Australian travelers planning a holiday to Thailand in 2025 should be alert to a major policy shift—Thailand has officially restricted cannabis use to medical purposes, reversing its previously liberal stance on the substance. This significant regulatory update was announced on Tuesday, June 25, by Thailand’s Health Minister Somsak Thepsutin, and it marks a clear break from the more relaxed rules introduced after cannabis was decriminalized in 2022.
The decision introduces strict limitations, including requiring users to have a prescription, restricting THC content to below 0.2%, and effectively banning recreational cannabis use. The changes come amid rising public health concerns and growing political tension over the issue.
What Has Changed in Thailand’s Cannabis Laws?
Just three years ago, Thailand made headlines globally as the first Asian country to decriminalize cannabis, aiming to stimulate the economy, encourage medical cannabis production, and support tourism recovery post-pandemic. However, growing unease over the unintended rise in recreational use, public consumption, and addiction has now led to a dramatic policy U-turn.
Under the newly signed order by the Ministry of Public Health:
- Cannabis is now legal only for medical use
- Users must have a valid prescription from a licensed Thai medical professional
- Cannabis products must contain less than 0.2% THC by weight
- Sales through unlicensed recreational dispensaries are now considered illegal
While an exact implementation date is yet to be confirmed, authorities are urging compliance and warning of penalties once enforcement begins.
Australian Tourists: What You Must Know Before You Go
Smartraveller, the official travel advisory site from the Australian Government, has issued an urgent alert for citizens heading to Thailand. Australians are being strongly advised to:
- Avoid any recreational use of cannabis, even in areas where it previously appeared tolerated.
- Refrain from purchasing cannabis or related products from unlicensed vendors or tourist-focused dispensaries.
- Be aware that possession of cannabis with THC levels over 0.2% could lead to legal consequences, even if unknowingly acquired.
- Consult a Thai-registered doctor if planning to use cannabis for medical reasons.
Australian travelers are also reminded that drug-related offenses in Thailand carry harsh penalties, including imprisonment, fines, and possible deportation.
The Rapid Rise and Fall of Cannabis Freedom in Thailand
Thailand’s brief experiment with cannabis liberalization was groundbreaking. In 2022, cannabis was removed from the country’s narcotics list, and dispensaries sprang up across Bangkok, Chiang Mai, Phuket, and other popular tourist hubs. The aim was two-fold: expand access to alternative medicine and attract international tourists, especially younger travelers with an interest in cannabis culture.
Yet, the open policy soon led to unregulated recreational use, often in public areas. Critics warned that the lack of clear enforcement guidelines had created confusion and allowed abuse to flourish. Rising concerns about addiction, impaired public behavior, and cannabis exposure to minors prompted a national rethink.
According to Thailand’s Office of the Narcotics Control Board, cannabis-related complaints and health emergencies increased significantly between 2023 and 2024, adding pressure on lawmakers to act.
Political Fallout: Parties Divided on Cannabis Policy
The cannabis reversal has also triggered political discord within Thailand’s ruling coalition. The Pheu Thai Party, which currently holds government leadership, spearheaded the reversal. In contrast, the Bhumjaithai Party, a former coalition partner and key architect of the 2022 cannabis decriminalization, strongly opposed the rollback.
The rift between the two parties escalated after a leaked phone conversation involving Prime Minister Paetongtarn Shinawatra and former Cambodian leader Hun Sen reportedly led to the collapse of cooperation between the factions. The Bhumjaithai Party has since withdrawn its support, intensifying the political pressure surrounding cannabis regulation.
Despite the controversy, Health Minister Thepsutin defended the new rules, stating they are necessary to “protect public health, particularly among vulnerable groups and youth.”
Tourism Industry Watches Closely
Thailand’s tourism sector, which had welcomed the influx of “cannabis tourists,” is now adjusting. Many cannabis-themed cafes and dispensaries are being forced to shut down or convert to medicinal-only operations, leaving business owners and international travelers uncertain.
Industry analysts note that this could affect tourist arrivals from countries where cannabis is legalized or culturally accepted, such as Australia, Canada, and parts of the United States. However, officials from the Tourism Authority of Thailand (TAT) insist the nation’s core tourism appeal—its beaches, culture, cuisine, and wellness retreats—remains intact and vibrant.
Tips for Australian Tourists Traveling to Thailand in 2025
If you are planning a trip to Thailand, here’s what Australian travelers should do to stay safe and compliant:
- Stay Updated – Check Smartraveller and Thai government sites regularly for the latest on cannabis laws.
- Avoid Recreational Use – Do not assume cannabis is legal or tolerated simply because it is visible or advertised.
- Consult a Doctor – Only use cannabis with a prescription from a licensed Thai medical provider.
- Avoid Public Use – Even if medically approved, do not consume cannabis in public places or tourist spots.
- Travel Smart – Carry documentation if using cannabis for approved medical purposes, and avoid transporting it across borders.
Conclusion: Respect the Law, Enjoy the Trip
Thailand’s evolving cannabis laws signal a return to cautious regulation, prioritizing public health over unfettered cannabis tourism. For Australian travelers, the message is clear: understand the laws, follow the rules, and avoid assumptions based on past freedoms.
By staying informed, respecting local regulations, and seeking legal guidance if needed, Australian tourists can still enjoy everything Thailand has to offer—from the temples of Chiang Mai to the beaches of Krabi—without running afoul of the law.
