Alcohol testing and drug testing represent basic functions for securing a safe society.   Alcohol abuse and drug abuse represent a significant danger to society.   While drug and alcohol users use alcohol and drugs as recreational pastimes, the fact that a user can kill people as he or she gets behind a wheel and drives is not conscious for the most part.  At work, substance use can cause carelessness and lead to accidents.  An additional rare danger is that the substances encourage letting anger boil over into killing rage.  For the most part, people are not attuned to the dangers of substance use because the instances of bad things happening are relatively rare.   There is a need for society to control abuse for the common good.  The market research study provides insight into market driving forces, assessment of market opportunities, market share analysis, and market forecasts.
