Cannabis in Thailand 2025: What You Need to Know Now

In just a few short years, Thailand went from being Asia’s most progressive cannabis market to tightening its laws again. As of 2025, many people—locals and tourists alike—are understandably confused.
Can I still buy cannabis? Do I need a prescription? Is CBD legal?

This article gives you a clear overview of the current legal status, what’s changed in 2025, how it affects consumers and businesses, and how you can continue to access cannabis safely and legally in Thailand.

The Big Change: Prescription-Only, No Edibles, and No Smoking Lounges

As of June 28, 2025, the Thai government has reclassified cannabis flower (buds) as a controlled herbal substance. Cannabis is no longer decriminalized for general use and is now regulated under the Traditional Thai Medicine (TTM) framework.

To legally purchase cannabis, you now need a valid medical prescription from a licensed Thai healthcare provider, such as:

• General medical doctors
• Dentists
• Traditional Thai medicine (TTM) practitioners
  
  

Prescriptions must:

• Clearly state your diagnosed condition
• Include the form of cannabis (e.g., dried flower, oil)
• Specify dosage and frequency
• Be renewed every 30 days
  
  

What’s No Longer Allowed

The new regulations prohibit:

• Smoking cannabis in public or semi-public spaces (parks, cafes, cars, beaches, etc.)
• Selling cannabis without a medical license or pharmacy-level operation
• Edible cannabis products for sale
• Selling via vending machines or online platforms
• Marketing cannabis for recreational use or unapproved medical claims
• Possessing cannabis without a valid Thai prescription
• Importing/exporting cannabis or hemp products without proper licensing

Penalties include fines up to 25,000 THB or imprisonment, depending on the violation.

What’s Still Legal

Cannabis can still be used for medical purposes, under professional supervision.

Approved conditions include:

• Insomnia
• Loss of appetite
• Migraines
• Parkinson’s disease
• Chronic pain
  
  

Cannabis flower remains legal for use when prescribed and can be purchased from certified dispensaries. These dispensaries must verify your prescription and log your usage history for compliance.

For Tourists and Foreign Visitors

Thailand still welcomes medical cannabis tourism, but under strict new rules:

• You must visit a Thai-licensed clinic to obtain a prescription.
• Foreign-issued prescriptions are not valid in Thailand.
• Possessing cannabis without a Thai prescription is illegal.

Tip: At Wonderland Clinic, you’ll receive a medical certificate that you can carry with you as proof of your prescription.

Travel tips:

• Bring any relevant medical records to help with your consultation.
• Book a clinic appointment in advance.
• Always keep your medical certificate or PorTor 33 (ภท.33) copy on hand.
  
  

Why the Law Changed

The government cited concerns over:

• Inadequate research and regulation
• Misuse and societal impact
• Lack of a formal Cannabis Act to govern responsible access
  
  

This new framework aims to prioritize public health, patient safety, and international credibility, with cannabis use returning to a strictly medical context.

However, responsible operators—including farms and dispensaries—have long called for regulation. Many, like us, have consistently provided GACP-certified, safe, and lab-tested flower, and are now adapting quickly to comply with the new requirements.
