dude i have taken so many drug tests right after weed and opiates and alcohol its rediculous. like probably 7 or 8. just to clarify though, and this is important, how often do you smoke now and it would be two weeks from that last blaze to drug test yes?
assuming you smoke around once a week, i would say give it up now, although i would still give you an 80 percent chance of passing with nothing but water (im not really sure how efficient cardio would be, but it couldnt hurt either).
if you smoke less than once a month, dude get blazed you will pass that shit with ease. i blazed some dank bud and a fatty paddy of opium and then i took a DOT drug test (very strict where my chick had to stare at my johnson while i pissed so that i wouldnt try any funny business). passed. all i did before was drink hecka water.
the hair thing is true, it can be detected as much as 6 months later. however, as far as i know, they only use that on parolees. and i can guarantee that for whatever job you are going for its going to be the basic old piss test.
you gotta remember this system kinda does this shit as a joke. so many people (although i dont burn anymore) smoke weed, and do more too unfortunately. I know multiple doctors and surgeons, and unlimited nurses and other staff that i have or do work with that smoke pretty regularly. some deal in small quantities. and most of these guys are standout medical professionals. like one of those RN/Medics that flys in air ambulances, bariatric surgeons, and on and on.
if you clarify how much you smoke and when your last burn will be before the test i can spark note all this haha.
