"A presidential candidate admitting to marijuana use is nothing new. That happened in 2004, 2008, and 2016."

"But I've never seen any presidential candidate other than Kamala Harris follow up that admission with this kind of argument for legalizing marijuana: 'I think that it gives a lot of people joy, and we need more joy.'"

Writes my son John, on his blog, linking to "Kamala Harris says she smoked marijuana in college, calls for legalization" (ABC News).

This reminds me of why I changed my mind about legalization in March 2015 as a result of reading something written by Paul Johnson about Henrik Ibsen:

There was one aspect of Ibsen’s vanity which verged on the ludicrous... He had a lifelong passion for medals and orders. In fact, he went to embarrassing lengths to get them...

[T]here is ample evidence for Ibsen’s passion since he insisted on displaying his growing galaxy of stars on every possible occasion. As early as 1878 he is reported to have worn all of them, including one like a dog-collar round his neck, at a club dinner. The Swedish painter Georg Pauli came across Ibsen sporting his medals (not the ribbons alone but the actual stars) in a Rome street. At times he seems to have put them on virtually every evening. He defended his practice by saying that, in the presence of ‘younger friends’, it ‘reminds me that I need to keep within certain limits.’ All the same, people who had invited him to dinner were always relieved when he arrived without them, as they attracted smiles and even open laughter as the wine circulated....

That's about alcohol, but it jogged my thinking. As I elaborated later:

I'm not a big marijuana legalization advocate, though I did change my position on the subject fairly recently, because I think substance-boosted disinhibition is important, though overdone.

When people didn't understand the connection to the passage about Ibsen, I said,

Here's a clue: freedom and democracy depend on our disinhibition; we need to be able to laugh at authority. 

Without the disinhibiting substance, Ibsen would have got away with his stupid pomposity.

I'm talking about something a bit different from "joy." I like joy too, but there's something with more edge that I'm interested in.

And speaking of edge, here's something else I found searching my blog archive for Ibsen and marijuana. From April 2016, "The perfect problem — when everything big and small and up-to-date and retrospective and cool and puritanical collides in one crowded intersection":

"Snapchat's new Bob Marley lens sparks 'blackface' outrage."

To acknowledge 4/20, known as "Weed Day," Snapchat created a special "lens" that morphed people's faces into Bob Marley, the late reggae icon. The lens added dreadlocks, a crochet slouch cap, changed the shape of eyes and noses, and darkened skin color.

People flooded Twitter with accusations that Snapchat had created a blackface filter....

And this is why we need marijuana.

But that was April 2016, and now it's the Era of That's Not Funny! And it's been the week of hammering it into everyone's head that blackface is always always offensive and never ever funny. Ibsen didn't think his medals were funny. Kamala Harris imagines marijuana bringing joy — just some nice elevated feelings. But what if we get started laughing and we can't stop? It's a slippery slope out of the Era of That's Not Funny.
