Hair Sample Drug Testing – A New Development in Drug Testing

There are many methods of doing drug tests. The most recent method, which is the hair sample drug test, is considered by many as the best test among them. In a hair sample drug test, a hair sample is taken from any part of the body. From that sample the specific drugs used by the person can be detected. A hair follicle drug test can also be done to measure the drug molecules and the specific metabolites that are produced by the drug molecules after it has been processed by the human body. Traces of its metabolites are inserted into the hair follicle by the bloodstream after the drug is processed by the body. Drugs that can be detected using hair drug tests include Cocaine, Opiates, Methamphetamine, Phencyclidine, and Marijuana. A distinct advantage of hair drug testing over the other common drug testing methods is that the samples are more tamper proof and drug use history can be detected.
