How the **** can i get this thc outta my system its been over a month n im still pissin dirty?

okay so its been a little over a month probably 32 days. ive been working out constantly, cardio strength training, drinking tons of water daily. i dont get it how am i still positive for thc i have a drug test this week n i told the employer id be clean in a month for sure. im not! what the **** do i do. dont have a bunch of money either for some expensive detox drink. should i do cardio today or not im getting mixed answer from stoner friends telling me working out keeps it in?? i dont believe it. its been many years since ive been off bud n id smoke a few times a day everyday. does that mean its guna take mutiple months or what shitt this is rediculous!
