I had some hash brownies (4 separate times) in amsterdam and i was wondering how long it will last in my hair follicles? i'm not a normal user. thanks

Drugs in Hair: Until your hair is cut past the growth from the time you ingested the hash. It does not dissipate from hair. It remains positive in your hair as longs as the hair is around.
