After just three years of one of the world’s most liberal cannabis policies, Thailand has reversed course, reclassifying cannabis as a controlled medical substance and banning all recreational use. As reported in The Washington Post’s widely read piece, “Thailand reverses course on decriminalized marijuana”, this pivot represents a dramatic policy U-turn—one with wide-reaching effects for public health, business, and international reputation.
📜 From Trailblazer to Tight Control: A Timeline
In 2022, Thailand became the first Asian nation to decriminalize cannabis, triggering a surge of optimism among entrepreneurs, tourists, and patients. Cannabis cafes, dispensaries, and farms rapidly appeared—especially in cities like Bangkok, Chiang Mai, and Pattaya.
But the lack of regulatory infrastructure quickly led to public confusion and legal gray areas. Recreational use was widespread, despite no formal legislation allowing it. The original goal—promoting medical use and boosting agriculture—began to fade under a booming, loosely regulated retail scene.
In June 2025, under pressure from conservative lawmakers, medical authorities, and public backlash, the Thai government formally reversed its stance.
🔒 The New Rules: Medical-Only Access
Under the new law:
Cannabis is now classified as a controlled herb, subject to tight restrictions.
Recreational use is illegal, even in private settings.
Only patients with valid prescriptions from certified Thai medical professionals may legally obtain cannabis.
Dispensaries must convert into licensed medical clinics or cease operations.
Cultivation is still permitted, but only for licensed growers following GACP standards and linked to medical institutions.
