Say I've been clean and I have a drug test at 3:30pm EST tomorrow and I decided to snort some dope in the morning, would it be in my system that quick if I took a urine test just hours after dosing on dope when I've been clean?
can it not wait? and no...I'm not supposed to answer this, but no...you will fail...and they'll know from the 6-MAM in your system that it's heroin and not morphine...
