Drug rehab in Thailand

The short answer

Good drug rehab starts with a medical assessment and safe withdrawal, then combines therapy, medicines where they help, and a plan for life back home. Centers in Thailand that publish prices charge a median of US$11,834 for 28 days, often with detox, medicines and hospital care extra.

Thailand's drug laws are strict, so bring no drugs with you and check every prescribed medicine against Thai FDA rules.

What does drug rehab involve?

NIDA says most people need at least 3 months in treatment to significantly reduce or stop their drug use.^[1]

The US National Institute on Drug Abuse (NIDA) sets out principles that apply in any country. No single treatment suits everyone, and a plan should be reviewed and changed as needs change. Medicines are an important part of treatment for many people, especially combined with counselling.^[1]

NIDA also notes that many people with addiction have other mental health conditions, and that detox alone does little to change long-term drug use.^[1] A residential program is one way to get this care; in the UK, the NHS says most people are treated while living at home.^[2]

A typical residential program in Thailand combines a medical assessment and, if needed, detox, then one-to-one and group therapy, a daily routine, family sessions and relapse-prevention planning. Our guide to what happens in a 28-day rehab walks through a typical month.

How does treatment differ by drug?

The core of treatment is similar for every drug, but withdrawal risks and the role of medicines differ a lot. That is why a doctor's assessment should come before you choose a program.

Opioids. The World Health Organization found that maintenance medicine combined with psychosocial support was the most effective of the options it reviewed for opioid dependence.^[3] In April 2026 WHO reaffirmed its strong recommendation for methadone and buprenorphine maintenance.^[4] If a center expects everyone to stop all opioids, ask how it protects people from overdose after they leave.

Stimulants. NIDA says there are no medicines approved by the US FDA to treat methamphetamine or other stimulant use disorders. Behavioural treatments, especially contingency management (small rewards for drug-free tests), have the best evidence.^[5]

Mental health. If drug use comes with depression, anxiety, trauma or psychosis, look for a program with a psychiatrist. Our dual diagnosis guide explains what to look for.

How long does drug rehab take?

Residential programs in Thailand are usually priced per 28 days, and many centers offer longer stays. Where centers publish several lengths, the cost per 28 days of a long stay is about 8% to 15% lower than a single 28-day stay.^[11]

NIDA says the right length depends on the person, that the best outcomes come with longer treatment, and that relapse is a signal to restart or adjust treatment, not a failure.^[1] Three months does not have to mean three months in Thailand: a shorter residential stay followed by outpatient care at home also counts.

What does Thai drug law mean for visitors?

The UK government warns that in Thailand even small amounts of illegal drugs can lead to heavy fines or prison.^[7]

The same advice says possessing Class A drugs can carry the death penalty. Cannabis is now limited to medical use with a Thai prescription, and recreational use is illegal.^[7] Rules can change, so check your own government's travel advice before you go.

Thailand's 2021 Narcotics Code moved towards treating people who use drugs as patients and encouraging voluntary treatment.^[8] But drug use is still widely criminalised, and policy researchers say punitive approaches remain.^[9] Being in treatment does not protect anyone who buys or carries drugs.

Prescribed medicines need care too. Under Thai FDA rules, narcotic medicines such as methadone need a permit, and psychotropic medicines such as buprenorphine and benzodiazepines need a doctor's letter for up to 30 days or a permit for 31 to 90 days.^[10] Our medication guide has the details, checked in October 2026.

What does drug rehab in Thailand cost?

The median published price for 28 days of residential addiction treatment is US$11,834, from 8 centers that publish prices on their own websites.^[11]

Published entry prices run from US$8,500 to US$21,933 for 28 days. Only 3 of those 8 centers say detox is fully included, and 6 of 10 centers whose price pages we read charge for medication separately.^[11] Ask for a written quote that lists detox, medicines, hospital care and tax.

Add flights, visas and any time before or after the program. Our cost guide has an estimator, and the Price Index shows the full figures and method.

Does Thailand have government drug treatment?

Yes. The Department of Medical Services runs specialist drug-treatment hospitals under the Thanyarak name, including in Chiang Mai and Khon Kaen.^[13] Their information is mostly in Thai, and fees are published as daily charges rather than packages.^[11]

Methadone was added to Thailand's universal health coverage scheme in 2008, according to a 2017 study of clinics in Bangkok.^[12] That cover is for people entitled to Thai public health care, not for visitors. We have not been able to confirm how a foreign visitor would get methadone in Thailand, so ask a center's doctor before you travel.

Questions to ask a center before you pay

Ask for written answers before you pay a deposit or book flights. A good center will answer clearly and won't pressure you to decide quickly.

1. Is the center licensed, and which doctor is responsible? Check the licence yourself; our safety checklist shows how.
2. How will my withdrawal be managed? Ask what is done on site, when someone is sent to hospital, and who pays.
3. What experience do you have with my drug? Ask how much of the program is specific to opioids, stimulants or pills.
4. Do you allow methadone or buprenorphine? If you take either, ask whether the center's doctor can continue it, and in writing.
5. Is a psychiatrist involved? Ask how often you would see one, and whether that costs extra.
6. What happens after discharge? Ask for an aftercare plan that connects to a doctor or service at home, especially after an opioid detox.
