It is a common practice to conduct drug screening not only among employees but also before hiring them. It is wise of you to come up with this solution before things get out of hand. After all, you will be held responsible in case of an incident of unruly behavior at the workplace. But before you conduct any such tests, it will be better if you attain proper information about it by your pathologist. Ask him about the kind of tests that can be done and plan things accordingly. You must also be aware about the type of drugs that you want to get screened. This is mainly because the trace of each drug varies in different forms. Certain drugs stay longer in one’s urine than in the blood and vice versa. The pathologist will be able to guide you about what is the ideal test for a workplace.
I would suggest that an alcohol test will be pointless as its traces are visible in one’s urine for up to 80 hours. When you conduct such a test, your employee can easily claim that he had some wine with dinner that’s why the traces. Also, certain companies allow consumption of beer during lunch. But there are a number of drugs which leave a
lasting effect on a person’s senses for hours at an end. At such the time, the excuse of its consumption a night back does not work. You must make it clear that drug consumption is unacceptable on working days even after working hours. Along with this, its consumption is illegal in a majority of states.
It will be advisable to conduct any such tests towards the end of the week before you close for the weekend. This is because on an average, drugs are visible in the urine as well as blood for three to four days. If you do it sooner, the person will claim that he attended a rave party on the weekend and justify his actions. In states where marijuana and hash are legal, you can’t object if results show its consumption. At such a time, you can mess with the minds of your employees. Come up with a rule according to which if results show drug consumption three times, then the person will be fired with immediate effect. By doing so, you will not need to announce the results and will instill fear about random drug screening among employees. And majority of times it works. Also make it clear to your employees that if they are suffering from a hangover of any kind, it is better to stay at home instead of risking their job.
