Mom-&-pop Rx

It’s a new twist on pill-pushing: Raid Mom and Dad’s medicine cabinet and then sell the swiped prescription goodies on the Internet.

Twenty-one people — including an NYU grad student who’s a former intern to a US senator — have been netted in a yearlong Craigslist sting that went down in coffee shops, bookstores and parks across the city, authorities said yesterday.

Some of the suspects — a bizarre mix that also included a celebrity photographer and a former Manhattan public-relations whiz — got prescription drugs such as Xanax, Valium and Adderall from the medicine cabinets of relatives, friends and co-workers or their own prescriptions, authorities said.

They then offered them for sale on Craigslist in individual low-level deals, officials said. They were not part of an organized ring.

One ad — placed by a self-described “friendly NYU student” — offered “pain and anxiety relief’’ and signed off with “perc roxy” and a smiley face.

“I wouldn’t pretend to know their motivation,” said city Special Narcotics Prosecutor Bridget Brennan, whose office ran the sting with Manhattan South narcotics detectives.

Among those arrested were NYU grad student Yasmin Malhotra, 25, a former intern for Sen. Robert Menendez (D-NJ) and the United Nations.

Malhotra — daughter of wealthy Princeton philanthropist and public speaker Rajiv Malhotra — was nabbed in SoHo in her car after she allegedly agreed to sell an undercover cop 20 Xanax pills for $100.

There was evidence she had numerous customers, a source added.

Her dad, outside his Princeton, NJ, mansion yesterday denied that his daughter was a drug dealer.

“That’s something I haven’t heard,” he said.

Nicholas Baily, 37, a former p.r. man who wrote Huffington Post columns, was busted for allegedly selling $300 worth of Adderall to cops in June, law-enforcement sources said.

His wife declined to comment outside of their three-story Brooklyn Heights brownstone, saying only, “He does not live here right now.”

Charlyn Zlotnick, 62, a rock photographer whose work has appeared in The New York Times, was busted for allegedly selling $1,000 worth of Adderall to undercover cops in the East Village from December to July.

A woman who answered the door at her Alphabet City apartment refused to comment.

An alleged coke dealer, Parris Daniels, 44, of Washington Heights, also was arrested yesterday after the sting.

He pleaded not guilty.
