New York’s new governor, who disclosed last week that he and his wife both committed adultery several years ago, said today that he used cocaine in his 20s and smoked marijuana when he was younger.

In reference to cocaine, Governor Paterson, 53, said in a television interview that he “tried it a couple of times” when he was “about 22 or 23.”

“And marijuana probably when I was about 20,” he said on the NY1 cable news station. “I don’t think I touched marijuana since the ’70s.”

“More Americans have tried a lot more during that period of time and gone on to lead responsible lives and hopefully have lived their lives to their fullest,” he said.

Mr. Paterson was lieutenant governor under Governor Spitzer, who resigned last week amid a prostitution scandal.

Last week, Mr. Paterson and his wife, Michelle Paterson, disclosed they each had strayed from the marriage years ago. The couple were separated for a “couple years” at the time, David Paterson said today.

In today’s interview, Mr. Paterson pointed out that he had acknowledged to a television journalist in 2006 that he had used illegal drugs.

The NY1 interviewer, Dominic Carter, noted that few people paid attention to Mr. Paterson’s revelation then because he was running for lieutenant governor.
