Understand What is Methamphetamine

Meth, a short form of Methamphetamine, is classified as a Class II substance under the Controlled Substances Act by the US government since 1970. It is a psychoactive (mind-changing) stimulant that highly energizes one’s both mind and body.

It gives an immense and unmatchable sense of “rush” or “high” feeling after the first use that leads to consistently increased dosage while using every next time, just to get the same sensations. This ultimately gives rise to severe addiction to methamphetamine.

Before we further probe into its characteristics, here are some crucial statistics from National Survey on Drug Use and Health (NSDUH), 2021, depicting the alarming rise in meth addiction:

  • There was found to be approximately 6% of the US population, referring to over 16.8 million individuals of age as low as 12 who had utilized meth at least once in their life spans.
  • Also, the past annual data of meth users was averaged to be approximately 2.5 million individuals.

How Long Does Methamphetamine Stay in Your System? Have a Detailed Overview

On average, methamphetamine can stay in your system for at least 2-3 days. Certain factors determine how long does meth stay in your system. The prominent ones include:

  • Route of administration (drug intake)
  • Testing sample used for screening
  • Dosage and purity of meth
  • Frequency and duration of drug usage
  • Metabolism rate of the person under observation

Suppose you are needed to provide a negative meth drug test for any particular job, license, or sport; you must be wondering how long does methamphetamine stay in your system?

Well, meth might be detected in your system, and it primarily depends on the testing sample. Let’s probe into the most common testing samples used for meth drug testing as follows:

How Long Does Methamphetamine Stay in Your Blood System?

If you are opting for a blood test to detect methamphetamine in your system, then you might find it detectable for up to 25 hours after using it.

However, your drug test result may vary with certain factors, like gender, age, frequency and duration of drug usage, metabolism, and overall health history.  

How Long Does Methamphetamine Stay in Saliva?

In case of having an oral fluid or saliva test for meth detection, you might be able to give a positive drug test result for up to 48 hours. However, reducing the detection interval to 24 hours might give more accurate results

How Long Does Methamphetamine Stay in Hair?

As compared to other meth detection tests, the hair follicle test for detecting meth in your system gives quite a significant detection time span i.e. 90 days (3 months). However, after quitting the use of methamphetamine, you still need to avoid using it for at least six months

Hair test for meth detection is primarily applicable to research or forensic testing purposes rather than clinical testing. 

How Long Does Methamphetamine Stay in Nails?

The meth detection interval of nails is similar to that of hair as they both are made of a common protein called keratin.

As your nails grow, substances in the body might be incorporated into the nails. Therefore, even a 2-3mm sized nail sample can show meth detection in your system after 3 to 6 months of methamphetamine usage. 

How Long Does Meth Stay in Urine?

Depending on several factors, methamphetamine can be detectable in your urine sample for up to 3-5 days. If you are concerned about accuracy, you need to get yourself tested for meth detection for up to 3 days.

However, meth might be detected in your urine drug test even up to a whole week in case you are taking heavier doses of meth for a pretty longer duration.

How Does Your Body Deal with Meth? Meth Metabolism

Being a psychoactive stimulant, meth induces alterations in the way you think and behave. Methamphetamine can be used in various ways, including:

  • Oral intake
  • Smoking
  • Snorting
  • Injecting

The quick impact of meth spreads in the body more rapidly if injected or smoked rather than if used via insertion and oral intake. The drug enters the bloodstream, moving all over the body. However, the primary deposition of the drug takes place in: 

  • Brain
  • Liver
  • Lungs
  • Kidney

The brain induces a “pleasure effect” with consistent activity in brain cells. However, it might also cause death of brain cells, leading to loss of memory. Moreover, such after-effects may vary from person to person. 

Do you know?  It was estimated in a recent survey conducted in 2022 that 0.5% of grade-12 students, 0.3% of grade-10 students, and 0.2% of grade-8 students were reported to have used meth during the past 12 months. .

The major part of the remaining meth exits the body via urine. The rest of the meth is metabolized (broken down) into two components:

  1. Amphetamine (another addictive stimulant)
  2. Para-hydroxymethamphetamine (p-OHMA) (responsible for increasing blood pressure)

Eventually, these components are also meant to leave the body via urine. 

How to Interpret Your Meth Drug Tests?

Meth drug tests are used for detection of meth misuse in a person’s body via any of the common testing samples, including blood, saliva, nail, hair, or urine. After sampling, your results can either be negative or positive.

However, a negative meth drug test might imply any of the two possibilities:

  • Meth was not detected at all in the given sample.
  • Meth was detected in a pretty small quantity that was negligible enough to be marked negative.

Moreover, the two possibilities after a positive meth drug test include:

  • A considerable amount of meth was found in your given sample.
  • It might also be a false-positive test, leading to follow-up testing. 

Myth-Busters to Avoid Positive Drug Tests

Certain common myths make people believe they can make their meth drug tests result negative by following them. Unfortunately, they are not very reliable. Some of the most common ones include:

  • Drinking 24-36 ounces of water might make your meth drug test result negative since water would dilute the urine enough to make the quantity of meth negligible. However, it may not work, as the lab tests would indicate that urine is more diluted than its normal range.
  • Using diuretics (also known as water pills) also work on the same principle as urine dilution, but a higher amount of sodium in urine would confirm the use of diuretics to make your meth drug test result negative.
  • Lastly, some people try hair bleaching since bleach can break down meth present into different chemical components. Nonetheless, the presence of those chemicals in hair samples can prove the presence of meth in the first place.

Therefore, the valid way to get your meth drug test result negative is to completely quit having meth or any kind of drug abuse for good. 

A famous saying is:
There’s not a drug on earth that can make your life meaningful.
