Read on to discover everything you need to know about the lingering presence of meth in your body. 


The body metabolizes meth through different pathways, but it’s primarily metabolized in the liver. When it goes through the liver, it goes through chemical changes before it’s excreted from the body. One way is through renal excretion, and another way is through hepatic metabolism. 

How a person ingests the meth also impacts how fast the drug is metabolized and eliminated by the body. Some people smoke it, others inject it, or they consume it via oral ingestion, and each method makes a difference in how quickly it’s eliminated.

The presence of meth in the body depends on how frequently it’s used, the person’s metabolism, and other physiological factors. 

How Long Does Meth Stay In Your System?

If you are taking a drug test, whether it shows up in your system or not will depend on the type of test you take. If you take a urine test, then the drug can be detected for up to 1-4 days after use. Keep in mind that if the meth usage is heavy or chronic, the detection window in urine can be longer. 

When a blood test is done, meth can be detected in the bloodstream up to 1-3 days after use. If a saliva test is done, then it can be detected up to 1-2 days after use. If you’ve been dealing with this drug addiction, then detox for long-term recovery is a good idea if you don’t want any meth left in your system. 

Hair tests can detect meth use over a much longer period of time compared to other testing methods. It can be detected in hair follicles for several months to years after use, depending on the length of the hair sample that’s collected.

Factors Affecting Detection Time

Individuals who have a meth addiction may have higher levels of the drug in their system and may take longer to eliminate it compared to occasional users. Higher doses of meth can result in longer detection times, because more of the drug is metabolized and excreted from the body.

Individual differences in metabolism can impact how quickly meth is broken down and eliminated from the body. Factors like liver function, hydration levels, and overall health can influence the rate of metabolism.
