I used on Saturday morn. and it is wednesday and i am pretty sure i passed my urine screen today if that helps. It normally stays in ur system 72 hours
i think it goes out of your system pretty fast (compared to pot or such) -- - but of course dosage counts. if you were taking a drug test i would give more than 1 day for any regular usage. a few days at least - i am no expert tho....
Cocaine or Crack and for how long?
How much a day?
