Yeah, I have to get drug tested a lot in my career and have an Adderall prescription. Firstly only one employer has even attempted to drug test me themselves because what they need is to know anything I test positive for is prescribed. Secondly that one that bucked the wisdom of others (it was a job placement agency) fucked up royally by kicking me out as I tried telling them that legally since I can prove I have a prescription for it they can’t reject me for it (this is why most don’t want to know, it opens liabilities). In their parking lot I reported them to the EEOC who declined to sue, but told me I had a case and I was allowed to. No justice here though, I’d gotten a different job by then and didn’t care enough to sue for a job I never wanted
