Hair follicle drug tests can determine whether a person has been using certain substances within the past 3 months. However, these tests cannot pinpoint the exact date of drug use because hair growth rates can vary widely among different people.
Although hair samples undergo a two-step testing process, they are not 100 percent accurate.
Factors that can affect the concentration of drug metabolites present in a hair sample include:
the structure of drug compounds
the quantity of drugs a person has consumed
how much a person sweats
the amount of melanin (dark hair pigment) in a person’s hair — certain drugs bind more readily to melanin
bleaching or coloring the hair

No. As long as you did not do any more than a bump. If you are having a drug test, why are you doing drugs? Don't forget, if you are working, your employer can order a drug test at anytime on any employee. Is it really worth losing your job? Keep off the drugs.
