I'm a little disappointed that the author didn't investigate prescription drug sales. Google 'XanaxKing' if you'd like to understand something about how lucrative this trade is, and how popular it is on the deep web. These are professional operations moving significant quantities, so we're missing a major part of the market.

I would also have liked to see some indication of how the data was cleaned or some quality control measures, but understand that this was a quick experiment. More interesting data should surely follow in the second post that analyzes changes over time.
