Hair Drug/Alcohol Testing – The Most Reliable Drug and Alcohol Testing Method

This is where drug and alcohol testing is of great importance. By conducting a drug and alcohol test, a person positive for these illegal substances would be detected and then necessary actions can be undertaken before he can cause accidents or commit a crime. Several methods of drug and alcohol tests have been developed. Among the following are the urine drug test, blood drug and alcohol test, breath alcohol test, and the hair strand drug testing / hair strand alcohol testing. Positive results obtained using the first three methods (urine, blood, breath) would only indicate the use of these substances only in the recent past. It cannot detect drug/alcohol dependency or drug/alcohol use history. This is the good thing about the recently developed hair strand drug and alcohol testing. With this method, drug and alcohol use history can be detected. This, among many other things, is one distinct advantage of the hair drug/alchol test compared to the other methods.
