HIGH School Musical star Zac Efron was reportedly treated for drug abuse during his stint in rehab, it has been claimed.
The former Disney star entered rehab five months ago, it has been reported.
The news emerged late last night, with a number of media outlets claiming it was for alcohol abuse.
However, TMZ.com has now reported that Efron was treated for recreational drug abuse.
They reported that Efron (25) underwent treatment for problems with cocaine.
They also alleged that he had been using a drug nicknamed ‘Molly’ – a form of ecstasy popular on the club scene.
TMZ claimed that Zac’s problems came to a head in April when he was filming forthcoming ‘Neighbours’ alongside Seth Rogan.
The production had a tight filming schedule and Zac was a ‘no-show’ on set for a number of days.
The website also claimed that Zac and a group of friends went on a “coke rager” while partying at the MGM Grand in Las Vegas earlier this year.
It was reported that the group cost $50,000 worth of damage to their suite.
A representative for Efron has yet to comment on the allegations.
Zac (25) shot to fame for his role in the hugely popular Disney series ‘High School Musical’.
He played clean-cut heart-throb Troy Bolton and starred alongside his then girlfriend Vanessa Hudgens, who played his on-screen love Gaby.
Since the release of ‘High School Musical 3’ in 2009, Efron has starred in a number of films.
He split from Hudgens after five years together in 2010.
Zac’s reported drug problems will come as a shock to many of his young fans.
Earlier this summer, Canadian actor Cory Monteith (31) was found dead in his hotel room in Vancouver after overdosing on heroin.
The troubled Glee star had two stints in rehab – the first ten years ago, and the second stay earlier this year.
However, many believed he had turned a corner.
Cory, who played Finn Hudson in the hugely popular Fox series, died of a toxic combination of heroin and alcohol in July.
