I wouldn't want a guest on my show who was drunk. I can't see why I would want one who was high. (Unless, of course, I was interviewing Snoop Dogg, in which case I would expect him to be on something.)

It doesn't matter whether it's legal or not. Alcohol has been OK for a very long time. But if you heard someone who had a bit too many on air, you'd likely turn it off. Then again, is it alright if they had a drink or two before coming on air? As long as they're coherent, I suppose it's fine. Maybe the same applies to a puff or two. But I would rather have someone who was sober and chose to use AFTER they were done speaking.

(As a third point, Peter Marshall in his book about hosting the original Hollywood Squares noted that the shows taped after the cast and crew had lunch were always better because the celebrities had a few belts in them and were out of it by then. So who really knows?)  

Looks like Musk is on his way to his 19th Nervous Breakdown.

Too many irons in the fire. Too much self-confidence. Too much stubbornness. Too little willingness to adhere to at least a modicum of respect for norms, no matter how quaint and dated he may think they are.

The next few weeks will be fascinating to watch.
