Arizona’s southern neighbor will be legalizing recreational marijuana by April 30th. A bill legalizing the possession of up to 28 grams of marijuana just moved one step closer to approval and now heads to the full Senate for a vote.

A majority of the lawmakers voted in favor of the new bill, Mexico News Daily reported. The bill would also allow medical marijuana patients to grow up to 20 plants.

Due to Mexico’s large population a recreational marijuana market in the country would be vast. Mexico currently has a population of around 130 million people, whereas, by contrast, Canada has around 38 million.

In October, Mexico’s Supreme Court ruled that prohibiting recreational marijuana is unconstitutional and gave Mexican lawmakers an April 30th deadline to pass legislation legalizing the substance.
