Project CBD was established in 2010 by journalists who had been covering the medical marijuana story — the science, the movement and the industry. We felt that the reintroduction of CBD-rich cannabis into the grassroots supply merited special attention. The serendipitous reappearance of whole plant CBD in Northern California in 2009 has given doctors and patients a unique opportunity to evaluate the effects of cannabidiol. Project CBD updates doctors and patients on developments in cannabis science, therapeutics and political economy.
