not much actually, the hair test is very accurate. don't take it, you might go to jail for all the pot you smoked in the last 10 years, which should be a lot. cause you know you can't pay that fine... drink some milk
Any amount in your system would show up but keep in mind that it stays in your system for 3 months in things such as your hair follicles.
50 nanograms/milliliter in immunoassay screening (EMIT), 15 ng/ml for GC/MS confirmation. Not a heck of a lot.
Pretty much any amount
Nothing.
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.
if you're talking about a hair strand drug test, my understanding is that marijuana can be detected in the strands of your hair for about a year.
no
No, hair extensions are made from the hair of homeless junkies that sell their hair for meth. Using this hair in a drug test would definitely give a positive result.
Simple.... DON'T do drugs - period !
An ounce
Yes
THC, the active component of marijuana, is filtered out of the fat in your body after about 30 days. If you smoked marijuana 3 months prior to a drug test, it should be literally impossible for you to fail the urine test. Actually, THC is filtered out after 28 days. Unless you get a Hair Test. Hair tests really mess everything up. Fortunatley the rareley do that. yeah three months then your completely fine dont worry about it but blood also is bad so yeah urine your fine hair tells every drug you have ever did in your life
it depends on how often, how much you smoke, and if you cut your hair often. they make hair washes that make marijuana undetectable if you have the time/money to order some if needed
No. Drugs stay in the hair for weeks.
It's permanent. That's why Britney Spears shaved her head right before her drug test.
