(CNN) Thailand's interim parliament voted to allow the use of medical cannabis, one of the senators who worked on the bill told CNN on Tuesday. Recreational use of the drug remains illegal.

Lawmaker Somchai Sawangkarn said the passing of an amendment to allow medical marijuana in the country "could be considered as a New Year gift to Thais." "The amendment (on the Narcotics Bill) was passed the second and third readings today. And will become effective once it is published on the Royal Gazette," he said."

The National Legislative Assembly's 166 members voted in favor of the change and there were no votes objecting to the motion. There were 13 members who abstained from the vote.
