Charlie Sheen says the media outlet that's reporting he had Zac Efron over for drug-fueled parties is totally making it up.
Sheen tells TMZ ... he hasn't even seen Zac for nearly a year ... specifically when Efron showed up to the set of "Anger Management" 11 months ago. Charlie says he showed up not to see him ... Zac was there because they share the same publicist who happened to be on the set.
The report claims Zac visited the set at least a dozen times. Charlie says it's all made up ... Zac was there that one time only.
As for the claim Zac spent a lot of time partying at Charlie's house and then strongly insinuating they were on cocaine binges ... Charlie says, "ridiculous." Sheen says Zac was at his home a grand total of one time -- nearly 2 years ago for a Super Bowl party. The next time Charlie saw Zac was when he visited the set 11 months ago.
Charlie is also angry the report claims he's on an uncontrollable cocaine binge. He says, "Consider the fact that I have completed 54 episodes of 'Anger Management' in a little more than a year ... something that would ordinarily take more than 3 years to accomplish."
Charlie calls the news outlet "adrift and unsalvageable."
