My dad is going through chemo and radiation for throat and tonsil cancer. He is a federal employee, but not currently working during treatments. He’s lost over 50 pounds and I recommended getting a medical card to try during his last weeks of treatment as the symptoms are only getting worse and supposed to peak 2-4 weeks after treatment.
My question is: if he uses the marijuana during treatments with advisement from his oncologist, and then wants to return to work after and stops but is still testing positive, will that cause problems? I know he won’t continue use after he’s feeling better (he’s anti marijuana, calls me a pot head all the time for using it for my PCOS and just doesn’t want that to be a reason for him losing a job).
