About the clinic

One Step Rehab Thailand in Chiang Mai provides residential drug addiction treatment for substances like opioids, cocaine, and methamphetamine. Programs typically cost around $8,500 for the first 28 days, while a full 90-day stay runs around $22,500. This boutique 14-bed facility holds JCI accreditation and a Thai Ministry of Public Health License, maintaining a 1:1 staff-to-client ratio.

Dr. Worapakthorn Kongpesalaphun leads the medical team as a consultant psychiatrist with over 20 years of experience. A graduate of Rangsit University, Dr. Worapakthorn Kongpesalaphun specialized in psychiatry at the Somdet Chaopraya Institute. Dr. Worapakthorn Kongpesalaphun manages the detox protocols and dual diagnosis screenings for conditions like PTSD and ADHD. This medical oversight allows the clinic to handle complex withdrawal cases safely on-site or through a partner hospital for severe ICU-level monitoring.

Diagnostics and assessment

The recovery process starts with a confidential clinical assessment before the patient arrives. This review determines medical eligibility for on-site detox and evaluates substance use history. Upon intake, the medical team performs the following:

Withdrawal severity scoring. Doctors use CIWA-Ar for alcohol or COWS for opioids to monitor symptoms.
Dual diagnosis screening. The team identifies underlying issues like depression, anxiety, or ADHD.
Psychiatric evaluation. Dr. Worapakthorn Kongpesalaphun creates a personalized medication management plan.

Treatment options

The clinic uses the Recovery Zones method, combining evidence-based therapy with physical rehabilitation. Stays range from 28 to 90 days to provide enough time to rebuild healthy reward pathways. Treatment methods include:

Medically supervised detox. The team uses buprenorphine induction for opioids and benzodiazepine tapers to manage withdrawal safely.
Evidence-based therapy. Patients participate in daily group sessions and weekly individual counseling using CBT, DBT, and EMDR.
Holistic and fitness programs. The facility features a Muay Thai ring, gym, pool, and yoga to restore physical health and discipline.
12-month online aftercare. Patients receive a full year of free weekly online group support after leaving the center.

Residential package details

The program fee covers the essential needs for a focused recovery journey. Patients stay in private en-suite rooms within a structured environment. The package includes:

Medical and psychiatric oversight. Regular check-ins with Dr. Worapakthorn Kongpesalaphun and the nursing team.
Nutrition and wellness. All meals are included, alongside access to mindfulness-based relapse prevention and breathwork.

One Step Rehab Thailand: more details about the clinic

Thailand, Chiang Mai

One Step Rehab Thailand is a private, owner-operated residential addiction treatment center. It is located in the Mae Rim District near Chiang Mai. Alastair Mordey founded the facility in 2013. It offers 14 beds for personalized recovery. The clinic is licensed by the Thai Ministry of Public Health.

Accreditations and Clinical Standards

The facility holds JCI accreditation, meeting international healthcare quality standards. It avoids large-scale "production line" care. Founders work directly on-site to oversee every resident's progress. The clinic combines medical stabilization with evidence-based psychotherapy and structured daily routines.

Addiction Treatment and Recovery Programs

One Step Rehab treats various substance use disorders. These include addictions to alcohol, cocaine, opioids, methamphetamine, and benzodiazepines. The clinical team addresses polysubstance use through an integrated approach.

The core program uses Recovery Zones, a structured system targeting compulsive behaviors. Specialists apply several evidence-based methods:

Cognitive Behavioral Therapy (CBT)
Dialectical Behavior Therapy (DBT)
EMDR for trauma processing
Motivational Enhancement Therapy (MET)
Family systems work

Residential stays require a minimum of 28 days. Many residents extend to 60 or 90 days. This gives psychological patterns and withdrawal symptoms time to stabilize. The first month focuses on detox and stabilization. Later stages emphasize habit rehearsal and long-term sobriety planning.

Psychiatrists provide dual diagnosis care for co-occurring mental health conditions. Dr. Worapakthorn Kongpesalaphun leads medication management. He has 20 years of experience and trained at the Somdet Chaopraya Institute of Psychiatry. Dr. Naranchaya Sriburapar, a Clinical Psychologist, provides structured assessments for ADHD and PTSD.

Physical Rehabilitation and Wellness

Recovery includes physical restoration and lifestyle stabilization. The clinic has an on-site training center with a full-size Muay Thai ring. Licensed trainers lead sessions focused on conditioning and body awareness. These activities help restore endorphin levels naturally during recovery.

Other supportive therapies include:

Mindfulness and breathwork
Trauma release exercises (TRE)
Sleep optimization and circadian stabilization
Nutritional supplementation and planning
Outdoor therapy including hiking

These methods complement clinical therapy to address addiction's physical impact.

Services for International Patients

One Step Rehab supports families living overseas. The counseling team conducts joint family sessions via video calls. These workshops focus on setting boundaries and supporting recovery from a distance. The clinic performs confidential pre-arrival assessments to determine medical eligibility for on-site detox.

Support services for travelers include:

Free initial clinical review
Airport pickup and arrival support
Laundry services for residents
Private air-conditioned rooms with en-suite bathrooms

Long-term recovery is supported by 12 months of free online aftercare. This includes weekly Saturday group sessions and alumni community access. Aftercare planning begins in the second week of treatment. Counselors help residents map triggers and arrange support in their home communities.

One step is a first rate rehab. Professional staff, beautiful surroundings. Amazing place to recover. What stood out for me was the emphasis on physical health and mental health being equally important. Diet is also a big part of what the do. These are the elements that a lot of rehabs miss in my opinion.

I honestly couldn’t recommend One Step Rehab enough. From the moment I arrived, the whole team made me feel welcome, supported and comfortable. The staff are incredibly friendly, professional and genuinely care about the people they’re helping. What really stood out to me was how personalised the experience is. It doesn’t feel like you’re just another person going through a program — the team actually takes the time to understand you, your goals and what you need to work on. The combination of the rehab program, exercise, Muay Thai training and the overall environment made a huge difference for me. Being able to train, stay active and work on myself while having the right support around me was something I really appreciated. The facilities and location are great, but honestly, it’s the people that make One Step what it is. Everyone I dealt with was approachable, respectful and willing to help whenever I needed it. I came here hoping to make some serious changes in my life, and I’m leaving with a completely different mindset and a much more positive outlook. I’m genuinely grateful to everyone at One Step for the time, effort and support they’ve given me. If you’re considering coming here, I’d definitely recommend giving them a chance. It’s been a really important experience for me, and I’m very glad I made the decision to come.

I have just spent 2 months here and thought it was absolutely amazing! The staff were very friendly and attentive, the accommodation was very comfortable and private, and the amount of activities on offer is fantastic. All the staff were very friendly and helpful and the counsellors and support workers were very talented with lots of knowledge and experience to help me in my recovery. I feel like I have left One Step with a large set of tools that will help me stay sober and I look forward to a new chapter in my life. Thank you very much everyone ❤️

Life Changing Experience. I spent one month at One Step Thailand for my treatment and I am incredibly grateful for my time here. The clinical team and the support team are exceptional. Their expertise, compassion, and constant dedication made me feel safe and supported throughout my entire recovery journey. Not once was i made feel unwelcome and uncomfortable. The facilities are top-notch. The whole area is kept spotless and the rooms are very comfortable and modern. I am not a huge fitness person but the sports facilities are perfect. Training with their highly professional Muay Thai instructors was a major highlight of my stay and a huge help in my physical recovery. The tropical outdoor pool area, tennis and pickeball courts are also maintained at a 5 star level. If you or a loved one are looking for a professional, clean, and deeply supportive environment to heal, I cannot recommend One Step Thailand enough. Thank you to the entire team for preparing me for my bright future.

Truly an amazing experience. I’ve been to treatment several time and this by far was the most positive experience I’ve had. The perfect balance of counseling and healthy activities to keep you busy. All the counselors and staff are in recovery and I never felt talked down to. The meals were delicious and the accommodations fantastic. Can’t recommend this place enough.
