Thailand's Cannabis Future Network has urged three alliance parties not to reinstate the plant as a narcotic drug, as that would lead to more problems.

Prasitchai Nunual, the network leader, wrote on their Facebook fan page on Monday that before the election, the Ad-Hoc Committee on Systematic Hemp and Cannabis Resolution was set up to discuss removing cannabis from the list in an attempt to study the usage of the plant.

According to Mr Prasitchai, the committee consisted of not only experts but also representatives of political parties, including the Move Forward Party (MFP), the Pheu Thai Party and the Prachachart Party, three of the seven allies that signed a working agenda on May 22.

With that said, the three parties' attempt to reinstate cannabis as a narcotic drug appeared contradictory. He said it was for the benefit of the parties, not the country, and, even worse, was not based on the evidence available.

Mr Prasitchai said that a shift in cannabis policy based on public opinion alone might result in an even worse situation later on. He suggested that they review the results of the study once again before thinking of reinstatement.

Meanwhile, cannabis growers in Khon Kaen also called for discussion before any changes are made.

The owner of a cannabis shop in Khon Kaen told the reporters that she was worried about vague legal regulations on cannabis, as they made it difficult for owners.

She said she wished new regulations would focus more on medical uses of the plant as "growers have already invested large amounts in their products".
