An fyi: Steve Simske of Hewlett-Packard offers a nice, unbiased (though HP-oriented) perspective on current anticounterfeiting measures from his Security Printing and Imaging blog. Definitely worth a view. Today he reminds us of the potential benefits of using stable isotopes as a way of authenticating processes by which APIs and drugs are made.

It's a topic we've covered quite a bit, with some help from John Jasper of Molecular Isotope Technologies, who's worked with FDA, J&J and others to advance the technology:
