Drug abuse can also affect the workplace and so strict measures are taken today when interviewing potential employees or staff of a business establishment or a big company. Marijuana is not sold cheap and are hard to come by and so drug addicts are sometimes forced to work instead of just staying at their homes smoking weed all day long. Marijuana drug tests have been practiced for many years in offices since the outbreak of more than a million drug abuse cases in all parts of the world resulting in panic in employers when hiring their staff. Hair or urine drug testing are the common tests done in the workplace since they are the most accurate tests for the testing of marijuana and they also provide a long timeline of drug history as basis of evaluation. The cutoff level for marijuana is 50 ng/ml, this is based on the standards of the international regulating officials which also dictate the cutoff levels of other common drugs abused like cocaine and morphine, which have a relatively higher cutoff level than compared with marijuana. Certain policies must also be considered when being given a drug test. You can always refuse a drug test if you feel that it is given to you unfairly and without proper reason. Employees can conduct marijuana drug test to their employees if they are observed as to be strange in relation to your behavior towards your work or other colleagues and how well you socialize with others in your work. Positive results of marijuana may lead to many negative consequences; for students, the risk for expulsion and for office workers, getting fired is the worst thing that could happen to you after a positive drug test. The reason why so many companies or employers are strict regarding this issue is to keep a drug free environment for all workers and to prevent contamination of drug use inside the workplace. Every month, there are at least a thousand jobless people due to marijuana addiction. They suddenly get unfit to work. With these precautionary measures taken, employers hope to reduce the use of any illegal substance inside the workforce and also reduce the addiction of their employees through random drug tests which are given routinely to cause deterrence to workers who are afraid to get fired from their work. As of today, drug free workplaces are achieved and maintained.
