When we say the words ‘drug detection window,’ we are talking about the amount of time it takes before a drug can no longer be detected in your system. There are a number of different factors that can impact the detection window including: the type of drug, the individual consuming the drug, the type of test and the frequency of use.

Urine Drug Testing
Urine drug testing is by far the most common method, and it used by all drug screening facilities. It casts a wide net, meaning that it can test for a number of different drugs including marijuana, heroin, oxycontin and other painkillers. Detection times can range depending on the drug, but it typically picks up on new drug use within the last 24-72 hours. Marijuana however, can be detected for up to 30 days if the subject is a frequent user.
Oral Drug Testing
This is the second most used form of drug testing and it can detect drug use within the previous 24-48 hours. The thing that employers like about oral drug testing is that it is automatically a direct observation procedure. It is very difficult to doctor or manipulate the results of these tests because the specimen is collected by a professional.
Hair Drug Testing
Due to legal restrictions and other factors, hair drug testing is the least popular form of drug screening. Even though it is unpopular, it is often the most effective. It can detect drug use as far back as 90 days and similar to oral testing, it is very difficult to manipulate these tests. If a subject decides to shave his/her head, a collector can take arm or leg hair as an alternative.
Depending on the nature of your business, you might want to consider using all types of drug testing for employees and potential employees. DOT regulated companies need to be aware of the legality of using these specific types of tests and National Drug Screening can help!
