Key Takeaway
Consider exercise and TMS for craving reduction in methamphetamine use disorder based on network meta-analysis evidence.

This network meta-analysis synthesized evidence regarding interventions for methamphetamine use disorder, specifically focusing on craving reduction and quality of life. The analysis included exercise, transcranial magnetic stimulation (TMS), transcranial direct current stimulation, behavioral therapy, and acupuncture, comparing them against conventional rehabilitation across a sample of 3174 individuals.

Key findings indicate that exercise and TMS demonstrated statistically significant benefits for craving reduction compared to conventional rehabilitation. Furthermore, combined aerobic/resistance exercise and 10 Hz repetitive TMS targeting the left dorsolateral prefrontal cortex emerged as the most effective specific protocols within their respective categories for this primary outcome.

Regarding secondary outcomes, preliminary evidence from a limited number of studies indicated that exercise, acupuncture, and behavioral therapy improved patients' quality of life. The authors highlight that this evidence for quality of life comes from a limited number of studies, which serves as a primary limitation for drawing firm conclusions on this specific metric.

The study aims to provide a robust evidence base to inform clinical decision-making and guide the future development of methamphetamine use disorder treatment guidelines. Safety data, including adverse events and tolerability, were not reported in the included studies.

Non-drug options show real promise

New evidence suggests physical activity and brain tech are stepping in. Experts reviewed 53 studies to find the best ways to help.

They looked at over 3,000 people in total. The goal was to see what worked best for cravings.

The results were clear. Exercise and brain stimulation worked better than conventional rehabilitation.

How exercise changes brain signals

Think of the brain like a traffic system. Methamphetamine creates a jam in the roads.

Exercise helps clear the road. It sends fresh blood and oxygen to the brain.

This flow helps reset the signals that drive the urge to use.

Specific types of movement worked best. Aerobic exercise combined with resistance training was top tier.

Why the brain responds to movement

Another method uses magnetic pulses on the head. This is called transcranial magnetic stimulation.

It targets a specific part of the brain that controls decisions. The left side of the brain is key here.

This doesn't mean this treatment is available yet.

The study found this method reduced cravings significantly. It worked alongside the physical exercise results.

Quality of life also improved with other methods. Acupuncture and behavioral therapy helped patients feel better overall.

What happens when treatment works

The findings create a new framework for doctors. They can now match the right tool to the patient.

This helps guide future treatment guidelines. It moves care away from just pills.

However, the study had some limits. Some of the individual studies were small.

More work is needed to confirm these results. We need larger groups of people to test this.

The road ahead for patients

Doctors will have more tools soon. Guidelines are being updated based on this evidence.

Patients should talk to their providers about these options. They may not be ready for every clinic.

Research takes time to reach everyone. But the path forward is becoming clearer.

Hope is growing for those fighting this disorder. Better support means a better chance at recovery.

OBJECTIVES: We evaluated the effects of non-pharmacotherapy on quality of life (QOL) and craving in individuals with methamphetamine use disorder (MUD), ranking the efficacy of various protocols. METHODS: We searched multiple databases for randomized controlled trials from inception to Dec 2025. The analysis included 53 studies with 3174 participants, investigating interventions such as exercise, transcranial magnetic stimulation (TMS), transcranial direct current stimulation, behavioral therapy, and acupuncture. The protocol was prospectively registered in PROSPERO (CRD42023443291). RESULTS: For craving reduction, both exercise and TMS demonstrated statistically significant benefits compared to conventional rehabilitation. Combined aerobic/resistance exercise and 10 Hz repetitive TMS targeting the left dorsolateral prefrontal cortex emerged as the most effective specific protocols within their respective categories. Furthermore, preliminary evidence from a limited number of studies indicated that exercise, acupuncture, and behavioral therapy improved patients' QOL. CONCLUSION: This study confirms that several non-pharmacotherapies are effective for managing craving in MUD. Exercise and TMS are particularly promising for reducing craving. The findings, synthesized within a novel "Intervention-Circuit-Symptom" integrative framework, provide a robust evidence base to inform clinical decision-making and guide the future development of MUD treatment guidelines.
