The most common test that hospitals do on their prospective employees is a blood test, which can be far more costly than urine or saliva tests, but are also far more accurate, and a lot harder to fool/beat. Currently the shortest time frame we know of that you can cleanse your blood stream of toxins is two weeks.

It has become a more common practice every year for an employer to require that any potential employees pass a drug screen, and so a law was passed saying that if a drug screen is part of the company policy that they have to notify all potential employees when going through the interview process. There are two sides to every coin, many employers feel as though these policies help protect the workplace from accidents and all associated costs, as well as helping to keep their insurance costs down. But the question of privacy is often brought into play. The biggest claim of opponents to workplace drug testing is that what a person does on their own time when not at work should not be taken into account when a person is up for a position, but sadly, that isn’t the world we live in.

Over the years drug testing practices and methods have evolved, and today are far less expensive then they once were, because of this home testing devices have been mass produced and are now available to the public at a decent cost. The two most common uses of these home tests are people making certain their systems are clean before going on an interview, and parents monitoring their teenager or child’s activities.
