Forever!
you stay in jail forever
Forever.
No, exposure to the smoke of marijuana does not stay in the hair forever, but duration does depend on the frequency and severity of exposure and frequency of washing hair. What does happen though is, if a person smokes marijuana there are traces of it that reaches the follicles and grows into the hair. A hair sample can be taken from the person and tested and can prove that he/she smoked marijuana.
Not necessarily, however it does increase your high.
If you are older than 18, forever.
EVERYTHING stays on a hair test. Forever.
about 5 minutes
it stays there forever, a bit like how chewing gum stays in your stomach
Well if it isn't permanent it will not stay forever, so you wont be stuck with the color forever. Also it is less damaging and there are vegan options.
well...it never grows in you hair, but if you mean how long can marijuana be detected in the body... its about 3-30days depending on your metabolism
