In light of the accumulating anecdotal reports of the successful cancer treatments with cannabis extracts, the Company will continue to keep patients updated on current peer-reviewed scientific literature supporting the historical and modern use of cannabis to treat "tumors”. Unlike conventional treatment, cannabis medicines have an outstanding safety profile allowing patients in states with medical marijuana laws to safely make informed decisions to legally self-administration of various cannabis-based preparations.

The first Cannabis Science Brand extract-based formulation is comprised of high quality oil packaged in oral dispensing syringes for patient self-administration for treatment. This is a critical milestone for the Company in bringing its first formulation to market. Other formulations will be made available soon to medical marijuana patients in Colorado through the Company’s vetted dispensaries. The Company’s intent is to work with specially appointed legal providers and laboratories to expand the availability of its formulations across the United States where legally available.

Cannabis Science, Inc. is at the forefront of pharmaceutical grade medical marijuana research and development. The first formulations will address the needs of patients choosing to use concentrated cannabis extracts to treat their ailments. Eventually, all Americans will have access to a safe and effective FDA approved medicine regardless of which state they live in. To maintain that marijuana is a dangerous, addictive drug with no medical value is scientifically absurd. Cannabis medicines, with no effective lethal dose, are far safer than aspirin, acetaminophen, and most other OTC drugs that kill thousands of Americans every year.

The Company works with world authorities on phytocannabinoid science targeting critical illnesses, and adheres to scientific methodologies to develop, produce and commercialize phytocannabinoid-based pharmaceutical products. In sum, we are dedicated to the creation of cannabis-based medicines, both with and without psychoactive properties, to treat disease and the symptoms of disease, as well as for general health maintenance.
