I smoked everyday all day when I was younger, then I got caught and was given probation with random drug testing.
My first drug test I took I was around 10-14 days clean and I passed. My PO said, "okay you're now clean and if it comes up
positive from here forward you're going back to jail." I know everyones body is different but I would think you'll be fine
and will pass.
Best of luck to you.
