Hair Drug Testing Length?

hair drug testingOkay, so I won’t mock anyone today. I promise. Here’s another customer question:

“How far back does hair drug testing go? Can they trace as far back as a year?”

The short answer is no, they can’t trace back as far as a year. However, they are the most reliable form of home drug testing currently available. Here’s a breakdown of what hair drug tests can do:

- Detect drug use for up to the past 90 days
- Non-invasive
- Requires only a small hair sample
- Can detect many different types of drugs at once
- Highly accurate results
- VERY difficult to adulterate

So, what’s the drawback? Hair drug tests do not detect super recent drug use, meaning use that has occurred in the past week or two. You also don’t give results immediately–you have to send the sample to the lab and wait for your results. Lastly, hair drug testing kits can be on the expensive side.

But all in all, it’s worth it. These tests have a very long detection period and provide a level of accuracy unavailable in other at home testing form.

I hope that answered your question.
