First heard about Erowid in this recent New Yorker article: http://www.newyorker.com/magazine/2015/11/23/the-trip-planners http://www.newyorker.com/magazine/2015/11/23/the-trip-planne... I found this article and the testimonials from the website itself a bit more interesting than the visualizations here. The New Yorker article describes Erowid's role as a reference source for the medical and research community. I get the impression from the writeup here that this project, associated with the University of Amsterdam, scraped Erowid to collect the data. I hope, as researchers, they'll make the data open for others to explore and extend.
