SAN JUAN, Puerto Rico — Puerto Rico’s governor on Sunday signed an executive order to authorize the use of medical marijuana in the U.S. territory in an unexpected move following a lengthy public debate.

Gov. Alejandro Garcia Padilla said the island’s health secretary has three months to issue a report detailing how the executive order will be implemented, the impact it will have and what future steps could be taken. The order went into immediate effect.

“We’re taking a significant step in the area of health that is fundamental to our development and quality of life,” Garcia said in a statement. “I am sure that many patients will receive appropriate treatment that will offer them new hope.”

The order directs the health department to authorize the use of some or all controlled substances or derivatives of the cannabis plant for medical use. [Read more from the Associated Press at the Minneapolis Star-Tribune]
