You can't unfortunately.
No.
yes
yes, I just went in for my preemployment drug screening and they administered both a urine and hair follicle test
No. They will fail. It usually goes back 90 days.
Any at all.
drugs and there metabolites that show it passed through the body.
all the way
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
Yes, blood carries and deposit THC into the hair follicle. But hair grows 0.5 inches per month so ..for a week or 2 you can be ok. Also a 0.5 inches of hair = 30 days drug history. Ti is there until you cut affected hair.
Yes. Once the hair follicle is clean it stays clean until you use again.
Not very accurate. The testing industry generally accepts that tests are accurate for a 3 month period. After that the hair is considered too old and the results are less than accurate to PROVE that you have taken drugs.
