Governor Andrew Cuomo signed a bill legalizing recreational marijuana on Wednesday, making New York the 16th state to do so. Cuomo signed the bill a day after it passed in the State Legislature. Parts of the law went into effect immediately, as the New York Times explains:

Individuals are now allowed to possess up to three ounces of cannabis for recreational purposes or 24 grams of concentrated forms of the drug, such as oils.

New Yorkers are permitted to smoke cannabis in public wherever smoking tobacco is allowed, though localities and a new state agency could create regulations to more strictly control smoking cannabis in public. Smoking cannabis, however, is not permitted in schools, workplaces or inside a car.

Other changes will go into effect in the coming months when officials create the regulatory framework that will govern every aspect of a brand new, highly regulated market.
