Who should be the Obama administration's Drug Czar?

With the announcement that Tom Daschle has been selected as the Obama administration’s Secretary of Health and Human Services speculation about the down market appointments has accelerated. For this audience, of course, everyone is nattering on about the next Director of the NIH. My nattering sources are moving in the direction of Elizabeth Nabel, M.D. current Director of NHLBI, but that’s just vague speculation.
One of my correspondents reminded me of a non-HHS appointment that is VERY important for NIDA funded scientists and indeed everyone interested in drug abuse issues.
Who will be the next Drug Czar?
