So what's the alternative? Have employees in an altered state attempting to do their jobs? Recreational drug users love to play the victim because they don't think their use negatively affects anyone, much in the same way a drunk driver thinks they can drive fine while drunk.

I work in a manufacturing facility, so very much a safety sensitive environment.

We are required to be drug tested as part of a pre-employment screening and potentially after incidents. The cool thing is it is part of our collective bargaining agreement that they are not allowed to screen for THC with a urine sample because of how invasive it is.

Mouth swabs are more expensive, but also only screen for THC within 24 hours. I'm sure that number is up for debate as well, but it is a far cry from the 6-8 weeks you can potentially test positive for with a urine screening.

Place I work explicitly told me they don't drug test. They understood what you do on your time is your business. So long as you don't come to work under the influence of anything.

Your job is paying for your health insurance. I’m honestly surprised they don’t test for more. The American health care system is ridiculous.

It’s only legal if it’s required for your profession (like in aviation), it might threaten life or mean death (for instance a taxi driver), there are big non-lethal risks connected to the employee’s work (no idea on this one)

As it’s a medial procedure so it has extra rules regarding that and the shielding of medical records from the employer.

The company also have to discuss this with the workers show stewards before they choose to do testing, and other forms of action needs to be taken and be ineffective before you can move on to testing.

Not all jobs drug test in the USA, if you get onboarded for a job that does eventually test, refuse, and if they have an issue with it, decide if it's worth your time to fight them over it or walk away and start the slow job hunt grind again. You don't have to work for a company that tests, that is ultimately a choice you make. A common issue however with finding jobs that don't drug test is that you're going to be footing your bills for all standard healthcare plan costs and such. No biggie if you value your urine privacy!
