Everything You Need to Know About Hair Sample Drug Testing

If you’re an employer or employee who’s heard about hair sample drug tests but aren’t quite sure how they work, this is the article for you. In this comprehensive guide, we’ll cover everything you need to know about hair sample drug testing, from how it works to its advantages and disadvantages.

How Does Hair Sample Drug Testing Work?

Hair sample drug tests are quite different from other types of drug tests, like saliva or urine tests. These tests involve taking a small sample of hair, usually from the scalp, and testing it for drug use. The reason hair testing is so accurate is due to how drugs are metabolized in the body. After drugs are ingested, they move to the hair follicles and bind to hair strands. This means that even after drugs have left the bloodstream, they can still be detected in the hair for a longer period of time.

Advantages of Hair Sample Drug Testing

There are multiple advantages to using hair sample drug tests over other types of drug tests. Firstly, they have a longer detection window, meaning they can detect drug use within the past 3 months. Secondly, hair sample drug tests are much harder to cheat than other types of drug tests. Hair samples are taken directly from the scalp by a professional tester, meaning it’s much harder to cheat or falsify results. Finally, hair sample drug tests can detect a wider range of drugs compared to other types of drug tests, making them a more comprehensive drug testing option.

Disadvantages of Hair Sample Drug Testing

However, there are a few disadvantages to hair sample drug tests as well. Firstly, they are typically more expensive than other types of drug tests like urine or saliva tests. Secondly, hair sample drug tests aren’t necessarily foolproof, and there have been cases where false positives have been reported. Finally, hair sample drug tests are not suitable for detecting drug use that has occurred within the past 7-10 days, as it takes 7-10 days for drugs to grow out of the scalp.

Examples of Hair Sample Drug Testing in Practice

One example of an industry that uses hair sample drug testing is transportation, including trucking and aviation. By testing drivers and pilots for drugs, companies can ensure that their employees are safe and trustworthy. Another industry that uses hair sample drug testing is sports, where athletes are tested for performance-enhancing drugs.

Conclusion

Hair sample drug testing is an effective and comprehensive way of detecting drug use within the past 3 months. With a longer detection window and a smaller chance of cheating, hair sample drug testing is an excellent option for employers who want to ensure the safety and productivity of their employees. However, it’s important to note that hair sample drug testing does have a few disadvantages, including higher costs and a small chance of false positives.
