Is Reddit the new Erowid? is described as “a member-supported organization providing access to reliable, non-judgmental information about psychoactive plants, chemicals, and related issues.” The site was launched in 1995 and by 2005 had 450,000 page hits and 45,000 visitors per day. Website use statistics haven’t been reported since then, though its likely that there has been some attrition due to the growing diversity of online resources for drug information.  Out of curiosity, I ran a quick Google Trends search to compare where Internet users are searching for information about two well-known synthetic drugs, LSD (acid) and MDMA (ecstasy).  The following chart depicts searches for these two keywords that were accompanied by either “erowid” or “reddit”, as well as a search for “erowid reddit”.

Monthly search data were obtained from January 2004 through the present day and trendlines were smoothed using a logarithmic ^4 transformation. What we see is that sometime in 2015, searches for information about these drugs related to Reddit appeared to overtake searches related to Erowid.  Implications of this trend go beyond simple navel-gazing about Internet search preferences.  For example, if individuals are now more likely to get information about psychoactive drugs from Reddit, it begs questions about the quality of information that they are getting (particularly information about risks and interactions which is prominent and well-curated on the Erowid site).


FitBit sleep tracking

Relative per-capita endorsement of the 2012 Open Access petition in the U.S.

This is an interactive chart – hover over states to display their scores! If the chart doesn’t display, the static image is here.

Data include individuals who self-reported a location in one of the 50 U.S. states for the first 25,000 endorsements (n = 15,695) on the official White House petition site. Per-capita figures were calculated using 2011 Population Estimates, standardized, and scaled to a mean of 50 and standard deviation of 10 for comparison purposes. The chart was created in Google Charts and the raw data are available here. Continue reading
