Thailand Reverses Cannabis Decriminalization: Prescription‑Only Access Returns Amid Tourism Concerns

Thailand has abruptly reversed its 2022 cannabis reform, once celebrated across Southeast Asia—reinstating strict controls and prescription-only access to curb unregulated use and youth exposure.

Backtracking after bold reform

In 2022, Thailand became the first Asian country to decriminalize cannabis and open recreational access, with over 18,000 shops emerging nationwide. Now, a June 2025 order reclassifies cannabis buds as narcotics once again, limiting sales exclusively to medical dispensaries and requiring prescriptions from licensed doctors  .

Politically driven shift

The policy U-turn follows the Pheu Thai Party’s move toward tighter drug laws after the Bhumjaithai Party left the governing coalition in mid-June, freeing the government to act on its pledge to restrict cannabis to medical use  .

Tourism at risk

The cannabis boom had attracted travelers seeking weed-friendly vacations. With shops and festivals popping up in Bangkok, Phuket, and Pai, some regions may face backlash as tourists lose access. Australia’s travel advisory already cautions visitors following the new restrictions  .

Economic and industry impact

Thailand’s cannabis sector—once projected to reach as much as $1.8 billion—now braces for a downturn. Small dispensaries and farmers warn that strict licensing and prescription mandates will push many out of business and send consumers underground ().

Public health and youth protection

Thai authorities cite rising youth usage, addiction rates, and smuggling tied to tourism. Violators of the new rules face as much as one year in prison and fines up to 20,000 baht. Supporters argue the reform is essential for public health balance  .

Activist backlash and protests ahead

The “Writing Thailand’s Cannabis Future Network” and other advocacy groups have vowed to protest on July 7, calling the move a political power play that will harm the sector’s legitimacy  .
