Last week we told you about Samir Chachoua, the doctor who dangerously appeared on Bill Maher's show claiming that he "cured" Charlie Sheen of HIV by using an alternative therapy derived from goat’s milk.

Well now, Sheen is calling the doctor out on Twitter, implying he is not being honest.

"Dr Sam I was with u in Mexico for 1 day. It's illegal for u to practice in U.S.A. where u treated me for 2 months," he tweeted, with a photo of Pinocchio's growing nose attached.

Sheen reportedly had to return to his conventional therapies and treatments last month when he quickly realized the goat's milk therapy wasn't working.

Chachoua saw Sheen's comments on Twitter, and responded with disappointment.

AIDS activists are worried about the dangers of Chachoua's claims, saying, "I know for sure that some folks will end up dead because of all this."
