Help!! I have a job interview tomorrow and i might be drug tested?

-So I have an unexpected job interview tomorrow and there's a possibility that I might be drug tested, I dont usually smoke canabis/weed but about 3 or so weeks ago I took some at a party. Is 3 weeks long enough for the THC (or whatever) to get out of my system? I heard running or eating oranges can help? Is this true? Another mate of mine told me to drink alot of Berocca? How or what can I do to prevent getting a failed result?







P.S , pls dont lecture me about not smoking weed because I dont do it often and after tomorrw I think I'll be put off it for life.Nothing you eat or drink is goung to get it out of your system any faster. Either you will pass, or you won't.



But, most employers do not drug tes as part on an interview. They drug tests just before extending an offer.I wouldnt stress over this. The drug testing usually comes after the extended offer (interview, etc).
Dont put it off your life. thats dumb. Weed lasts in your blood 30 days. urine 7 days. Water + a lot of sweating gets it out to. Dont quit tho thats dumb.
