Methamphetamine (meth) is a dangerous, illicit stimulant drug. Using meth can lead to serious short and long-term complications, including physical dependence. People who use meth are also at risk of a life-threatening overdose.
Overcoming meth dependence can be challenging. People who stop using methamphetamine may experience intense withdrawal symptoms that last for weeks. Prolonged withdrawal symptoms can increase the risk of a relapse.
This article will explore how long meth stays in the body after you stop using it. You will learn:
- The risks and effects of meth use
- How the body detoxes from meth
- How long meth withdrawal may last
- The detection windows for different drug screening tests
- Where to find comprehensive treatment and recovery support programs

What is Meth?
Methamphetamine (meth) is a potent, synthetic stimulant drug. This drug increases central nervous system (CNS) activity. People make meth using household chemicals and medications. It is typically a white, odorless powder or a solid crystal form.
Methamphetamine use can cause short and long-term side effects. The short-term effects of meth include:
- Elevated blood pressure
- Faster heart rate and breathing
- Increased body temperature
- Insomnia
- Anxiety
- Aggression
- Violent behaviors
- Tremors
- Paranoia
People are also at risk of stroke, heart attack, and seizures when using meth.
Using meth for a prolonged period can have severe effects on a person’s mental and physical health. Some of the long-term effects of meth use include:
- Changes or damage to the brain
- Confusion
- Hallucinations
- Increased risk of cardiovascular issues
- Depressions
- Aggression
- Increased risk of bloodborne diseases like HIV and hepatitis C
- Physical symptoms, such as severe dental decay, scarring and skin issues, and extreme weight loss
People who use meth may develop physical dependence on the drug. Once someone develops a dependence on meth, it can be very challenging for people to stop using it when they choose. Most people require intensive treatment to stop and ongoing support to prevent relapse.
How Long Does Meth Stay in Your System?
The liver begins to metabolize meth as soon as it reaches the bloodstream. Meth’s half-life (the time it takes for the body to eliminate half of a substance) is about 10 to 12 hours. However, the effects of meth can last much longer than this, depending on the form of meth you use. In some cases, the effects of meth can last for 24 hours or longer.
There are many factors that affect how long meth stays in the body. These include:
- The dose you use
- How often you use meth
- Weight and body composition
- Age
- Gender
- Kidney and liver health
- General health
- Co-occurring mental health conditions
- Other substances you used at the same time

Understanding Meth Withdrawal
Meth withdrawal can be very challenging. Many people experience intense, uncomfortable withdrawal symptoms that last for days or weeks.
Withdrawal symptoms typically start within about 24 hours of a person’s last dose of meth. Acute withdrawal symptoms include:
- Intense cravings
- Chills
- Depression
- Anxiety
Over the next week, withdrawal symptoms are likely to intensify. People may experience:
- Fatigue
- Mood swings and irritability
- Sleep problems (insomnia followed by too much sleep)
- Increased appetite and weight gain
- Difficulty with concentration and focus
- Intensifying depression with the potential for suicidal thoughts
- Difficulty feeling pleasure
Withdrawal symptoms may last for several weeks or longer. During this time, strong and persistent cravings are common. People must have treatment and support to safely navigate meth withdrawal without relapsing.
How Long Can Drug Tests Detect Meth?
Drug tests may be able to detect meth for longer than the drug’s effects last. Here is an overview of the detection window of several types of drug screenings.
Urine tests
Urine testing is the most common form of drug screening because it is non-invasive and inexpensive. This form of testing produces quick, accurate test results and is common in employment and medical settings. Many factors can affect how long meth stays in urine. Generally, this type of testing may detect meth in urine for up to 72 hours after your last dose.
Saliva tests
Saliva testing may detect meth for up to four days after your last dose.
Blood tests
Blood testing has a detection window that is similar to saliva testing. Blood testing may detect meth for up to four days after your last dose.
Hair tests
Hair testing is uncommon but has a long detection window. Hair testing may detect meth for up to 90 days after your last use.
If you are concerned about drug testing results, you may need support to overcome meth use or dependence. Contact the mental health and medical professionals at Blue Star Recovery to explore your treatment options or to schedule an intake appointment.
