Is that the reek of pot in the air — or hypocrisy? We ask because Gov. Andrew Cuomo and Mayor Bill de Blasio are trying to have it both ways on marijuana.

Cuomo plainly ordered his health commissioner, Howard Zucker, to issue a report calling for legalization. Zucker disclosed Monday that he’s about to recommend it, saying “new facts” show “the pros outweighed the cons.”

But he hasn’t released it yet — so Cuomo can insist he’s still waiting for it and so won’t try to get the Legislature to act on it this year.

After lawmakers go home this week, expect the report to land and Cuomo to embrace it — neatly removing an issue pushed by his challenger, Cynthia Nixon.

And never mind that this leaves the gov with the chance to discover yet more “new facts” and change his mind back after the September primary — or anytime before the Legislature comes back into session.

After all, just months ago he was still calling marijuana “a gateway drug.” And he took great care that New York’s medical-marijuana law didn’t OK the smokable stuff.

De Blasio, meanwhile, joined Police Commissioner James O’Neill on Tuesday to announce that, starting in September, most New Yorkers caught smoking grass in public will get tickets, rather than face arrest. (Exceptions include those with a criminal record and immediate public-safety threats.)

Never mind that, as even the mayor’s office concedes, it’s “extremely rare” for anyone to be imprisoned for possession. Or that the mayor not long ago insisted such arrests were at “a normal level.”

No, this is meant to address the racial disparity in arrests — which, as we’ve long maintained, is caused by factors other than supposedly bigoted law enforcement.

Anyway, it won’t satisfy the critics. City Councilman Donovan Richards used the press conference to give another rant about the NYPD’s “sordid history of injustice” and its “strategies that perpetuate racial bias.”

City and state, New York plainly needs an honest conversation about marijuana laws. Too bad that’s the last thing the top politicians want to offer.
