PATERSON -- The city's school district is investigating a rap video, filled with drug references and a stripper, that was filmed at one of its high schools, officials confirmed.

City native and rap superstar Fetty Wap released a music video last week for his latest single, "Wake Up," filmed at Eastside High School, according to social media posts by the rapper.

The district confirmed to NJ Advance Media late Tuesday night that the video was shot at the school and that they are now investigating who allowed it.

"As there are procedures that must be followed in securing the use of our facilities, whether all procedures were followed is in question and being investigated - and will be addressed as a personnel matter," Terry Corallo, the district's spokeswoman, said.

"The district does not endorse the content of this video," Corallo said.

The video, a stoner's anthem released on April 20, the unofficial cannabis connoisseur's holiday, has numerous drug references and features a scantily clad stripper twerking on a pole inside a classroom.

The song's hook, "Let's get Wiz Khalifa high/Get meditated over medicated," refers to smoking marijuana like rapper Wiz Khalifa, who often raps about the drug and even has his own strand of marijuana, according to genius.com.

Numerous banners and posters seen in the video read, "Go Team Kush," a reference to a strain of marijuana. Towards the end of the video, a woman, presumably a teacher, takes an apple from her desk and uses it as a bong.

"I went back to my old high school to shoot this video," reads a message from the rapper as the video opens. "A nobody, high school dropout now known worldwide as Fetty Wap. Celebrate every day, roll something up and define your own path."

Corallo did not disclose exactly when the video was shot but said the district has determined that the video was shot during non-instructional hours and that no students participated in the video.

Recently the school district has struggled with a 70 percent increase in positive drug test results among students, many of them from marijuana and at East Side High School.

On his Instagram account, Fetty Wap, aka Willie Maxwell, dedicated the song to the graduating class of 2016.

"This song is for everyone that celebrates 4/20 all year but still passes that math test," wrote Maxwell. "This song is for everyone that might not be in the top of their class or most popular but you still know where you're headed, just riding on your own path."

The Paterson school district recently underwent a round of layoffs as it struggles financially. Corallo did not respond to questions about payment to shot the video.

A publicist for the rapper did not return requests for comment.

Last summer, Maxwell preformed a free concert for city high school students, which featured Mayor Joey Torres dancing on stage.
