How long does E stay in the system?>Could you please tell me the average time e stays in your system, and if it
>can be detected by a urinalysis or blood test, much thanks
The half life of E is about 6 hours, which means that after 6 hours 50% remains and after another 6 hours 25%, so that after 48 hours less that 1% remains which would be pretty hard to detect. Unlike cannabis, it does not get stored in body fat. But with all piss tests, the more water you flush through, the more dilute your urine and the more likely that the concentration will fall below the limit for the test.
