Health Minister Somsak Thepsutin announced on Tuesday that Thailand would be tightening its restrictions on the sale of cannabis, now requiring users to obtain a prescription first.
Smartraveller has urged Australians to 鈥渆xercise a high degree of caution鈥 when visiting Thailand, especially if using the substance.
鈥淭he use of cannabis is limited to medicinal purposes only,鈥 the site read, adding it must be below 0.2 per cent in weight and users 鈥渕ust have a prescription鈥.
The Thai government order did not specify when the new law would come into effect and is yet to disclose the punishment associated with violating the law.
The move comes three years after the Thailand government announced it would decriminalise the use and sale of cannabis, prompting an increase in tourism and a spate of cannabis-related shops.
Thailand was the first Asian country to decriminalise the use of cannabis however changed its tune after reports that addiction had increased.
鈥淐annabis will be classified as a narcotic in the future,鈥 Mr Thepsutin said.
The Pheu Thai Party, which is in power in Thailand, announced it would scale back its decriminalised stance despite facing resistance from former coalition partner, the Bhumjaithai Party.
Last week, the Bhumjaithai Party cut ties with the Pheu Thai Party following a leaked phone call between Prime Minister Paetongtarn Shinawatra and former Cambodian leader Hun Sen.
