Sources told TMZ.com that the ‘High School Musical’ star’s coke problem spiraled out of control during the filming of Seth Rogen’s movie ‘Neighbors’.
Insiders have claimed that the handsome hunk was also a no-show on a number of days while the film was being shot.
Meanwhile, a source connected with the movie told the publication that it was common knowledge that Efron was struggling with cocaine.
The 25-year-old actor’s problem was rooted in cocaine, but he has also experimented in Molly, a pure form of Ecstasy, the insider added.
