migraine, a diagnosis which remains extremely problematic today, and whose
pathophysiology seems intimately related to a disturbance of the endocannabinoid
system (Russo 2001 ; Russo 2004 ; Sarchielli et al. 2007 ; Akerman et al. 2007 ;
Akerman et al. 2003 ; Akerman et al. 2004 ; Russo2016b).
2.7 Conclusion: Contemporary Cannabis Research
in Ireland
The research pioneered by Irish physicians in the 19th century paved a path that
after a long hiatus is now being pursued afresh by modern researchers. A story in
theIrish Timesin 2015 has outlined these new investigative initiatives (King 2015 ).
Researchers such as David Finn, Eric Downer, Veronica Campbell, Michelle and
Roche, Saoirse O’Sullivan and others are carrying on a proud Irish tradition of
enquiry that holds great promise for therapeutic advances with cannabis. It is hoped
that the lessons of the past will help to guide their investigations toward future
benefits in the treatment of recalcitrant maladies.
Acknowledgements I would like to thank Dr. Davis Coakley for his excellent scholarship on
Irish medical history, as well as his provision of materials on Michael Donovan, and the
hard-working staff of Inter-Library Loan, Mansfield Library, University of Montana for their
assistance in providing rare and long-forgotten documents.
