Ye Htet Zaw, 25, was arrested at construction workers’ living quarters in Moo 4, Samui district, during a routine visit by Immigration police and soldiers.
They decided Ye was behaving suspiciously and noticed the two bottles of brown liquid he was holding.
A test established the liquid was made from kratom leaves (Mitragyna speciosa), a Category 5 narcotic. They even found the pot he used to brew up his potion.
Ye said he worked as a house cleaner and came to stay at the camp with his friend, with whom he bought his kratom leaves at a grocery store.
