Two-thirds of Mexicans are against decriminalizing marijuana, according to an opinion poll published on Tuesday, just days after a Supreme Court ruling that opened the door to an eventual legalization.

Some 66 percent of people polled in the telephone survey by El Universal newspaper opposed legalizing the drug. But 63 percent said they backed a wide-ranging debate on marijuana legislation in Mexico, which has suffered a decade of vicious drug violence that has killed tens of thousands.

Last week, Mexico’s Supreme Court ruled to allow four plaintiffs to grow and smoke pot recreationally in a decision that could open the door to legalization.

But any legalization is likely some time away.

It would take four more consecutive decisions of the same kind, or eight of the 11 permanent justices to agree, for the Mexican Supreme Court’s ruling to set an official precedent and force the government to review the law. [Read more at Reuters]
