Drug Test

I am apart of a methadone clinic. I have been going there for about two years and am two years clean off fentanyl but still do coke on and off sometimes. Not much at all - maybe every other month max. I bought some on Sunday afternoon and started around 3:00pm, Sept. 6th during the day and used it until about 10:30. This is the first time I have used it in a little over a month, and didn’t do that much obviously. 8 bumps max. I am kind of freaking out because I have a drug test tomorrow and don’t know if the main components of cocaine will be out of my system in time or not. Like I said, I hardly do any anymore but I’m just scared I’m gonna fuck my progression up at my clinic. Any advice or comments on whether my drug test will be negative or not? I’m sooo scared, hopefully it works out.
