A member asked:
If certain drugs is detectable in the hair for as long as 90 days, does that mean the drug is possibly still in my body all that time?
A doctor has provided 1 answer
No. The drug may not be in your body, but it has left its imprint on the dead hair cells which continue to grown in length over time and can be read like a time map of your health.
