Yes - but only in clinical drug trials, in order to test whether a drug having an effect is only due to the placebo effect (people thinking they're taking a drug and so getting better because of "mind over matter", basically), or if it's having an actual, measurable effect beyond the "placebo effect". Taking a placebo and marketing it as an actual drug is illegal, I'm pretty sure, not to mention immoral.
