Heroin: What Exactly Is It?

Heroin is an opioid drug derived from morphine, which comes from the seed pods of opium poppy plants in regions like Southeast/Southwest Asia, Mexico and Colombia. This addictive drug appears as a white or brown powder, or as a black sticky substance called black tar heroin.

Individuals use it in a variety of ways, including injection, sniffing, snorting, and smoking. Certain individuals practise speedballing, which is the mixing of heroin with crack cocaine. Short-term effects of heroin involve a rush of good emotions and clouded thinking.

It is not legally accessible by prescription in Australia, although it is offered on a limited basis to treat heroin addiction in Canada, the Netherlands, and the United Kingdom. Heroin use is associated with a significant risk of overdose and hazardous interactions with other substances and prescription medicines. Knowing how long an item may be active in your system may assist you in assessing risks and factors. Understanding the heroin effects, signs and  causes of heroin addiction is an important step toward healing and recovery.

Heroin is a Schedule 1 controlled substance, which means that it has no presently recognised medicinal purpose and significant potential for abuse. Due to heroin’s rapid onset and short half-life, it may sometimes be difficult to detect during routine drug tests. While the medication’s effects last about 30 minutes, the metabolites formed during its breakdown are detectable for approximately one to four days using conventional drug screening tests.

How Heroin Affects The Body

When heroin is ingested, it is transformed to morphine and quickly binds to opioid receptors. Individuals who take heroin often describe experiencing a wave of pleasant sensations referred to as a “rush.” The strength of the rush is dependent on the dosage and the rate at which the medication reaches the brain and attaches to opioid receptors. The rush associated with heroin is often accompanied by a warm flushing of the skin, a dry mouth, and a heaviness in the extremities. Additionally, nausea, vomiting, and extreme itching may occur. After the initial heroin effects wear off, users often experience many hours of drowsiness; brain function is impaired; heart activity slows; and respiration is also significantly reduced, sometimes to the point of being life-threatening. Additionally, slowed breathing may result in unconsciousness and irreversible brain damage.

Heroin Effects: How Long Does It Take?

Street heroin is illegally produced and contains a wide range of potencies, purity levels, and the combination of drugs it is sold with. Individuals who use heroin recreationally do it in a variety of ways, each of which has an impact on how quickly and how long the heroin effects last.

Heroin effects are immediate. A wave of strong euphoria lasts 45 seconds to a few minutes, depending on the dosage, while the remaining effects of heroin peak for one to two hours and most effects fade off after three to five hours, but sedation may last longer.

A rush of euphoria is often experienced, followed by a sleepy twilight state oscillating between alertness and sleep. Constricted pupils, nausea, flushed cheeks, and a dry mouth are among physical symptoms, as is the sensation of having heavy hands and feet.

How Long Does Heroin Stay in the Body

Heroin has a half-life of just two to six minutes and is rapidly converted to 6-acetyl morphine and morphine. Morphine has a half-life of between 1.5 and 7 hours, whereas 6-acetyl morphine has a half-life of just six to 25 minutes. A drug’s efficient elimination from the system takes between four and five half-lives.

Heroin and 6-acetyl morphine are more easily absorbed into the brain than morphine is. These drugs operate on receptors in the brain and nervous system that are implicated in pleasure, pain suppression, sedation, dysphoria, and, on a rare occasion, delusions and hallucinations.


Heroin can be detected in the urine for between one and four days following its last use by a standard urine test


The 6-AM assay test, initially designed for urine, has been proven to identify heroin metabolites in blood. These tests may be used to differentiate between recent heroin usage and therapeutic opiate consumption for pain treatment.


Saliva tests show significant amounts of the heroin metabolite 6-acetyl morphine. In certain cases, these tests may be more accurate than urine testing. However, to be successful, such tests must be performed soon after the previous usage.


Hair follicle tests can detect heroin for up to 90 days after use. However, people who have used heroin for a long time may have longer hair detection windows.

Factors Influencing Detection Time

As is the case with most narcotics, heroin is mostly excreted through the urine, although it can also be released through perspiration, tears, saliva, and faeces. The following factors affect the detection time of heroin:

Personal Factors

How long heroin is detectable in a conventional drug test is determined by many variables, including weight, body mass, and individual metabolism. Overall health, particularly liver and renal function, may also influence the rate at which heroin is metabolised and eliminated from the body.

Dosage and Frequency of Administration

The quantity of heroin consumed is the primary determinant in determining how long heroin remains detectable in a drug test and what will be the effects of heroin consumed. While heroin will only persist in the body for one or two days with moderate usage, it may be detected in a urine test for almost a week with severe, chronic use.

Purity of Drugs and Drug Interactions

Due to the fact that heroin is illegal, there is minimal uniformity in its purity. Certain dosages may be purer and stronger, lengthening the time required for the drug to be removed from the body. Additionally, interactions with other drugs may alter the rate at which heroin is metabolised.

Creating an All-Inclusive Heroin-Free Workplace Program

Establishing a well-thought-out drug and alcohol policy is always the greatest approach for a business to safeguard itself from workplace heroin problems. Through relevant programs, education of employees about heroin effects and other drugs, and workplace drug testing, a drug and alcohol policy provides clear and legal regulations to CEOs, human resources professionals, and safety officials regarding how to deal with heroin in the workplace.
