Drug Testing: How Long Does Heroin Stay in Your System

Reading Time: 3 minutes

You didn’t click this story to be told that heroin is bad for you—or that you should stop doing it, so let’s just get right to it.

These aren’t the kinds of stats that the National Institutes of Health publishes, but the following figures are commonly accepted—with a few variables such as body weight, metabolism and how heavy your drug use has been.

How Long Does Heroin Stay in Your Saliva and Blood?

Heroin is detected in the blood for a relatively short period of time, generally less than a day. It can be detected in the saliva for longer—about 1-4 days.

How Long Does Heroin Stay in Your Urine

This is the area where you see the most discrepancy. Generally, heroin can be detected in urine for 2-4 days, but some sources caution that, for heavy users, it can be found for as long as a week to 10 days on a drug test.

How Long Does Heroin Stay in Your Hair?

The short answer is 90 days. Standard practice is to test the 1.5 inches of hair closest to the root. Because hair grows at a rate of about a half inch a month, that equates with about 90 days.

If you’re bald, things get tricky, because body hair is then tested. While there is no conclusive evidence, some sources say that body hair can detect drug use that occurred as long as one year ago.

Can You Beat a Drug Test?

If you have enough advance warning, blood, saliva and urine tests can be passed by abstaining from using heroin. You’ll also find plenty of chatter on the internet about using someone else’s urine sample, but it’s fairly difficult to pull off.

You’ll also find advice about adding bleach or other cleansers to urine. A trick like that will be detected.

You may also come across shampoos that claim to clean the hair of any traces of heroin. The truth is that drugs don’t coat the hair, they are found within the hair shaft and cannot be washed away.

Are you a casual Heroin User?

You might use Heroin every once in a while because it makes you feel good, but you may be surprised by the effects of snorting Heroin.

A Better Way

You’re taking huge risks every time you use heroin—and your employment is actually pretty low down on the list of concerns. More troubling is that, these days, you never know exactly what you’re injecting, smoking or snorting—which makes an overdose a very real risk. There’s a better way to live than trying to beat drug tests and bad heroin.
