SAN FRANCISCO, CA--(Marketwire - July 20, 2009) - Cannabis Science Inc. (OTCBB: CBIS), an emerging cannabis pharmaceutical company, is pleased to announce that the Company is moving forward with its preparations for a pre-IND meeting with the FDA, which will provide guidance on the manufacturing, non-clinical, and clinical development program for Cannabis Science Drugs. As well the Company reports intentions to move corporate headquarters to Colorado Springs, Colorado. Dr. Melamede is currently in discussion with facilities in the Colorado Springs area.

“It is very important to understand that our initial drug formulation is ready now, which often costs major pharmaceutical companies millions of dollars to reach this stage. Our initial pre-IND work will establish non-clinical product safety (safety pharmacology, pharmacokinetics, and toxicology) under FDA guidelines. We are also identifying and establishing appropriate GMP compliant testing and manufacturing facilities. If the assumptions we make about pre-existing information are accurate, our costs in time and money to get to the pre-IND meeting with the FDA will be much less because our initial drug formulation is ready now. We look forward to working with the FDA and to following their recommendations with the steps that are required to ultimately produce our first FDA approved pharmaceutical product,” stated, Cannabis Science Inc., President & CEO, Dr. Robert Melamede Ph.D.
