Public Health Minister Anutin Charnvirakul on Wednesday said that further relaxation of cannabis for recreational use is possible in the future if the public accepted it.

Anutin said that legalisation of the recreational use of cannabis in the future could be done if people agree that cannabis use is not harmful.

Mr Anutin insisted the government's medical cannabis legalisation has not been harmful to society since the plant was taken off the country's narcotics list in June.

The Ministry of Public Health has reported only 60 hospital admission cases with severe conditions caused by improper cannabis use from June 6-Aug 16, or one case per day on average, which means nothing among a population of 70 million people, Mr Anutin said.

"I would say some negative cases appeared on the news that are very dramatic -- such as cannabis use in schools or cannabis smells in public places. We have a law to control it under the public health law and the authorities have full right to take legal action against culprits," he said.

Mr Anutin said the exaggerated fear and concern over the negative impacts of cannabis legalisation has been pushed by some groups.
