Cannabis Science President and CEO Dr. Robert Melamede, PhD., Files Preliminary Patent Disclosures With the University of Colorado Regarding New Technology That Cannabis Science Intends to Develop Through a Private Company Acquisition

COLORADO SPRINGS, Colo. - Cannabis Science, Inc. (OTCBB:CBIS - News), a pioneering US biotech company developing pharmaceutical cannabis products, is pleased to announces preliminary patent disclosures and major steps towards the acquisition of a private company for the development of the new patentable products that should facilitate broad acceptance of specific Cannabis Science pharmaceutical products designed for the treatment of chronic pain, Post Traumatic Stress Disorder (PTSD) and other critical illnesses addressed throughout the www.cannabisscience.com company website.

Dr. Robert Melamede, PhD., Cannabis Science President and CEO, reported, "We have been negotiating to purchase a privately held biopharmaceutical company that owns complementary patented intellectual property for specific clinical stage cannabinoid products and uses. As a faculty member at the University of Colorado at Colorado Springs, I have filed a preliminary patent disclosure with the University of Colorado regarding additional new technology that Cannabis Science intends to develop through the targeted private company acquisition. As a part of this process, we are hiring a distinguished patent attorney to help with the University disclosure and ultimate patent filings. We are also using our FDA consultants to advise on the technology's FDA approval pathway because we foresee several new FDA pharmaceutical products that can be derived from this deal."

Richard Cowan, Cannabis Science CFO, explained further steps the company is taking, "We are hiring a prominent Los Angeles law firm to perform the due diligence on the acquisition to confirm representations and formalize the structure of the deal. Negotiations on the over-arching technology related to the above disclosure have been ongoing for the last few months and we have now reached the point where we are prepared to move forward. The attorneys will validate the development of the proprietary intellectual property by previous licensees of the technology. They will also examine several patents already filed and or issued on the related technology. This development is further evidence of Dr. Melamede's ability to identify and bring together a variety of new technologies aimed at developing pharmaceutical cannabis products that target critical illness for worldwide distribution."

Dr. Melamede emphasized, "Yesterday was Memorial Day when we are supposed to remember those who have fought for our country, but we are still way too far behind when it comes to helping our veterans suffering with PTSD, chronic pain, and other problems for which many have found that only medical cannabis can help. We remain committed to the development of various pharmaceutical cannabis products for the treatment of Post Traumatic Stress Disorder (PTSD) and related pain among our veterans to whom we owe so much. The intellectual properties mentioned above should specifically facilitate getting Cannabis Science's products to military personnel in need of our Cannabis Pharmaceutical medicines."
