Erowid Announcement #10
November 15, 1999
Hey Entheophiles,
To start off this announcement an interesting development last week the U.S. patent office has suspended the patent on Ayahuasca (Banisteriopsis caapi) after formal complaints were filed by several organizations representing indigenous people of the Amazon basin. The decision can still be appealed by the patent holder, but now he has to prove his case before the patent can be re-instated. Generally considered a very good decision, if somewhat late in coming.

We welcome submissions, suggestions, criticisms, or corrections at



  1. Hyperreal Drug Archive Historical Snapshot

    The Hyperreal Drug Archives have closed and we've happily agreed to host a full historical snapshot of the site as well as incorporating nearly all of the files into the vaults. All old HDA urls will now automatically forward you to the file's new location at Erowid. There are over 450 new files, far too many to list them all here, but a list can be found on the what's new page ( added primarily between Oct 11 and Oct 19.
