In comparison to blood or hair, how long does heroin stay in your saliva? We’ll let you know so you can get back on track with your rehabilitation.


How Heroin’s Half-Life Affects Your System

The half-life of a drug indicates the amount of time it takes half of the dose to leave your body.

Heroin has a fast half-life of two to six minutes. That doesn’t mean that you’ll stop feeling the effects quickly, though.

As your body processes heroin, it transforms it into 6-acetyl morphine and morphine. Morphine has a half-life of up to seven hours.

It takes approximately five half-lives to eliminate a drug from the body completely.


If morphine had a half-life of six hours in your body, about 1/16 of the substance would remain after 24 hours.

Therefore, it’s clear that heroin, in some form, lingers in the system for a substantial number of hours.

However, the euphoric effect of heroin doesn’t last nearly as long.

Often, individuals will begin to feel the ‘high’ of heroin being to wane and look to use again.

This puts individuals at an extremely high risk of overdosing, as their body is still processing the opiates they had abused before.

How Long Does Heroin Stay In Your Saliva?

Your kidneys filter your blood, pulling out toxins, such as heroin, and eliminating them via your urine.

Other bodily substances, like sweat, tears, and saliva, can also remove heroin.

Clinicians often use saliva as a drug-testing method because it’s easier to obtain than urine or blood.

How long does heroin stay in your saliva? The answer may depend on the way that the person took the drug.

According to some researchers, peak concentrations of the drug exist in the saliva within two to five minutes after injecting heroin and two minutes after smoking it.

The concentration of heroin in the saliva diminishes quickly after intravenous administration.

Depending on the dose and frequency of use, injected heroin may not be detectable after just an hour. Inhaled heroin may show up in the saliva for up to 24 hours.

Yet, wondering if heroin can be detected in someone’s saliva is the wrong question to be asking.

Detection in an individual’s system depends on the type and quality of the test administered, the duration since the last time the individual used it, and the potency of the dose they last used.

Moreover, it is very difficult to hide drug abuse making the question moot.

How Destination For Teens Can Help With Drug Addiction

Heroin leaves the saliva so quickly that most drug screens evaluate its levels in the urine.

The substance is detectable in urine for up to two days for most users. Blood tests can detect heroin for up to six hours and morphine for up to 12 hours after use.

Drug screening may detect the drug in the system of people with an ongoing addiction longer than those who have only taken it once.

People with more fat in their bodies will also take longer to metabolize the substance.

Even though heroin may leave your body quickly, you might feel its physical and psychological effects for months or years.

The heroin addiction treatment program at Destinations for Teens offers holistic approaches that do more than help your teen manage withdrawal. They help them get their life back.

What Other Tests Can Detect Heroin in the Body?

Like a saliva test, heroin is only detectable in blood tests for five to six hours. Although, some people still have traces of the drug in their blood for up to two days.


Despite that, some new tests can distinguish heroin metabolites, which develop when the liver processes the drug. The metabolites stay in your system longer than the heroin toxins themselves.

A urine test, for instance, can detect heroin in your body for two days after you use it.

In some cases, though, the drug is measurable for up to a week.

With a hair follicle test, the presence of heroin is evident for three months or longer.

Because of that, hair follicle testing is the most-desired method of detection, but urine testing is the most cost-effective.

Factors That Affect Heroin Detection

Like your blood, urine, and hair, how long heroin stay in your saliva depends on several factors.

First, your weight and height have an effect on how much heroin you use to get high.

These measurements determine how long the drug stays in your system, too. In general, the bigger you are, the faster heroin leaves your body.

Second, how much heroin you use is a factor. As a rule of thumb, the more you take, the longer it will linger in your body.

Using high-quality heroin for a prolonged period can increase the duration of the drug in your system.

Your metabolism is a factor as well. If your metabolism is slow because you live a sedentary lifestyle, traces of the drug will linger.

Other factors that affect the detection of heroin include age, genetics, body fat, hydration, and liver and kidney health.

Is Heroin Metabolized?

Heroin is quickly deacetylated to give 6-monoacetylmorphine and morphine by successive deacetylation of two distinct ester linkages. Pseudocholinesterase catalyzes the hydrolysis of heroin to 6-monoacetylmorphine.

Will Poppy Seeds Show On A Drug Test?

Yes, it is possible. Eating poppy seeds before a drug test might give you a positive result, and you don't need to consume that many for it to happen. According to case studies and other research, even bagels, cakes, or muffins dusted with poppy seeds can result in a positive urine drug test.

Is Heroin Found In Urine?

After only two days, heroin is usually no longer identifiable in a person's urine. Certain tests, however, have been known to provide a positive result for this substance for up to 7 days. Because heroin, like many other opioids, has such a short half-life, blood and saliva tests are rarely utilized to detect it.
