They are almost identical. Let’s try another two, MDMA and heroin:

Again they are very similar, but with a slight tailing off for MDMA (harder to make in the UK since 2008).

Now let’s try mephedrone and cocaine. The difference is massive.

Meanwhile, it is almost completely absent from the medical literature.

The Pubmed version had broken due to a change in the Pubmed results format. It was easy to fix and now you can query for all kinds of trends in the biomedical research literature. See the previous blog post for more examples.

I also removed the “powered by Yahoo” icon because Yahoo are not serving it any more. It seems we’re using a deprecated API now, but I guess it will work for a while to come.

And while we are here, I’ll post a graph for old times’ sake:

Happy comparing!

A long, long time ago when Compare Stuff was young I made a version which made it easy to do quantitative biomedical literature search analysis. I have now blown away the cobwebs, improved it a little (now you can compare 8 things) and will briefly demonstrate its genius…
