I found this article pretty hard to read from the distracting animations, but I do like where the research is going on ketamine. Specifically, it's been found to be a good treatment for anhedonia[1], the loss of pleasure or interest in things you used to enjoy. Anhedonia makes life feel pretty empty, and it tends to improve very slowly even with treatment. Frustratingly for the animators of this article, the view that ketamine is a club drug that can also fix depression is probably not going to do wonders for its legitimacy as a serious treatment.

Tested patients with bipolar depression also on a mood stabilizer, so there's lots more research to do.
