True. He's in government, and specifically that government, so he has access to all the money and drugs he wants, so if he's remaining clean, he's doing exceptionally well on that score.

This should not be taken as an endorsement of his abilities as a politician or his knowledge about science. Plenty of other evidence suggests he should be doing neither of those. Hell, I'm not even sure I'd follow his advice if I was a heroin addict trying to get off the stuff.
