Got my first ua today have been struggling with fentanyl use and also smoking weed.
I told my probation officer I have been struggling and I am getting on the sublocade shot in a week or 2. I used baking soda 3 spoonfulls at 11 am and drank water until I had to be there at 2. I took the drug test at 2:30. I didn’t get my results right there because they send it to a lab. Opinions? It will be my first time failing one if I do, so what should I look forward to?
