Drug Detection Times for Hair
In the case of
hair drug
tests, it will take around 5 days after drug usage before
traces of the drug can be detected in the hair follicles. This
remains detectable until the hair is cut and drug use ceases.

Drug Detection Times in Urine
|
|
 |
Drug detection times in urine are expressed in the table below
and were provided by a drug screening laboratory.
Please
note that the amount of time that a drug/metabolite remains
detectable in urine can vary and in a small percentage of cases,
users may test positive longer than times shown. This is usually
caused by cases of long-term chronic use, people with high body
fat and/or slow body metabolisms.
These drug detection times are based on urine analysis. Drug detection
times for hair follicle testing tend to be higher, whereas detection
times for blood, saliva and perspiration testing tend to be lower.
