Why order a drug test for heroin?

A drug test is a procedure during which a biological specimen taken from samples such as urine, hair, blood, or breath is used to determine the presence or absence of drugs in the system. Drug testing for heroin is usually performed for the following reasons:

  • Pre-employment testing
  • Random testing for work, legal, or school
  • Return-to-duty drug testing for illicit drugs
  • Reasonable suspicion or cause testing
  • Post-accident testing
  • Follow-up testing for medical reasons

In some organizations. drug testing is required for all employees. In fact, both federal and non-federal workplaces are allowed by law to have drug testing programs in place. Still, any workplace drug-testing program should comply with applicable local, state, and federal laws.

There are several reasons why drug testing might be required, such as:

  1. Compliance with federal regulations, insurance carrier requirements, and/or with customers .
  2. Compliance with reinforcing the organization’s “no drug use” position .
  3. Identification of employees with substance use disorders and referring them for assistance .
  4. Establishing boundaries and rules for discipline or firing .
  5. Improvement of safety.

Types of heroin drug testing

Heroin can be successfully detected in the body of individuals who take the drug, using the following types of drug tests:

1. Hair follicle tests to detect heroin

Hair follicle testing is an effective way to detect heroin after many months since last use. Many drugs, especially heroin, remain in the hair for up to three (3) months, or longer (depending on the length of hair sample).

2. Urine tests for heroin

Heroin is detectable on a urine drug test from several hours after use up to 2-4 days after use. Heavy users can fail a drug urine test for as long as seven (7) days after using heroin.

3. Blood tests for heroin

Blood tests are another way to detect heroin drug use, but are considered to be the least reliable . Many opiates, like heroin, leave a person’s blood stream within 6 hours of dosing and are difficult to detect within this short window of time.

4. Saliva testing for heroin

Heroin has a short detection time when using saliva or oral fluid drug tests. After taking heroin, the averge detection period ranges from 5 to 48 hours.

Heroin detection in the body

Heroin stays in the body for a short period of time. It’s half-life is somewhere around 10 minutes, and it’s out of the the user’s system within 3-4 days. However, heroin may still be detected in the user’s body even after this period via drug test. The detection window for heroin greatly depends on the type of drug test.

  • Blood testing usually only detects use of heroin for up to 1 DAY after use.
  • Urine tests can detect traces of heroin from 1 – 4 DAYS after use.
  • Hair follicle tests may detect levels of heroin for up to 90 DAYS or longer.

Other factors that influence the detection period of heroin include:

  • the amount of heroin used
  • frequency of use
  • how long you have been abusing the drug
  • level of heroin purity
  • physical tolerance to heroin

Heroin might still be detectable in the user’s system for longer periods in cases such as:

  • Taking higher-dose of heroin
  • Daily heroin use or multiple use per day
  • Slow metabolism
  • Use of additional substances(medications) that cause slower heroin processing

Heroin cut-off levels

Different types of drug tests have different cut-off levels which vary by drug. A heroin cut-off should be optimized to detect the presence of the drug in any biospecimen or sample, but should also minimize the number of false positive results by being too sensitive. Here are some basic guidelines for heroin cut of levels for urine and hair screens.

1. Urine cut-off levels: The cut-off level for initial urine tests for heroin is 2000 ng/m.

2. Hair cut-off levels: The standard hair screen takes 1.5 inches of growth as a sample for testing. The detection period of 1.5 inches hair sample is approximately 90 days. If the persons hair is shorter than 1.5 inches, this detection period will be shorter as well.

NOTE: A negative test result doesn’t always mean the person has not used heroin or that s/he is drug free. In some cases, the drug may be present in the body with a concentration lower that the defined cut-off.

Positive drug testing for heroin

If your heroin drug test comes back positive, there are several things you can do:

  1. Ask if you can retake the test.
  2. Require the laboratory to retest your sample again.
  3. You can ask for a hair drug testing sample to be performed (usually you have to cover the costs).

Laboratories have the highest credibility when it comes to confirmation of urine samples for drug testing. Positive test results that indicate the presence of heroin might have to be double checked because of certain foods, food supplements, beverages, or medicines that may affect the testing results.

Decriminalization/legalization is necessary, it needs to be backed up with public health announcements explaining exactly why it is needed. Its not in any way condoning the abuse of addictors, it is done bc the alternative, the drug war, has made things infinitely worse on almost every level, to include making drugs abundantly available to any & all that wants them. We need to pull LE out of the drug biz – that will free up a lot of resources currently chasing their collective tails. When the laws create more harm and cause more damage than they prevent, its time to change the laws. The $1 TRILLION so-called war on drugs is a massive big government failure – on nearly every single level. Its way past time to put the cartels & black market drug dealers out of business. Mass incarceration has failed. We cant even keep drugs out of a contained & controlled environment like prison. We need the science of addiction causation to guide prevention, treatment, recovery & public policies. Otherwise, things will inexorably just continue to worsen & no progress will be made. Addiction causation research has continued to show that some people (suffering with addiction) have a “hypo-active endogenous opioid/reward system.” This is the (real) brain disease, making addiction a symptom, not a disease itself. One disease, one pathology. Policy must be made reflecting addiction(s) as a health issue. The war on drugs is an apotheosis of the largest & longest war failure in history. It actually exposes our children to more harm & risk and does not protect them whatsoever. In all actuality, the war on drugs is nothing more than an international projection of a domestic psychosis. It is not the “great child protection act,” its actually the complete opposite. The lesson is clear: Drug laws do not stop people from harming themselves, but they do cause addicts to commit crimes and harm others. We need a new approach that decriminalizes the disease. We must protect society from the collateral damage of addiction and stop waging war on ourselves. We need common sense harm reduction approaches desperately. MAT (medication assisted treatment) and HAT (heroin assisted treatment) must be available options. Of course, MJ should not be a sched drug at all.

“Prohibition goes beyond the bounds of reason in that it attempts to control a man’s appetite by legislation and makes a crime out of things that are not crimes. A prohibition law strikes a blow at the very principles upon which our government was founded.”

Hi mrm42. You speak the truth! But, laws and politics don’t seem to work this way. We have the example of Portugal, where the personal use and possession of all illicit drugs was decriminalized back in 2001. This drug policy has been cited as proof that softening drug laws does not increase illicit drug use or the consequences of drug use.

The U.S. War on Drugs is clearly failing by far…

Hi M Lewis. You can buy at-home drug test kits online. There are many companies who sell and deliver them. Otherwise, you can ask your doctor for a drug test to be performed in a laboratory.

Hi Danny. Poppy seeds that are added to cakes, bagels, and other pastries, can contain traces of opiates and cause a false positive opiates. Download our FREE e-book to learn more on the causes of false positive and what to do: http://addictionblog.org/ebooks/the-definitive-guide-to-drug-testing/

So if heroin doesn’t show up but there’s a ton of morphine that shows up and you know that someone has used? Is there a way to tell how much was consumed by the amount of morphine found in their system?
