Zac Efron completed a stint in rehab earlier this year for what was an undisclosed issue that snowballed during the filming of "Neighbors" with Seth Rogen.

It is now being reported that Efron's issue not alcohol as speculated, but lots of cocaine and some Molly. Not to make light of anyone's issues, but we here at HIGH TIMES find it difficult to fathom how a person can develop a catastrophic coke problem while chillin' with super-stoner Rogen.

Efron, dude, do yourself a favor and stick with flowers from now on.
