COLORADO SPRINGS, Colo. - Cannabis Science, Inc. (OTCBB:CBIS - News), a pioneering U.S. biotech company developing pharmaceutical cannabis products, is pleased to announce that it is adding Online Communication Specialists in response to an increasing interest in Dr. Robert Melamede's understanding of the amazing roles played by the endocannabinoid system. Dr. Robert Melamede, PhD, Cannabis Science President and CEO has been accepting numerous invitations to speak about Cannabis Science at a wide variety of medical marijuana events around the world, including in the U.S., Australia and Canada, regarding his concepts of the unique role played by the endocannabinoid system in life and health.

The company is excited to launch a higher quality Internet Presence through the new Specialists who will be focusing on the Company website content, the website communication interactions, and social media networking sites. This was brought on after receiving such a high level of media interest from Dr. Melamede's public speaking engagements, and news interviews, the Company has been focusing on expanding its online communication outlets and corporate sponsorships. As well, the Internet specialists will be focusing on bringing investors, scientists and the general public to the Company website, plus its blogs, newsletters, and forums.

Included in his talks is his hypothesis "that endocannabinoid deficient people (backward-looking people, "BLPs") naturally concentrate in government, and this explains why cannabis prohibition exists in spite of the plant's anti-aging and anti-cancer properties". He furthermore states, "I am confident that cannabis science and the will of the people will continue to fuel the ever increasing demand for effective and safe cannabis-based medicines."

The Company is excited to provide these resources in conjunction with the previously announced educational series that will be presented on national television and the company's website shortly. Dr. Robert Melamede's worldwide media tour and the continued development of online resources will provide Cannabis Science with the ability to keep its Patients, Investors, Doctors, and Partners continually informed on new developments and upcoming events.
