If you are an employer who performs drug tests, you’ve likely come to rely on them to identify problematic or troubled employees. Drug tests can also serve as an important tool in the hiring process, as they allow you to pass on candidates with unacceptable habits. Unfortunately, drug testing has its limits. In order for your drug testing to serve an effective purpose, you must schedule it with frequent regularity. Otherwise, drugs will simply evaporate from an employee’s system. In order to judge a test’s effectiveness, it also behooves you to know the limit of a drug test time table.

If you schedule tests carefully, you can effectively capture evidence of any drug in the system of a user. Certain drugs are easier to detect than others, however, thanks to length of time they remain in a person’s system. For each drug, we’ve identified the upper limit of its presence.
