You need to consider your informational sphere, considering you are on HN its probably vastly different than 95% of the US. Most of the US still views drug use as a criminal issue, including psychedelics. Psychedelics are still central to large pieces of the counter culture.
I live and operate well outside of the typical sphere of Hacker News. Cannabis has been normalized across my country for decades. It's well known for it.
MDMA and LSD are marginalized? Everyone I've ever known has either tried them or knows someone who has. Psilocybin even more so. That was practically a rite of passage growing up in rural Canada.
