HELP! drug test

ok, so I was smoking 5-6 days a week, only like 1/3 of a joint each day. I stopped about two weeks ago and need to pass a drug test. I tried the Certo method at home. did not work. I have to take it in two days and I need to pass. It is for pre-employment. I exercise regularly but should I hit the sauna and sweat as much as i can out? should i hydrate a lot the next few days? need help. it is a urine test at lab corp too
