Srettha also ordered local authorities to suppress criminal activities linked to the illegal drug trade and demanded to see progress within 90 days.
After cannabis was decriminalized in 2022, it was initially said that it would be allowed only for medicinal use, but in practice the market was unregulated. It has prompted public backlash and concerns over misuse and crime.
Decriminalization was spearheaded by the Bhumjaithai Party, whose stronghold is in the impoverished northeast where it promised farmers cannabis would be a new cash crop.
In the 2023 elections, all major parties — including Bhumjaithai — promised to restrict cannabis for medical use.
Cannabis advocates and entrepreneurs have opposed a radical rollback, which they claimed would be damaging to the economy. Legal cannabis has fueled Thailand's tourism and farming sectors and spawned thousands of cannabis retails ranging from shops, trucks to market stalls all over the country.
