One might pose this question for several reasons. Consider the following to determine if you potentially fall into any one of these categories:

  • You’re curious about chronic meth users and how long meth shows up on a urine test or hair test.
  • You’re wondering how long meth stays in your system because you’re curious about the half-life and the potential withdrawal symptoms that come with abstinence.
  • You have concerns regarding meth use and the potential physical symptoms or mental health problems it causes.

How Does Meth Interact With the Body?

When someone is actively engaging in drug addiction with meth as their drug of choice, this drug uniquely interacts with the body when compared to other substances. After you consume meth, you quickly experience the direct impact – especially if drug purity is particularly high.

The drug works its way to the brain where it causes a swift release of dopamine. This is the neurotransmitter in the brain that causes feelings of pleasure and reward.

When you’re praised for doing a good job – or feel proud of accomplishing something – the body releases dopamine. However, in the case of meth use disorder – the rush of this highly addictive drug is so intense that the feelings of pleasure turn into a chase. The user continues to abuse meth regularly in an attempt to duplicate these same feelings.

Repeated Drug Use: The Dangers of a Meth High

Subsequent use of methamphetamine leads to substantial damage to the heart, brain, and other organs in the body. The short-term impact, which can also be referred to as the high the user experiences, includes heightened levels of awareness, decreases in appetite, and enhanced physical activity.

Users often focus on one action and repeat it over and over – this is an action otherwise known as “tweaking.” The user becomes obsessed with repeating an action, often spending hours on end duplicating this same pattern of behavior.

How long does meth keep the user high? Compared to other substances, the high experience from meth is substantially longer. However, to the user, these short-term effects don’t last long enough, usually leading to an intense crash from meth that severely impacts the mood and levels of irritability.

After a user experiences the crash, they become depressed and deal with high levels of fatigue, often feeling too drained to even accomplish the simplest of activities.

Long-Term Effects of Crystal Meth

Long-Term Effects of Crystal Meth

Over an extended period, meth significantly impacts the normal function of the brain. Long-term users may develop symptoms such as memory loss, attention deficit disorder, challenges completing simple tasks, and in the worst cases – severe bouts of meth psychosis.

One of the most severe effects of meth abuse is paranoia. Many users report full-blown hallucinations of the auditory and visual variety – leading to dangerous episodes that can potentially cause injury or death.

The collateral damage of meth abuse includes the contraction of dangerous diseases – especially if the user prefers to abuse the drug intravenously. There is a significant risk of the user contracting Hepatitis C and HIV, especially after sharing needles with other users. In addition, meth abuse leads to sexual promiscuity in many cases, also heightening the risk for sexually transmitted diseases.

Understanding these elements, the question of, “How long does meth stay in your system?” becomes simpler to answer – depending on the origin of the inquirer. In the next section, we elaborate on this further.

How Long Does Meth Stay In Your System: Detecting Meth In Various Ways

How long does crystal meth stay detectable in a drug test? How long does meth stay detectable in the blood? How long is the half-life of meth? All of these questions sound similar, but the answer to each one is completely different.

If someone is using a hair follicle test to detect methamphetamine, the length of time is much longer than someone using a urine test. In addition, testing the blood after drug use generally has the smallest window of detection.

Three significant factors impact the length of time meth stays in your system. In the section below, we examine each of these factors in detail.

Amount and Length of Use

Meth Use

The specific amount of meth a user ingests weighs heavily on the length of time it remains detectable in the human bodyLargerer doses used for extended periods lead to a larger buildup of the drug in the system, leading to longer times of expulsion and detoxification.

The half-life of meth becomes very important when answering this question. A substance’s half-life – or the amount of time it takes for the body to expel exactly half of the amount a user ingests, helps determine the exact length of time it takes for the body to detox. On average, it takes the body around 10 hours to eliminate half of the amount present in the bloodstream.

It’s important to note that this doesn’t expel the entire amount from the body. It generally takes several half-lives for the body to completely break down and fully eliminate meth from the body.

After calculating the appropriate amount of half-lives, it takes about 72 hours for the body to fully expel a complete dose of methamphetamine from the body.


The body’s metabolism also plays a huge role in the length of time the body detoxifies from meth use. Every person has a different rate of metabolism. As a whole, your BMI (Body Mass Index), total body weight, and your age determine the speed of your metabolism.

Skinnier people who weigh less tend to have much faster rates of metabolism. Someone who is substantially larger with more body fat will have a much lower metabolism. For these individuals, meth can take much longer for the body to rid itself of all traces of the drug.

Meth and the Metabolic Process

Your metabolism is the process that breaks down any substances introduced into various body systems. Because meth passes through your liver, it must undergo the metabolic process for the body to eliminate it. The healthier you are overall, the faster your body expels substances during detox from meth and other drugs.

Several factors influence the metabolism aside from the ones listed above – including water intake, vegetable consumption, and other elements. Consumption of sugar can also significantly impact your metabolic rate.

Purity of the Drug and Method of Ingestion

The purity of the methamphetamine consumed, in addition to various factors regarding additional cutting agents – will also impact the length of time it takes to produce a negative test. The method of methamphetamine use also factors heavily into detection in blood tests and hair follicles.

If a user smokes or eats meth, it usually takes longer for the body to eliminate it. However, users who abuse meth intravenously will experience a much faster expulsion period. This is because the body breaks the drug down faster after IV use. After all, it bypasses the liver. There’s no need for this organ to metabolize the drug, which also plays a role in the intensity.

When the drug goes directly to the blood and brain, it heavily impacts the central nervous system, blood pressure, and overall health.
