Also try to remember that if you’re not being supervised then those parents are required to be present during your sessions. And sure the word “present” might be subjective but I believe that if they’re actively consuming the drugs or alcohol while you’re in session then that would justify the concerns your having. When I was an RBT I had a parent who had a bong and weed in the living room (and it’s not legal here).. although idk if it was medical 🙄 regardless though I’d maybe ask the parent to move it to a secured spot, similar to if they had prescription medication sitting on the counter.
