an pre employment drug test for drugs and alcohol. An alcohol etg test will determine if they have consumed alcohol in the last five days. If they have, then they are starting at a lower pay than other people starting on the same day.
Just stick with microdosing lsd or psilocybin. It's harder to test for.
