Troubled Met legend Dwight Gooden’s battles with drugs and booze are “disappointing,” his son told The Post.

“Doc” Gooden was busted last month in New Jersey for cocaine possession and driving under the influence.

The June 7 arrest is the latest chapter in a struggle with substance abuse that has plagued the pitching great for decades.

It’s an “unfortunate situation,” said Dwight Gooden Jr., who called it “very disappointing.”

But the son, who briefly spoke outside of his dad’s Piscataway, NJ, home on Friday, made clear he didn’t take after his father.

“I’m not him. I don’t live that life, never did. I got my own children,” he said. “I don’t know what to say.”

Gooden Jr. declined to answer any other questions.

The elder Gooden, 54, was once one of the most promising baseball players of the 1980s.

He won the National League Cy Young Award in 1985 and went on to help the Mets win the World Series in 1986.

Gooden’s downward spiral began a year later when he tested positive for cocaine during a Mets training camp. He checked into rehab that April. A shoulder injury in 1989 led to a steep decline in his play.

“The Mets aren’t sure what they have in Gooden anymore,” wrote Sports Illustrated in a 1993 profile titled “From Phenom to Phantom.”

The team’s assistant vice president of operations, Gerry Hunsicker, told the magazine at the time that he didn’t “see [Gooden] getting back to where he was early in his career.”

Drug use surfaced again in 1995, when Gooden was suspended for an entire season after testing positive for cocaine. He formally retired in 2001.

Gooden famously missed the Amazin’s 1986 ticker tape parade, but by 2017 had appeared to be on the road to redemption.

He joined in a City Hall celebration that year of the 1986 squad with teammates Darryl Strawberry, Jesse Orosco and Bobby Ojeda.

At the time, Gooden said he was clean and sober.

“Today I can close that wound. I can fill that void with love, and peace and joy,” he said during a ceremony giving the players a key to the city.

Gooden is due in court on July 23.
