Me too, but we are privileged to choose a job according to our preferences. Meanwhile, there are many people for whom it is way harder to find a better job in their life circumstances / places they live. Losing it can easily ruin their lives.
Yeah, I'm definitely aware it's a luxury to be able to turn down jobs and that this sector-specific good job market isn't going to last forever either. I really think we should ban drug testing in the vast majority of cases to protect people who are less fortunate from the ridiculous puritan corporate culture many places adopt.

Even the thin veil of "heavy machinery" isn't really enough: Your average factory worker deals with "heavy machinery" and trash compactors, commonly used in retail for boxes, are the same. Folks employed in these positions in other countries don't have drug tests and do not have bad safety records, so the danger isn't as high as the employer makes it out to be. I think employers should prove that there is either a federal mandate for drug testing the position OR that drug use, even outside of work, affects work.
