Opioid use disorder has three approved medicines. Alcohol has three. Methamphetamine has none. Everything that might work is currently inside a study.
That single fact shapes everything about meth withdrawal and recovery, and it is rarely stated plainly. There is no equivalent of buprenorphine or naltrexone here. No pill your doctor can write. The entire pharmacological toolkit for methamphetamine use disorder exists only as research.
Knowing that changes how you read the timeline below, because the hardest stretch is precisely the one nobody can currently medicate.

The timeline
Day 1 to 3, the crash: Overwhelming exhaustion and sleep, sometimes for very long stretches. Big appetite. Low mood. Physically this phase is mostly survivable rest.
Day 4 to 10: Sleep becomes disturbed rather than endless. Depression, anxiety, agitation and strong cravings appear. Concentration is poor.
Week 2 to 4: The flat phase. Little pleasure in anything, low motivation, cravings triggered by cues. This is where most returns to use happen.
Month 2 to 3 and beyond: Mood, sleep and the ability to enjoy ordinary things gradually return. Recovery here is measured in months, not days.
The medical term for that flat phase is anhedonia, the loss of the ability to feel pleasure. Methamphetamine floods the brain's dopamine system far beyond anything ordinary life produces, and the system takes time to recalibrate. Nothing feels good for a while, including things that used to. It is temporary, and it is also the single biggest reason people go back.
The trial that changed the field
A useful fact. In 2021 the ADAPT-2 trial, published in the New England Journal of Medicine, tested injectable naltrexone combined with oral bupropion in 403 adults with moderate or severe methamphetamine use disorder. Response, defined as at least three of four negative urine tests at the end of a treatment stage, was 13.6% with the combination against 2.5% with placebo. That gap of 11 percentage points was the first clearly positive result of its kind in this field.
Those numbers deserve honesty in both directions. Thirteen percent is not a cure, and most participants did not respond. But it was five times the placebo rate in a condition where every previous medication trial had come up empty, and it opened a direction researchers are still following.
What does work right now
The strongest evidence for methamphetamine use disorder is not a drug at all. It is contingency management, a structured behavioural approach in which people receive escalating rewards for verified periods without use. It has decades of evidence behind it, and as of September 2026 there are 116 recruiting studies using it as part of their design.
Alongside that, standard elements help more than they get credit for: regular sleep, eating properly during the crash, treating co-occurring depression or anxiety rather than assuming everything is withdrawal, and having someone to call in week three.
What is recruiting
As of September 2026 there are 32 studies recruiting for methamphetamine and 23 for stimulant use disorder in the US. They include combinations building on the ADAPT-2 result, repurposed medicines from other conditions, contingency management delivered through apps and phones, and studies of treatments aimed specifically at the anhedonia phase.
Most enrol adults who are currently using. You do not need to be abstinent first, and in many designs being in active use is the point, because the study is measuring whether the treatment helps you stop.

Common questions
How long does meth withdrawal last? The crash lasts one to three days and acute symptoms mostly settle within two weeks. The flat, low motivation phase commonly lasts several weeks and can extend to a few months.
Is meth withdrawal dangerous? It is rarely life threatening in the way alcohol or benzodiazepine withdrawal can be. The serious risk is psychological: severe depression, and in some cases suicidal thoughts, during the weeks after stopping. That is a reason to withdraw with support rather than alone.
Is there a medication for meth addiction? None is FDA approved. Combinations such as naltrexone with bupropion have shown benefit in research, and several approaches are in active trials, but there is no equivalent of the approved medicines for opioids or alcohol.
What is contingency management? A treatment in which people earn escalating rewards for verified periods without use. It has the strongest evidence of anything currently available for stimulant use disorder and is part of many studies now recruiting.
Can I join a study if I am still using? Usually yes, and often that is required. Many stimulant studies enrol people who are currently using because the outcome being measured is whether use goes down.
Why is the second week harder than the first? The first days are mostly exhaustion and sleep. By the second week the dopamine system is still recovering, so ordinary things feel flat while cravings are strong. That combination is what makes weeks two to four the highest risk period.
