meth in your system

Methamphetamine, also known as meth, crystal, or ice, is a Schedule II substance in the US and considered highly addictive. It’s known more widely as a stimulant and work by flooding the brain with dopamine, norepinephrine, and serotonin, which results in a sense of euphoria. Meth is metabolized slowly, which means a longer high and larger impact on the central nervous system. But how long, exactly, is meth in your system?

Various drugs can inhibit users and cause a number of psychological, physical, and emotional issues, but not always with the same effects. Meth, in specific, is known to be negatively impactful on all of the above categories. Since it is rapidly absorbed, users typically reach meth’s peak effect in 2 to 3 hours. With continued use, meth reduces the levels of dopamine in the brain and requires an increase in drug use to obtain the same sensations. Learn more about meth in your system below.

What is the Half-Life of Meth?

If you’re trying to overcome an ice addiction, you may be wondering how long meth stays in your system. The reality is that the amount of time the drug remains present in the body is different for everyone. In order to understand how long it stays present, then, it helps to first understand what the half-life of methamphetamine is.

“Half-life” is a term used to describe the amount of time it takes for the body to metabolize a drug. It gets its name from the fact that all drugs take a certain amount of time to be metabolized by 50%. Some drugs take several days just for the body to flush out half of the quantity of the drug that the user consumed. The half-life of meth is around 12 hours. This means that it can take up to 12 hours for the user’s body to metabolize half of the total amount that they took.

How Long Can Meth Be Found in Your Urine?

You may be wondering how long meth stays in your system because you’re being drug tested for a job. If this is the case, it is likely that your employer will take a urine sample. Methamphetamine is detectable in urine for around 72 hours after the last dose. This means that if your last hit of meth was less than 3 days ago, it is likely that your urine will show traces of the drug.

If you are a habitual user, this time period will be longer. As meth accumulates in your body over time, it takes longer for it to leave your system entirely. Serious meth addicts can show traces of the drug in their urine for weeks after they stop using.

How Long Does Meth Stay in Your Blood?

Meth has a similar half-life in blood and urine. Therefore, it is likely that you’ll find traces of meth in your blood for around 3 days after you stop using. Again, when it comes to habitual meth users and people who take large quantities of the drug, this time period will be much longer.

The problem is that methamphetamine users often use the drug in heavy doses. As you continue to use the drug over time, its chemical byproducts gather in your liver. Once you stop using, it can take quite a few days for your body to expel it entirely.[vc_row anchor=”hair”]

Traces of Crystal Meth in Hair

The relationship between drugs and human hair is quite interesting. Our hair, after all, stores many traces of the chemicals that we take into our bodies. These traces can remain there for months, even years, after we stop consuming those chemicals.

When asking how long meth stays in your system, therefore, it’s tough to answer if we’re talking about hair. Some experts say that meth will remain in your hair for around 90 days. However, it has been shown that small traces can show up several years after your last use. They may not be present in every single hair, but it is possible that they’ll be around for quite some time.[vc_row anchor=”system”]

Factors that Influence How Long Meth is in Your System

There are quite a few factors that can affect how long meth stays in your system. Some of these factors include:

Quantity consumed: If you use large amounts of meth or consume the drug on a daily basis, you are likely to show evidence of methamphetamine use for a longer period of time. Folks who have only taken the drug once or twice will be able to flush it out much faster.

Liver health: The liver is the organ responsible for metabolizing drugs. If you have an unhealthy liver, therefore, you won’t be able to process methamphetamine as quickly as someone with a fully-functional liver.

Method of intake: Methamphetamine can be smoked, snorted or injected. Each of these methods has a different effect on the user. Additionally, these methods impact the drug’s half-life. Smoking any drug, for example, causes it to remain in the body for a longer period of time. An injection puts it directly into the bloodstream and therefore enables the body to break it down faster.[vc_row anchor=”getout”]

How to Get Meth Out of Your System
