It depends on how long ago it was smoked.
If it's more than a week ago, you should be ok for a urine test.
Marijuana does store in your fat cells though, so maybe other kinds of tests could find it.
No but it will still show up in your hair.
If you did not smoke any marijuana, and you have since washed your hair, you will have no marijuana in or on any of the strains of hair on your head, and it will not show up on any drug tests.
No, you must smoke it for it to be stuck in your hair.
nope.
no
You shouldn't have any bad effects if you only smoked once. It's not that serious.
yes
No.
yes, i just passed a hair folicle test and i did smoke 2 hits about 60 days ago.
No. Not unless you shaved yourself bald. Seriously. Once a chemical is locked into the keratin in your hair, it's there forever. Or at least until it's cut off. If a hair on your body can be found, that was growing there when you smoked marijuana, the hair drug test can detect marijuana use from it.
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.
you would get addictive to the marijuana you smoked and then you would never quit because it has nicotine in it which gets you addicted
