I would like to thank Nora Volkow, who helped ‘brainstorm’ this collaborative
process and who delivered the symposium’s keynote address, and our distinguished
NIDA colleagues Yonette Thomas and Wilson Compton for their sustained support
and friendship, as well as the many colleagues and contributors from the worlds of
geography and medical sciences who made the symposium and this book possible.
