Meth Addiction

Methamphetamine use disorder is a pattern of drug use that you can’t easily stop. The craving to keep using is a physical urge. Here you’ll discover how to recognize this disorder, what withdrawal involves, and which treatments are effective. You’ll also learn how fentanyl in the drug supply has ramped up the risk of meth overdose.

What Is Meth Addiction?

Meth addiction is the condition that clinicians refer to as methamphetamine use disorder. A person is experiencing this disorder if they keep taking meth even though it’s damaging their health, relationships or work.

Meth is a highly addictive stimulant that speeds up your body’s systems. It’s sold as a powder or a pill, and the crystal form (the one people often picture when they hear crystal meth addiction), resembles glass fragments. Its street names include crystal, ice and crank.

People smoke it, snort it, inject it or swallow it as a pill. Smoking and injecting are the riskiest methods because the drug reaches the brain faster. Stimulants that are smoked or injected can cause changes in the brain that lead to stimulant use disorder.

SAMHSA has reported that in 2025, 2.7 million people aged 12 or older used methamphetamine in the past year. The organization estimates that 1.8 million people 12 and older have a methamphetamine use disorder.

Quitting is hard for physical reasons. Meth changes how the brain works, and a person who uses this drug may fall into a binge pattern that lasts three to 15 days. This binging deepens and perpetuates the cycles of craving and use.

Signs and Symptoms of Meth Addiction

You can usually find signs of meth use in three places: body, behavior, and brain. Physically, meth damages the body and causes weight loss. It also changes behavior, causing difficulties with work, finances and relationships. And its effects on the brain cause changes in thinking and mood, often resulting in anxiety, paranoia or even hallucinations. 

If problems caused by meth use continue but the person can’t cut back, they may have a methamphetamine use disorder. Clinicians diagnose a stimulant use disorder with DSM-5 criteria and grade it as mild, moderate or severe.

According to SAMHSA, among people with a central nervous system stimulant use disorder in 2025, about half (47.9%) had a severe disorder and 29.8% had a mild disorder.

Worried About Someone Who Uses Meth?

Choose a quiet moment when they are not high and not crashing. Tell them what you have seen, and that you care. Many of these signs can come from other causes, so the aim is a conversation and a visit with a doctor, not proof. Learning how to help a loved one with addiction can make that first talk easier, and some families find support in family therapy. When they mention suicide or seem to be in danger, reach the 988 Suicide & Crisis Lifeline by calling or texting 988, or by chatting online; conversations are free, confidential and available around the clock, and the Lifeline supports people with alcohol or drug use concerns. For an emergency, call 911.

Meth Withdrawal: Symptoms, Timeline and Safety

The greatest risk during stimulant withdrawal is of doing harm to self. Suicidal ideation may be high during acute methamphetamine withdrawal. Withdrawal can begin a short time after someone stops heavy use, and can last several weeks. Low mood and cravings sometimes persist longer. If you or someone you know is thinking about suicide, call or text the 988 Suicide & Crisis Lifeline at 988; it is free, confidential and available around the clock.

If you or someone you love is thinking about suicide, call or text 988 now. Call 911 for chest pain, a seizure, or very high body temperature, and if the person is not responding.

Depression, anxiety, fatigue and an intense craving for the drug are among the symptoms of meth withdrawal, and also exhaustion and long sleep sometimes mixed with insomnia, increased appetite, paranoia and agitation, and physical symptoms such as headache, a pounding heart, sweating and muscle or joint aches. Common symptoms include:

The timing depends on how much a person used, how long they used, and differences from one person to another.

Post-acute symptoms of stimulant withdrawal can last for weeks to months, and suicidality may increase as intoxication wanes and acute withdrawal begins. A protracted phase can include depression with suicidal thoughts.

There is no medication that reverses meth withdrawal: no specific medications can abate symptoms, so care is supportive, meaning rest, food, fluids and monitoring of mood, with a clinician treating specific symptoms as they arise. A medical detox program can provide that monitoring during the first days.

When to get medical help:

• For thoughts of suicide or of self-harm, call or text 988.
• Chest pain, seizure, very high body temperature, confusion or not responding: call 911. Overheating, confusion, tremor, hallucinations and psychosis are signs of stimulant overdose.
• Hallucinations, severe paranoia or feeling unsafe around others: get urgent care. Some people who feel persecuted during methamphetamine withdrawal can become violent.
• Using alcohol, benzodiazepines or opioids at the same time: for people who drink heavily or take a benzodiazepine regularly, stopping suddenly is dangerous, so talk to a doctor or detox program first, because alcohol withdrawal may quickly become life-threatening, and stopping a benzodiazepine suddenly can cause seizures, which can be life-threatening.

Treatment for Meth Addiction

Behavioral therapies are the backbone of treatment for meth addiction, and the strongest evidence sits behind contingency management, an approach that rewards drug-free test results. No medication has FDA approval for methamphetamine or any other stimulant use disorder yet, though research is ongoing.

Medications

Doctors sometimes use existing pharmacotherapies off-label. A doctor may also treat co-occurring conditions such as depression, anxiety or sleep problems.

One trial, ADAPT-2 (2021), found that bupropion plus naltrexone produced a response in 13.6% of participants, against 2.5% on placebo. Neither is approved for stimulant use disorder.

Contingency management

Contingency management, or CM, works simply: a person earns small rewards, usually vouchers or prizes, when a drug test comes back negative. Ample research supports CM as the primary psychosocial treatment for these disorders, and CM should be a primary component of the treatment plan, because it outperformed every other intervention studied. CM is the most effective treatment for stimulant use disorder and it is underused. CM also does its best work inside a full plan: in a 2018 network meta-analysis of 50 randomized trials with 6,942 participants, CM combined with the community reinforcement approach was the only intervention that increased the number of abstinent patients at the end of treatment compared with usual care, and it was the most effective and acceptable intervention.

Five state Medicaid programs are approved to cover CM, KFF reported in 2026.

Other therapies with evidence

A full plan usually pairs contingency management and other therapies, and several talk therapies carry strong support. SAMHSA’s 2020 evidence guide rates motivational interviewing, the community reinforcement approach and cognitive behavioral therapy, alongside CM, as “Strong Evidence” for stimulant use disorders. The community reinforcement approach sets out to identify the behaviors that reinforce stimulant use and to make a substance-free life more rewarding. The Matrix Model is a structured behavioral treatment program that runs 16 weeks, and behavioral therapies are the treatments with the most evidence for methamphetamine addiction so far. Programs may also involve loved ones through family therapy, and mutual support groups can bring peer support in alongside treatment.

These therapies are delivered across levels of care, from outpatient to residential, and a clinician or an assessment helps decide which fits.

Taking the first step can feel like the hardest part, and knowing how to ask for help makes it easier: a first call usually starts with questions about what a program offers and how intake works. The CDC also points people seeking treatment information to SAMHSA’s National Helpline at 1-800-662-HELP (4357).

Risks and Effects of Meth Use

Meth speeds the body’s systems up, raising heart rate along with blood pressure and body temperature, and heavy use can lead to stroke, psychosis (a break from reality that can bring hallucinations and delusions) and lasting damage to teeth and skin. Today the deadliest risk is fentanyl in the drug supply: most overdose deaths involving methamphetamine also involve opioids.

Effects by how meth is used

How a person takes meth changes both its speed and its risks:

• Smoking or injecting brings on the fastest effects, and using stimulants these ways can change the brain in ways that lead to stimulant use disorder, a pattern of use that causes harm and is hard to stop.
• Injecting adds infection risks, from cellulitis, a spreading skin infection, and abscesses to HIV and hepatitis B and C when needles are shared.
• Snorting or swallowing brings the drug on more slowly, but the same harms build with repeated use.

Overdose and fentanyl

The Centers for Disease Control and Prevention (CDC) counted 28,722 overdose deaths involving psychostimulants with abuse potential, mostly methamphetamine, in 2024, and the rate dropped 19.8% from 2023, from 10.6 to 8.5 per 100,000. The CDC also reported a third straight yearly drop in overall overdose deaths in 2025 (about 69,973, provisional), with deaths involving psychostimulants and cocaine decreasing as well; no meth-specific 2025 figure exists.

A 2025 CDC analysis found that between January 2021 and June 2024, 31.2% of overdose deaths involved methamphetamine, and that 68.8% of deaths involving methamphetamine also involved opioids.

Fentanyl drives much of that overlap: it is often mixed into other drugs, including methamphetamine, and many people do not know their supply contains it.

A stimulant overdose looks different from an opioid one. Its signs are dangerous overheating, with the person often conscious and breathing quickly, along with dilated pupils, tremor, confusion, nausea or vomiting, hallucinations and psychosis. If someone shows these signs, call 911. Give naloxone whenever opioids might be involved: it reverses an opioid overdose even though it does not treat a stimulant overdose. In 2024 the American Society of Addiction Medicine (ASAM) recommended that clinicians prescribe or supply naloxone to patients who use stimulants nonmedically.

Short- and long-term effects

Short-term effects include:

The long-term effects of meth build over months or years of use. Common ones include:

• Severe tooth decay and tooth loss
• Skin sores from picking and scratching
• Significant weight loss
• Anxiety
• Paranoia
• Hallucinations and psychosis

High doses can trigger convulsions, cardiovascular collapse or stroke, and can be fatal from heart attack, stroke or organ damage from overheating. Cardiovascular disease is the third most common cause of death for people who use methamphetamine, behind only overdose and accidents. Some of the harm is not permanent: certain brain effects appear to be at least partly reversible, with some regions recovering after 14 months of abstinence and not at 6, and others not even then.
