Will Heroin Show Up on a Drug Test?


One of the most highly addictive substances known today is still a subject of controversy.  Heroin has made headlines worldwide and has been known as a notorious and indiscriminate killer.  This potent opioid is normally injected by the user, however, it can be inhaled or snorted as well.

Heroin’s long term and short term side-effects have been well known as thousands of individuals have lost their lives due to overdose and other complications.  During its early days, however, heroin hadn’t attained the notoriety as it has today.

A Heroin Addiction resource published by The Recovery Village reports: (Heroin) was first marketed by a pharmaceutical company in the late 1890s as a cough suppressant.  They go on to mention:

It was also thought that heroin provided the same medicinal benefits for pain relief as morphine without the side effects associated with morphine. However, when the overwhelming addictive nature of heroin was recognized by physicians and the government, the medicinal use of heroin was outlawed in the United States in 1932. 

How It’s Made

Heroin is made from the resin of poppy plants.  A liquid-like opium substance is extracted from the pod of the poppy flower.  The substance is then pressed into a rectangular shape and then processed.

The extracted opium can be refined to make morphine, then even further refined to produce different forms of heroin.

A Poisoning Mixture

As a street drug, Heroin is often mixed with other illegal substances.  Because of its powdery white appearance, those who are illegally manufacturing it often cut it with substances similar in appearance.  These include sucrose, baking soda, rat poison, and starch, to name a few.  It’s for this reason that the likelihood of becoming ill due to poisoning is extremely high for those who take street drugs.

 According to John Hopkins University, “Heroin can be anywhere between 3 and 99 percent pure, making the effects of any batch highly unpredictable.”

Illegal Use

Heroin Use is no longer a topic specific to urban neighborhoods and cities.  In fact, it has long since made its way through suburban counties in the United States.  Moreover, those who weren’t at risk for substance abuse years ago are now in more danger than ever.  How so?

According to, Those Who are More at Risk of Heroin Addiction include:

  • People who are addicted to prescription opioid painkillers
  • People who are addicted to cocaine
  • People without insurance or enrolled in Medicaid
  • Non-Hispanic whites
  • Males
  • People who are addicted to marijuana and alcohol
  • People living in a large metropolitan area
  • 18 to 25-year-olds


One of the reasons many believe Heroin has made such a negative impact in society is its accessibility.  In 2019, the DEA Released a National Drug Threat Assessment.  In this document, the DEA states how readily available Heroin has been and continues to be within reach.  The report states:

In 2018, the majority of FDs indicated that heroin was easily obtained at any time. The El Paso, New Orleans, and San Diego FDs indicated heroin availability in their AORs was moderate, meaning heroin is generally readily accessible. The Atlanta, Dallas, Houston, New Orleans Louis, and Washington FDs indicated heroin was more available in theirs areas than in the previous reporting period

Overdose Deaths on the Rise

Heroin’s illegal use has only increased in recent years claiming the lives of many.   According to information from  “Heroin-related overdose deaths increased five-fold from 2010 to 2017”  Today, the overdose epidemic is reaching catastrophic proportions, especially with Fentanyl use on the rise.  As Fentanyl use skyrocketed in recent years, there seemed to be less growth in Heroin overdose-related deaths.

The DEA comments on this point in their report:  “Although heroin-involved overdose deaths may be stabilizing, heroin was still involved in more overdose deaths than any other illicit drug except Fentanyl in 2017. provided this graph indicates the National Drug Overdose Deaths Involving Heroin:

Heroin Effects

As infamous as Heroin may be in society, many are still perplexed about the effects of Heroin or how precisely the drug works.  Some do not have a full grasp of how this substance affects the brain.  When an individual first use Heroin, the human body metabolizes it into Morphine.  When morphine enters the brain, it immediately binds to the opioid receptors in the brain.  Now, pain messages sent from the body through the spinal cord to the brain are now blocked due to opioid use.

The reported rush sensation that many often feel when first using Heroin often depends on how much of the drug is used initially.  Still, many feel the warmness of the skin and possible dry mouth.  This will be followed by feelings of drowsiness which may last for several hours.  Breathing is slowed, and Heart-rate is decreased – many times to a life-threatening extent.  Many times these effects can cause someone to fall into a coma and suffer brain damage.

Heroin Withdrawal

When someone starts to experience Heroin withdrawal, symptoms are typically reported between 6 and 12 hours after their last drug use.  The user will experience extreme flu-like symptoms – similar to what someone would experience with prescription opioid withdrawal.  These symptoms could last as long as a bad case of the flu (a week or possibly more).  Heroin withdrawal can be extremely challenging for anyone to go through, as this is one of the most physiologically addictive substances known.  Why exactly is Heroin so addictive? explains this phenomenon in further detail:

Most addictive drugs change the way the brain’s motivation and reward systems work. The brain is designed to remember experiences that cause pleasure. It’s also designed to motivate us to repeat these experiences in the future. Addictive substances trick the brain, making it motivate us to seek drugs.

When it comes to Heroin withdrawal, the symptoms come on sooner than most expect.  How can you identify symptoms of Heroin withdrawal?  Here are a few things to look for:


Many of the other symptoms of Heroin withdrawal may include nausea and vomiting, agitation, insomnia, diarrhea, abdominal cramping, anxiety, muscle aches, and more.  These symptoms can last from a few days to a week. Some users will experience post-acute withdrawal, which may last for a few months.

If the user has abused Heroin for a lengthy period, this could drastically affect how long the individual will suffer withdrawal. provides in-depth detail as to what to expect during a Heroin Withdrawal Timeline.

Heroin Withdrawal Timeline (Provided by

Days 1-2Symptoms may begin as soon as 6 hours after the last dose. The pain will start to develop on the first day, typically muscle aches. These will intensify over the first 48 hours. Other symptoms during this period include anxiety, panic attacks, insomnia, shaking and diarrhea.
Days 3-5By the third or fourth day, withdrawal is in full swing. Symptoms during this time often include abdominal cramping, sweating, shivers and nausea/vomiting.
Days 6-7A week is typically the end of what’s known as acute withdrawal. During this time, the common muscle aches and nausea will taper off. Physically, former users will start to feel more normal though still worn down and tired.
Post-Acute Withdrawal Syndrome (PAWS)Symptoms of withdrawal may continue inconsistently for months after acute withdrawal. These are caused by neurological changes from heroin use. Common long-lasting symptoms include anxiety, depression, fatigue, insomnia, and irritability.

Signs of Heroin Addiction

After injecting Heroin, the effects work extremely fast, even within seconds.  As Heroin is one of the most physiologically addictive drugs available, the signs of addiction are easily identifiable.  According to Physical symptoms of heroin use include:

  • dry mouth
  • flushed skin
  • constricted pupils
  • falling asleep suddenly
  • slow breathing
  • loss of self-control
  • itching
  • nausea
  • vomiting
  • constipation
  • feelings of heaviness
  • confused thinking or disorientation
  • difficulty making decisions
  • memory loss

Will Heroin Show Up on a Drug Test?

Many have wondered if heroin is specifically detected on a standard drug test, or if a Heroin Drug Test actually exist.  The truth is: You won’t find Heroin labeled specifically on a standardized urine drug test.  However, Heroin is an opioid.  Opiates are one of the many drugs detected on a urine drug test.  For example, the 13 Panel Drug Testing Kit from 12 Panel Now detects up to 13 drugs. One of the categories of drugs detected is Opiates/Morphine.

These urine Drug Tests are designed to detect Opiate use among other drugs.  Heroin, Opium, Codeine, and Morphine (which is Heroins first metabolite) will all likely provide positive test reads under the Opiate/Morphine category.

Legally Prescribed Opiates May Be Detected

It’s important to note that a positive Opiate/Morphine read doesn’t necessarily mean that the donor has used an illegal opiate.  In fact, most urine drug tests that detect opioids won’t identify which specific drug was used.  This means that this may require more action on the part of the administrator to determine if the subject is using any legally prescribed opioids or other drugs that may cause a positive read.  If the donor tests positive for opiate use, the administrator would want to ascertain whether they are on any prescription medication that may cause a positive read.

Of course at the administrator’s discretion, a blood test or even a hair follicle test may be submitted to further identify drug use in the donor.  Some Hair follicle tests can identify drug use in subjects up to 30 days after the last use.
