Thailand approved marijuana for medical use and research on Tuesday, however recreational use of the drug remains illegal.
The National Legislative Assembly's 166 members in Thailand voted in favor of the change before the New Year's holidays. 13 members abstained from the vote but nobody voted against.
This makes Thailand the first country in Southeast Asia to allow the use of medical marijuana.

"This is a New Year's gift from the National Legislative Assembly to the government and the Thai people," said Somchai Sawangkarn, chairman of the drafting committee, in a televised parliamentary session.
The amendment will become law when it is published in the government gazette, the Bangkok Post reported.
Battle against marijuana
Thailand has the largest prison population in Southeast Asia, and the sixth-largest in the world. Inmates convicted of minor drug offenses make up the largest percentage of that population, according to VICE News.
In the past, Thai police would burn marijuana, and other drugs, confiscated during busts in a massive bonfire each year.

Only 15 years ago, the country embarked on its own Duterte-style war on drugs that left hundreds of alleged drug dealers dead, including several weed dealers.
But in September, police handed over 100 kilograms of marijuana to medical researchers to use in their studies instead.
Controversy with legalization
In Thailand, the main controversy with legalization involved patent requests by foreign firms that could allow them to dominate the market, making it harder for Thai patients to access medicines and for Thai researchers to access marijuana extracts.

"We're going to demand that the government revoke all these requests before the law takes effect," said Panthep Puapongpan, dean of the Rangsit Institute of Integrative Medicine and Anti-Aging.
Some Thai advocates hope that Tuesday's approval will pave the way for the legalization for the drug's recreational use.

Canada and Uruguay are among those to have legalized it, including for recreational use.
