Thailand on Tuesday became the first country in Asia to approve the de facto decriminalization of marijuana, though authorities have left a grey area around its recreational use.

Health Minister Anutin Charnvirakul announced that the Narcotics Control Board had approved the dropping cannabis from the ministry’s list of controlled drugs.

The delisting by the ministry’s Food and Drug Administration will now need to be formally signed by the health minister and enters into effect 120 days after its publication in the government gazette. It follows the removal of cannabis — a plant species to which both marijuana and hemp belong — last month from the list of illegal drugs under Thailand’s Narcotics Law.

Police and lawyers contacted by The Associated Press said it was unclear if possession of marijuana would no longer be an offense subject to arrest. A tangle of related laws means that production and possession of marijuana remains regulated for the time being, leaving the legal status of recreational marijuana use in a grey area.

The Health Ministry measure retains on its list of controlled drugs parts from the cannabis plant that contain more than 0.2% by weight of tetrahydrocannabinol, or THC, the psychoactive ingredient that gives users a high.

Thailand in 2020 became the first Asian nation to decriminalize the production and use of marijuana for medicinal purposes. [Read more at The Public’s Radio]
