Yesterday the world found out that former High School Musical star Zac Efron checked into rehab about 5 months ago for his cocaine and molly addiction however we are now learning that this was actually his second stint in rehab this year alone!!!  Supposedly he has been doing cocaine for more than 2 years and tried to clean himself up back in March.  That’s the first time he went to rehab.  Then in April, he relapsed while filming Seth Rogen’s film Neighbors.  He wasn’t showing up on set and pretty much everyone noticed he had a problem.  That’s when he checked into rehab for the second time. So why did Zac start abusing drugs?  Sources say he has significant issues with his parents, he is upset about his movie career which hasn’t had much success since High School Musical, and he has “girl issues” although we’re hearing they have nothing to do with his break-up with Vanessa Hudgens.  Plus, he’s been hanging out with a bad group of friends who introduced him to the world of cocaine.
