I think it stays in your piss anywhere from 2-5 days. But I also think it depends on a lot of other factors - such as tolerance, metabolism, etc..
I wouldn't. I remember you...Acid dude right? Didnt you tell me one time to stay away from opiates and go outside and take a breath of fresh air? What happened????
Self control brothahh. And nah, I dont have a tolerance at all. I do opiates probably once every month, maybe less. I just always snort an 80 and smoke some buds. Just a nice way to nullify everything.
