On January 3, 2017, Cannabis Science entered into a CRA with Dana-Farber, one of the world's leading cancer centers. Under the terms of the CRA, Cannabis Science and Dana-Farber will jointly investigate and develop use of cannabinoids to treat various forms of cancers.

"I am excited about Cannabis Science's relationship with Dana-Farber. When I first met Wilfred Ngwa, PhD, Director of Global Health Catalyst at Harvard Medical School and Principal Investigator for the CRA, we immediately realized potential synergies on cancer research interests, and the potential to collaborate to develop cannabinoid-based medicines to treat cancer and control cancer symptoms with minimal side-effects," stated Dabney.

Dabney and Ngwa met during the Constituency for Africa's (CFA) annual Ronald H. Brown African Affairs Series in Washington, DC in September 2016, where they both were on the speaking program. Mr. Dabney is a Member of the Board of Directors of CFA, and the Vice Chairman of CFA's African Healthcare Infrastructure Committee (AHIC).
