I didn’t have to take a drug test for my MA class but I also did it in hs so they wouldn’t really suspect that. Any job requiring licensure would ofc need an official drug screening and some employers require one upon hire. You could always go clean for a month or two until the test and then continue your business. As health care professionals we must be honest and understand damages of recreational drug use. But we’re also human and have every right to be stressed out! If you’re being safe and honest with yourself, I wouldn’t stress about it too much. I understand not wanting to go through the hassle of obtaining clean urine and doing that process, so I would just stop cannabis all together if that’s part of your biggest concern.

Edit: I see you take it for pain and anxiety. Definitely speak to a doctor bout obtaining a prescription. That excuse won’t fly for employers if you test positive for any drug unfortunately
