yea, supposedly its 90 days for 1.5 inches of hair.... so if i got tested in lets say 60 days, and my hair was only an inch... it would be a close call... i dunno.  Its hard for me to imagine ANY amount would show... but i still dont even know what it is.   I will keep you posted

When my wife was working on her Masters in material science eng., one semester included work with a Vandergraff Accelerator. Her instructer said some elements that are accumlative in the body, such as arsenic, remains in hair forever. I don't know if there are any elements in illegal drugs that are accumlative. However, I would bet that there are some of the same elements in legal drugs that are in illegal. If so, that would make hair testing very suspect. Maybe even invalid.

as to how much shows up, it depends...as a chemist I am familiar with the half-life of a drug...it breaks down over the course of time...
go online and look up the drug and check out the half-life.

call a pharmacist ..rite aid...folks know..keep calling a pharmacist until one knows

shaving the head won't help..they only need to get a follicle

This site seems to have some information. I don't know how good it is, since it coming from a 'drug testing company'.

I guess you could shave your head. Since body hair grows slower, that may help you pass.

i think six months is a stretch... but i wonder how much will show up... i mean.. does any amount show up?   weird

when I was a dealer in Vegas the casino manager told the five of us he hired that if we had done any drugs in six months..might as well leave since the hair test can tell last six months.

have you researched it?  how do you know? are you sure? 

Thanks man, I appreciate it.

Well I think hair testing can detect up to 90 days like you said and it will detect a single instance.

I am in the law enforcement background process.  I have passed a polygraph and am awaiting the medical and physch tests.   I was at a bar last weekend and believe someone put something in my drink.   I started to realize something was up and just went outside.   I threw up and felt alot of anxiety.   I also couldn't stop clenching my jaw.  These symptoms made me think this was exstacy and now im scared how this might come up in my drug test.   

Does anyone know how long extasy can stay in the hair follicles... for only 1 dose?   or even speed?    I saw on the internet it says 90 days detection time for an inch and a half of hair, but is this for habitual use or a single incident.   

Please let me know if you are aware of this.  This is very frustrating.  Im thinking of just calling my background investigator and telling himi exactly what happened.
