Gov. Cuomo’s push to legalize recreational marijuana is becoming a potent political issue in the city’s suburbs, particularly Long Island.

Rob Trotta, a Republican candidate running for Suffolk County executive, is campaigning against legalization.

Trotta, a Suffolk legislator and retired cop who announced his candidacy last week, wants to prohibit recreational weed from being sold anywhere in the county, saying he doesn’t want to promote reefer madness.

“We can’t have people driving around stoned all the time,” Trotta said in an interview. “This is about one thing and one thing only: money.”

Cuomo’s plan would impose 22 percent in taxes on the manufacture and sale of marijuana products.

Suffolk County Executive Steve Bellone, a Democrat and Cuomo ally seeking re-election to a third term this fall, has not taken a position on the burning issue.

The governor himself anticipated resistance to his plan in some parts of the state. It allows counties or cities with more than 100,000 residents to opt out of selling weed within their boundaries.

North Hempstead in Nassau County, LI, voted last week to bar the sale of marijuana. Meanwhile, Hempstead is considering imposing a one-year moratorium.

Mayor de Blasio in December endorsed weed legalization after years of having doubts on the matter.
