so got a really good job interview went well ill be hired if i pass but i just got out of a HEAVY bender using coke just 2 days ago. I know it only stays in urine for 2-4 days but im not sure because i was heavily using so might still be in my system for longer. Not sure what to do here any help is needed!
my boyfriend is clean is it smarter to use his piss? im scared they will know because hes the opposite gender, or if they have to watch me piss, or just fucking up temperature. I ordered a piss test at home so ill check before i go in for the test but any last resorts ?
