Britney's Drug Report (DuH)

Reports are circulating that Britney's positive drug test last week was the result of Provigil, a prescription for treatment of narcolepsy. (YA RIGHT)

In generic drug testing -- the type performed on Brit Brit -- there is not a special screening for Provigil.

In addition, we know the tests actually performed on Spears (until last week) all came back negative, and she had been taking Provigil before that.

Of course, we all know she also regularly tests positive for the generic version of Novartis AG's genital herpes drug Famvir.
