I'm trying to find some citation but I really can't - all I know is that I've heard her speak before and been impressed by her immense vocabulary. Similarly, this speech reinforces that former impression.

And what's up with drug use discrediting her intelligence? That's just stupid.

I agree. Hunter S Thompson was quite the druggie and managed ok.
