Suriya Petchseng was caught with four kilos of kratom (Mitragyna speciosa) and several bags and bottles of kratom drinks in his possession.
The 25-year-old suspect has confessed to selling each bag for Bt50 and each bottle for Bt100.
Muang Krabi district chief Satta Thongkham said relevant authorities would continue a serious crackdown on drugs, including kratom.
Several young people in Krabi have reportedly become addicted to kratom, as sellers have made it more convenient to consume the drug.
