Rumors had been swirling that Zac Efron's stint in rehab was for alcohol abuse, but that appears to have been completely false. TMZ reported late on Tuesday, Sept. 17, 2013, that he ended up going to rehab for what is being called a serious addiction to cocaine.
Earlier this year, Efron completed his time in rehab after the cocaine addiction appeared to get out of control while he was on the set of Seth Rogen's film, "Neighbors." The film was shot in a small period of time back in April of 2013.
Efron was one of the stars of the film and was said to be a no-show on a number of days of filming for "Neighbors."
One source connected with the film told TMZ that "It was common knowledge he was struggling with cocaine."
Others have said that cocaine wasn't the only drug that Zac Efron was messing with. While it was his main choice, Efron also used "Molly" which is a very pure form of Ecstasy.
No response has been made by Efron or his people yet.
Sources have also told TMZ that earlier in 2013, Efron was with a number of friends in a room at the SkyLofts at the MGM Grand in Las Vegas. Apparently they went on a sort of cocaine binge and caused close tot $50,000 in damage to the room.
