I'm still surprised how marijuana posts are so frequently pushed in HN. My take is that the effect is negative, I've seen just a ton more brazen usage out in public once this thing hit with a bunch of phony Dr prescriptions given to perfectly healthy people. It's all a ruse in my book, you're either growing in virtue or backsliding. At best drug use is suboptimal for a thriving philo-generative culture to borrow Daniel Hannan's phrase.
