How long do opiates stay contained by urine?
Answer:
depending on how much you do, wut kind of opiate, perc, vic, o.c, opium, heroin, body shipment, metabolism, body fat, potency........ but usualy a hours of daylight or two
The detection limit of the initial peak is 300 ng/ml, with a sensitivity of 20 ng/ml. This is sufficient to detect heroin use for approximately 24-48 hours post dose and codeine for somewhat longer. Positives are confirmed on GC/MS at a cutoff plane of 300 ng/ml.
