Ouch.

Most of the veterans here will tell you that the niacin technique is a myth and won't help you rid your body of thc.

Most all of us will tell you that drinking an abundance of liquids in the days before your test doesn't nothing to eliminate more thc.

The thc that you lose through sweating is miniscule.

Your scenerio is scary. Are you a daily smoker? 5'7, 200lbs and smoked yesterday... Yikes.

I am a daily smoker and I had to do a pre-employment drug test last June. I quit smoking and found this forum. I couldn't pass with any dilution at 14 days, but I could at 21. I must have had heavy amounts of thc in my system!!

It is usually recommended to stop exercising a couple of days before the test, so that's soon. Get a home thc test and see if you can pass using the dilution method found in the sticky at the top of this forum. If you can't, seriously consider subbing and read the substitution sticky. Practice and you'll be ok.

Best of luck!!! :hippy:
