Drug testing is a big business. From employers who use drug testing as a pre-employment screening tool to parents who want to keep tabs on the well being of their teenagers, there are many groups that frequently use drug testing as a screening mechanism.

Since the mid-1980’s, drug testing has become more and more common. Probably the group that is tested most often is prospective employees. With strict workplace safety legislation and the fact that employees can use dangerous equipment or have access to sensitive information, employers want to be certain that their employees are not drug abusers. With a sample of urine, hair, blood or swab from the mouth, drug-testing laboratories can often product positive or negative results within 24 to 48 hours.

Recently, drug abuse testing has become increasingly common in professional athletics. With the controversies surrounding the use of steroids and other performance-enhancing drugs, athletes are under a great deal of scrutiny. A positive result on a drug test can result in penalties such as fines, loss of game time, or complete dismissal from the team.

Opponents of drug testing argue that it violates a person’s rights to privacy. They hold that even if an employee is a recreational drug user, it does not necessarily follow that his or her work will be affected.  With random drug testing gaining popularity in the workforce opponents say that it can ruin a person’s life.  Even recreational weekend usage may result in the loss of employment if the drug usage is determined with a drug test. Random drug testing is often argued to be testing without any probable cause.
