Meth is a strong stimulant, and addiction can develop whether it is smoked, snorted, injected or swallowed. This page explains how to recognize methamphetamine use disorder, what withdrawal tends to look like, and which treatments have research behind them. If you are concerned about your own use or about someone you love, help is available.
Key Points About Meth Addiction
- Signs of meth addiction can be physical, like weight loss and skin sores, behavioral, or psychological.
- Meth withdrawal is rarely life-threatening, but depression and suicidal thoughts can occur; call or text 988 anytime.
- Symptoms of meth withdrawal tend to peak in the first days and most ease within 2 to 4 weeks.
- No medication is FDA-approved for meth addiction; contingency management has the strongest evidence.
- Fentanyl is commonly mixed into meth, often without the person knowing; most deaths involving methamphetamine also involve opioids.

What Is Meth Addiction?
Meth addiction is the condition clinicians call methamphetamine use disorder: a person keeps taking the drug even as it damages their health, relationships or work, and stopping becomes very hard.
The Drug Enforcement Administration (DEA) calls meth a “Highly addictive” stimulant that, in its words, “speeds up body’s system.” It is sold as a powder or a pill, and the crystal form “resembles glass fragments”; on the street it goes by names like crystal, ice and crank. People smoke it, snort it, inject it or swallow it as a pill, the DEA notes, and smoking or injecting carries the most risk because the drug reaches the brain faster. According to the Substance Abuse and Mental Health Services Administration (SAMHSA), stimulants that are smoked or injected can drive brain changes that lead to stimulant use disorder.
In 2025, SAMHSA reports, 2.7 million people, those aged 12 or older, had used methamphetamine in the past year.
Quitting is hard for physical reasons, not weak will. Meth changes how the brain works, and SAMHSA’s treatment guidance notes that a person who uses meth may fall into a binge pattern that runs 3 to 15 days, which deepens the cycle of craving and use.
Signs and Symptoms of Meth Addiction
Signs of meth addiction usually show up in three places: the body, a person’s behavior, and their mood and thinking. The body shows weight loss, dental damage and skin sores; behavior shows long periods without sleep and new money or work problems; mood and thinking show paranoia, anxiety and hallucinations. Someone may have a methamphetamine use disorder if problems from meth continue and they cannot cut back.
Clinicians diagnose a stimulant use disorder with DSM-5 criteria: mild means 2 to 3 criteria, moderate 4 to 5, and severe 6 or more, per the American Society of Addiction Medicine. 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, according to the Substance Abuse and Mental Health Services Administration (SAMHSA).
Physical signs
- Severe tooth decay and tooth loss, often called “meth mouth” (National Institute on Drug Abuse, or NIDA)
- Skin sores from picking and scratching
- Weight loss
- Increased heart rate, blood pressure, breathing and body temperature, and dilated pupils (Drug Enforcement Administration, or DEA)
- For people who inject: cellulitis, skin abscesses, and infections from using or sharing unsterile needles, including HIV and hepatitis B and C (SAMHSA)
The Centers for Disease Control and Prevention adds that injecting drugs brings increased blood-borne infections: viral hepatitis, HIV, and bacterial and fungal infections.
Behavioral signs
A person on a meth binge may use for 3 to 15 days and then sleep for long periods after stopping, a crash, according to SAMHSA. Other behavioral signs include:
- Fatigue and sleepiness, sometimes mixed with insomnia
- Continuing to use meth even though it keeps causing problems
- Money, work or relationship trouble
- Taking higher doses or using more often
Psychological signs
- Anxiety and paranoia during use (DEA)
- Psychosis (paranoia, hallucinations), more likely at high doses; meth-related psychosis tends to last longer than cocaine-related psychosis (SAMHSA)
- Psychotic symptoms that can sometimes last for months or years after a person has quit meth (NIDA)
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.
Seeing several of the signs and symptoms of meth use in one person is a reason to take them seriously, not to wait for more.
Meth Withdrawal: Symptoms, Timeline and Safety
Meth withdrawal is not usually medically dangerous: StatPearls reports no mortality associated with stimulant withdrawal, but the Substance Abuse and Mental Health Services Administration (SAMHSA) cautions that the greatest risk during stimulant withdrawal is a person doing harm to themselves, and that suicidal ideation may be high during acute methamphetamine withdrawal. SAMHSA says symptoms often begin within hours to a few days after heavy use stops, then ease across 2 to 4 weeks, though cravings and a low mood can last 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.
The National Institute on Drug Abuse (NIDA) lists depression, anxiety, fatigue and an intense craving for the drug among the symptoms of meth withdrawal, and SAMHSA adds 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:
- Low mood or depression
- Anxiety
- Strong cravings for meth
- Exhaustion and long periods of sleep, sometimes mixed with insomnia
- Increased appetite
- Irritability, paranoia or agitation
- Headache, a pounding heart, sweating, and muscle or joint aches
The timing depends on how much a person used, how long they used, and differences from one person to another.
| Phase | Typical timing | What may happen |
|---|---|---|
| Crash (acute) | Begins within hours to a few days once heavy use stops; most intense during the first days (TIP 33) | Low mood, anxiety and strong cravings first, then exhaustion and a long sleep, sometimes with insomnia (TIP 33) |
| Withdrawal (post-acute) | Symptoms may continue across 2 to 4 weeks (TIP 33) | Hunger, fatigue, low mood, irritability, paranoia or agitation; headache, pounding heart, sweating, aches (TIP 33) |
| Protracted | Weeks into months (ASAM/AAAP 2024; TIP 33) | Low mood, loss of pleasure and cravings can linger; suicidal thoughts can occur (StatPearls 2024; TIP 33) |
The American Society of Addiction Medicine (ASAM) notes that post-acute symptoms of stimulant withdrawal can last for weeks to months and that suicidality may increase as intoxication wanes and acute withdrawal begins. StatPearls describes a protracted phase that can include depression with suicidal thoughts.
There is no medication that reverses meth withdrawal: StatPearls finds that 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, the Centers for Disease Control and Prevention (CDC) says.
- Hallucinations, severe paranoia or feeling unsafe around others: get urgent care. SAMHSA notes that some people who feel persecuted during methamphetamine withdrawal can become violent.
- Using alcohol, benzodiazepines or opioids at the same time: talk to a doctor or detox program before stopping those, because MedlinePlus warns that alcohol withdrawal “may quickly become life-threatening,” and the FDA cautions that 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
The National Institutes of Health (NIH) states that no medications have yet received FDA approval for methamphetamine use disorder, and 2021 guidance from the Substance Abuse and Mental Health Services Administration (SAMHSA) says the same for stimulant use disorders overall. The American Society of Addiction Medicine (ASAM) notes that doctors sometimes use existing pharmacotherapies off-label. A doctor may also treat co-occurring conditions such as depression, anxiety or sleep problems, and the Centers for Disease Control and Prevention (CDC) points out that no approved medication-based treatments exist 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. SAMHSA reports that ample research supports CM as the primary psychosocial treatment for these disorders, and ASAM’s 2024 guideline recommends, on high-certainty evidence, that CM should be a primary component of the treatment plan, because it outperformed every other intervention studied. The CDC calls CM the most effective treatment for stimulant use disorder and notes 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, De Crescenzo F et al. found that 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 the authors named it the most effective and acceptable intervention.
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 goal of the community reinforcement approach, in SAMHSA’s words, is “to identify behaviors reinforcing stimulant use and make a substance-free lifestyle more rewarding.” The National Institute on Drug Abuse (NIDA) describes the Matrix Model as “a 16-week comprehensive behavioral treatment approach” and finds that the most effective treatments for methamphetamine addiction at this point are behavioral therapies. 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). For a closer look at what recovery involves, read about meth addiction treatment.

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 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 the Substance Abuse and Mental Health Services Administration (SAMHSA) notes that using stimulants these ways can change the brain in ways that lead to stimulant use disorder.
- Injecting adds infection risks, from cellulitis and abscesses to HIV and hepatitis B and C when needles are shared, according to SAMHSA.
- Snorting or swallowing brings the drug on more slowly, but the same harms build with repeated use.
Short- and long-term effects
Short-term effects, several of them listed by the Drug Enforcement Administration (DEA), include:
- A burst of energy and long periods awake
- Little or no appetite
- A racing heart and higher blood pressure
- Faster breathing
- Higher body temperature
- Dilated pupils
The long-term effects of meth build over months or years of use. According to the National Institute on Drug Abuse (NIDA), common ones include:
- Severe tooth decay and tooth loss
- Skin sores from picking and scratching
- Significant weight loss
- Anxiety
- Paranoia
- Hallucinations and psychosis
The DEA warns that high doses can trigger convulsions, cardiovascular collapse or stroke, and can be fatal from heart attack, stroke or organ damage from overheating. SAMHSA identifies cardiovascular disease as the third most common cause of death for people who use methamphetamine, behind only overdose and accidents. Some of the harm is not permanent: NIDA reports that certain brain effects “appear to be at least partially reversible,” with some regions showing recovery after 14 months of abstinence but not at 6, and others not even at 14.
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: the CDC cautions that it is often mixed into other drugs, including methamphetamine, and that many people do not know their supply contains it.
A stimulant overdose looks different from an opioid one. The CDC lists its signs as 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.
Frequently Asked Questions About Meth Addiction
Meth withdrawal is rarely dangerous in a direct medical sense. StatPearls (2024) records no deaths caused by stimulant withdrawal on its own. The serious risk is what it can do to mood: deep depression and thoughts of suicide can come with it, according to StatPearls and the Substance Abuse and Mental Health Services Administration (SAMHSA), in its Treatment Improvement Protocol 33 (TIP 33). Anyone having thoughts like these can call or text 988, the 988 Suicide & Crisis Lifeline, at any hour. Using other drugs or alcohol alongside meth can change the picture, so a doctor should hear about everything that was being used.
The hardest stretch is usually the first few days. TIP 33 (updated 2021) says most symptoms may continue for 2 to 4 weeks. Some effects can linger far longer: a flat mood, disrupted sleep and cravings can persist for months, according to TIP 33 and the 2024 clinical practice guideline from the American Society of Addiction Medicine and the American Academy of Addiction Psychiatry (ASAM/AAAP).
No. There is currently no medication approved by the U.S. Food and Drug Administration (FDA) for methamphetamine or any other stimulant use disorder, according to SAMHSA’s TIP 33 and the National Institutes of Health (NIH, 2021). Research continues, and in one NIH trial more participants responded to a combination of naltrexone plus bupropion than to a placebo, 16.5% vs 3.4%. That is a research finding, not a recommendation, and a doctor is the right person to explain what it could mean.
Contingency management is a behavioral treatment that rewards drug-free test results with small incentives, often vouchers or prizes. Among the treatments studied for stimulant use disorders, it carries the strongest evidence, according to the ASAM/AAAP 2024 guideline and a 2025 report from the Centers for Disease Control and Prevention (CDC).
Yes. The CDC says fentanyl is commonly mixed with other drugs, methamphetamine among them, and that many people have no idea it is there. When someone may have taken opioids and is breathing poorly or cannot be woken, the CDC’s Stimulant Guide says to call 911 and give naloxone if it is available. Naloxone reverses opioid effects, which is what matters when fentanyl is in the mix.
