Cannabis Science (CBIS) Moves Forward with Critical Support of Landmark Federal Cannabis Legislative Initiative

(NASDAQ OTC: CBIS) Cannabis Science, Inc., a U.S. Company specializing in cannabis formulation-based drug development, is a key leader in the private sector challenge to end the restrictions on cannabis drug development and research in the U.S. "The Cannabinoid Scientific Research and Development Act," which will be submitted for congressional review in the U.S. Senate and House of Representatives by the end of January 2014, is landmark legislation seeking equal treatment for cannabinoid scientific research. In addition, the legislation aims to provide the framework for the clinical investigation of the hundreds of strains of cannabis and their constituent cannabinoids regarding their medical efficacy on a wide range of life-threatening, chronic, and infectious diseases.

The legislation also seeks to provide "an informed clinical environment for physicians, researchers and consumers to make effective clinical choices regarding their therapeutic treatments for a variety of diseases," said Dr. Robert Melamede, President, Cannabis Science. "We need rational federal standards based upon science to replace inadequate public policies rooted in the misperceptions of the past," Dr. Melamede added.

The legislation directs the U.S. Secretary of Health and Human Services to develop guidelines, standards, and regulations that provide the framework for development of cannabis research. It also asks that this new regulatory framework begin rapidly after the removal of legal and regulatory obstacles for that research and that these guidelines follow a milestone 2007 Drug Enforcement Administrative Law ruling overturning the prejudicial procedures that effectively disallow domestic cannabis research and drug development.

Cannabis Science views these federal legislative developments as a critical part of the growth and development of its domestic biotechnology business. "We need the same consideration in terms of the ability to conduct clinical trials and to develop therapies as other firms in the biotechnology sector," said Dr. Dorothy Bray, CEO of Cannabis Science. Dr. Bray continued, "We also need to level the playing field to match rapidly changing regulatory environment in other countries that either have or are accommodating cannabis research."
