WORST DECISION!!

So I had an interview and well they never called me so i thought I didn’t get the job and we’ll ! TURNS OUT I DID and well I was on vacation and i didn’t know and I got with my cousins and they were smoking and i also hit the wax pen 3 times (without knowing I got the job) and now I need to take a drug test 😭 and I don’t smoke this was literally my 2nd time . How long will it take to leave my body ? And what can I do?
