You would be surprised to know how many different researches have been done associated with drug users and drug tests. For instance, there has been a study on what professions are associated with the use of illicit substances more often; thus predicting who are more vulnerable to drug abuse and people in what jobs should be tested more often. Certain types of jobs require more physical strength, more intense and/or are more stressful than others. Monotonous physical motions, odd-hour shifts, overtime and late working hours – all that contributes to a desire to “relax” at the end of the hard day. Easy access to pharmaceuticals considered a tempting factor, so doctors, nurses, pharmacists, dentists and so on – they are all prone to constant drug testing on a regular basis. According to the research results, such professions as waitresses, construction workers, auto mechanics, truck drivers, people involved in food preparation have the highest rate of illicit drug use. Alcohol use showed high in these categories as well. Such occupations as police officers and detectives, teachers and child care workers, administrative support and state clerks showed the lowest rates of both illicit drug use and alcohol consumption. But then again, these professions are the most targeted among employee drug testing rules and regulations because these people deal with children, or are dealing with dangerous every day situations. And the last, but not least, – the Federal government workers; there is absolutely no toleration for any positive reading for any type of drug tests, so people working in that field tend to say “no” to everything but their job. So, depending on what you line of work is, you can either expect to be tested constantly, or just barely – the research information can be used both ways, for employers and employees.
