Methamphetamine

Methamphetamine is a powerful stimulant, usually sold as a white powder, pills, or crystal fragments that look like glass. It is chemically related to amphetamine, a medicine used for ADHD and narcolepsy.¹ It is smoked, snorted, swallowed, or injected.

Methamphetamine can produce intense energy, alertness, and confidence — followed by a crash. Over time, many people find they need it just to function, while it takes away sleep, appetite, health, and peace of mind.

Methamphetamine-related overdose deaths have risen sharply in the U.S. NIDA reports that about 32,537 people died in 2021 from overdoses involving psychostimulants other than cocaine, mainly methamphetamine.¹

DSM-5-TR includes methamphetamine under stimulant use disorder. ICD-11 classifies disorders due to use of stimulants, including amphetamines and methamphetamine.

Methamphetamine use disorder is diagnosed as a stimulant use disorder when use becomes hard to control and continues despite harm. The same criteria pattern applies as for other substances: loss of control, craving, neglect of responsibilities, and continued use despite consequences.

• Function, not only pleasure. Many people first used methamphetamine to stay awake through long shifts, to lose weight, to cope with exhaustion, or to feel confident.
• Binge-and-crash patterns. Runs of use over days followed by a crash of exhaustion and low mood can quickly reinforce more use.
• Co-occurring conditions. Depression, ADHD, trauma, and other substance use are common alongside stimulant use.²
• Environment. Availability, low price, social networks, and housing instability all play a role.

Methamphetamine causes a large release of dopamine and related signaling chemicals, and blocks their normal recycling. Those chemicals are involved in motivation, movement, attention, and learning which actions matter — not just in pleasure.

Repeated heavy use can change how these systems work, which may help explain the low mood, low motivation, and difficulty feeling pleasure many people experience after stopping. Research suggests some of these changes can partially recover with sustained abstinence, though recovery can take many months.

• The crash. Exhaustion, hunger, and low mood after use can make another dose feel like the only way to function.
• Early recovery is hard. In the weeks after stopping, many people feel flat, tired, and unmotivated. Knowing this is expected — and temporary for many — can help.
• Strong cue-triggered craving. Places, people, money, and even certain music can trigger intense urges.
• Sleep and appetite disruption. Unregulated sleep and eating make emotions harder to manage.

• Staying awake for long periods, then sleeping for very long periods
• Significant weight loss and decreased appetite
• Fast speech, restlessness, repetitive behaviors
• Dental problems, skin sores from picking
• Paranoia, suspicion, or seeing and hearing things others do not
• Irritability, aggression, or sudden mood swings
• Money problems, missing possessions, withdrawing from family

Heart and body

Raised heart rate and blood pressure, risk of heart attack and stroke, overheating, and severe dental and skin problems.

Psychosis

Paranoia, hallucinations, and delusions can occur, especially with heavy use and lack of sleep. They often fade with abstinence, but can persist or recur in some people.

Overdose

Methamphetamine alone can cause overdose. Many deaths now also involve fentanyl in the stimulant supply.³

Infections

Injecting and sexual risk-taking can increase the risk of HIV and hepatitis.

Life and family

Job loss, housing instability, legal problems, and children who need extra protection and support.

• There is no FDA-approved medication yet. That is frustrating — but effective treatment still exists, and behavioral approaches work for many people.⁴
• Paranoia can make help feel threatening. Approaching someone calmly, without confrontation, matters.
• Recovery can feel slow. The flatness of early recovery is one of the hardest parts. It tends to improve, and support helps people get through it.
• Stigma is intense. People who use methamphetamine are often portrayed through frightening images. People recover, and deserve to be treated as people.

• Prioritize sleep, food, and water — they are part of treatment, not extras.
• Remove supplies and contacts where you can, and change routines tied to use.
• Plan for the low-energy weeks: small, achievable goals help more than big ones.
• Look for a program that offers contingency management or the Matrix Model.
• If you keep using, reduce risk: carry naloxone, test for fentanyl, do not use alone, and avoid mixing substances.

NIDA describes behavioral therapies as the most effective treatments for methamphetamine addiction currently available, and notes that there are no medications yet that counteract its specific effects.⁴

Contingency management (CM)

Provides tangible rewards, such as vouchers, for verified drug-free tests and treatment participation. Studies show it increases periods of abstinence from methamphetamine.⁵

The Matrix Model

A structured 16-week program combining behavioral therapy, family education, individual counseling, 12-step support, drug testing, and encouragement of non-drug activities.⁴

Cognitive behavioral therapy

Helps people recognize and cope with triggers and craving.

Treatment for co-occurring conditions

Depression, psychosis, ADHD, and trauma deserve their own assessment and care.

Ask what a treatment program actually provides

Treatment names can be confusing. Contingency management is a structured behavioral approach that reinforces agreed treatment goals. A published randomized study found better substance-use outcomes when it was added to usual treatment, while retention in treatment was similar between groups. That supports asking about the approach; it does not establish that every program or every person will have the same result.⁵

You might ask: “Do you offer contingency management? What goals are reinforced? What other counseling and medical care are included? How often would I attend, and what happens if I miss an appointment?” If it is unavailable, ask what other care can start now and whether there is a referral or waiting list. Bring the answers to a qualified clinician rather than comparing programs only by their advertising.

A practical appointment note can include your sleep pattern, mood, appetite, physical symptoms, other substances or medicines, and what makes attendance difficult. You do not need to present a perfect recovery plan to deserve care. Pick one concrete follow-up action you can understand and carry out, such as confirming an appointment time or asking a trusted person for transport. These are planning suggestions, not a clinical protocol.

1. Call 911 for chest pain, overheating, seizures, or extreme agitation or confusion.
2. Sleep, eat, and drink water. A crash is not dangerous by itself, but it can bring deep low mood.
3. If you are having thoughts of suicide, call or text 988.
4. Carry naloxone and avoid using alone — the supply may contain fentanyl.
5. Call the SAMHSA National Helpline (1-800-662-4357) to find programs offering contingency management.

• Approach calmly and avoid arguing about what is real if they seem paranoid. Focus on safety, sleep, and food.
• If someone is a danger to themselves or others, or very confused or overheated, call 911.
• Recognize that early recovery may look like exhaustion and low mood; encouragement and patience help.
• Protect your own safety and finances, and get support for yourself.
