New York Governor Andrew Cuomo said cannabis will be legal by July 1, 2018.
However, cannabis will not be legal in the state unless Governor Cuomo signs a law legalizing the drug, which the governor has said he is unlikely to do.
The move comes after the state passed the first of two medical marijuana laws this year.
The legislation allows patients to possess up to six ounces of cannabis, grow up to three plants, and use it to treat debilitating conditions such as multiple sclerosis and cancer.
It also allows adults to purchase cannabis at licensed dispensaries.
The state has also approved the cultivation and sale of recreational cannabis.
The announcement by Cuomo comes after a string of state-sanctioned marijuana sales by small businesses and people in New Jersey and Massachusetts.
The governor’s announcement comes after he and Democratic lawmakers last month voted to legalize marijuana for recreational use in New Hampshire and in Massachusetts.
