Community-Led Kratom Decriminalization Model in Southern Thailand Expanded to 135 Villages After Successful Pilot

Why it matters

Thailand criminalized kratom in 1943 despite centuries of cultural use, creating tension with local communities who never viewed it as a drug. This study documents how those communities developed their own alternative governance model — one that has since been adopted across 135 villages nationwide.

The big picture

As Western governments struggle to regulate kratom through prohibition or pharmaceutical frameworks, Thailand's community-based control model offers a third path: treating kratom as a culturally embedded plant requiring community governance rather than criminal law. Thailand formally decriminalized kratom in 2021, the same year this study was published.

Key findings

• • Most residents surveyed (across 457 local respondents, 104 students/teachers, and 1,058 online respondents) supported decriminalization of both kratom cultivation and consumption
• • Most common reasons for supporting decriminalization: kratom's benefits for work productivity and health
• • Participants had more positive attitudes toward fresh kratom leaves than toward decoctions, which were viewed as more potent and potentially harmful
• • A community consensus framework for kratom governance was piloted in Donsai village (127 households), then adopted across Tambon Namphu sub-district, and ultimately expanded to 135 villages across Thailand
• • Thailand's 1943 criminalization of kratom was economically motivated — it competed with opium tax revenues — not based on safety evidence

What they say

Mixed-methods study using participatory action research; face-to-face surveys (n=561 local), online surveys (n=1,058); focus groups and in-depth interviews; Chulalongkorn University Social Research Institute; International Journal of Drug Policy, 2021.

Bottom line

A community-led regulatory framework for kratom — built around cultural rights and local governance rather than prohibition — successfully scaled to 135 Thai villages, suggesting a replicable model for other countries navigating kratom policy.
