I might need to take a drug test in the next few days.

Replace your piss with clean. You will not be observed during the test.

Temp is key weather you use a clean friends, or purchased dehydrated.

(purchase the clean dehydrated urine, is comes with a tube, temp gauge and heaters). Same day shipping available, but you'll be ok with 2nd day it sounds.

Good luck.
