â??How long does marijuana stay in your system?â?ť you have to realize that itâ??s very unlikely that youâ??ll be able to get a usable answer. The most common period of time is anywhere from 3-30 days, depending on your metabolism and the amount of marijuana that youâ??ve smoked. This is unfortunate, since it means that while most drug tests can only turn up evidence of other drugs if youâ??ve been taking the drug within a few days of the drug test, marijuana could still be detected in a urine test up to a month after the last time it is used.

How long does Marijuana stay in your system?
zebu111 Reviewed by zebu111 on . Hair test Hi I was wondering just how the hair tests worked for marijuana. Hypothetically speaking, if a person smoked for the first time ( lets say last week) I'm wondering how long it will take for them to get clean. What I mean is if a lab needs the first 1.5 inches of hair which takes on average 90 days to grow how long will it take for none of their hair to show traces of THC? On average how long will it take the hairs on their head and body to show no traces of THC while growing? Rating: 5
