Can we not agree that a Friday night is incomplete without some action Drug Impairment Test. Piercing through the laughter that abounds as you hang out with your friends, you see those flashing blue and red lights; a cop is doing tests for impairment after making a minor stop. So, what goes on in these stops?

Drug impairment testing is designed to keep unsafe drivers off the street. Officers use a standard field sobriety test or a breathalyzer to hunt for signs of intoxication. But wait, there is more than meets the eye here. Different compound, be it alcohol or marijuana, needs distinct evaluations.

When in entirety, Standardized sobriety tests sound like scenes from a circus. Picture someone taking the heel-to- toe straight line walk. Even without drinking some individuals would fail – not everyone’s born to walk a tightrope, right? These may sound easy but gases such as keeping balance, finger to your nose, or tracking tip of a pen with your eyes can trip people under pressure

A step ahead and we have chemical testing. Breath, blood, or urine – these play like detectives for drugs. Breath, much like speed dating, is fast but only detects alcohol. As intricate as it can get, blood testing yields more accurate results and goes on to test for many drugs. Urine testing is more about testing your past than current behaviors.

Drug testing methodologies evolve with tech. Saliva tests and other new methods promise faster, accurate, and less intrusive tests. Still with every new method ethical and legal questions arise.
