The Rockefellers and their pharmaceutical empire
With the AMA and allopathic medical schools firmly in place, the abolition of other medicinal therapies, and the enforcement of regulated licensing of doctors, the Rockefeller empire continued to expand. Sterling Drug Inc., the largest holding company in the Rockefeller drug empire and its 68 subsidiaries were maintained under an umbrella with the Rockefeller-owned bank Chase Manhattan (now known as JP Morgan Chase Bank) and called the Drug Trust.
We cannot forget that the pharmaceutical empire of the Rockefellers includes vaccines, sedatives, analgesics, antibiotics, heart drugs, and hypnotics.
Under the directive of the Rockefeller Foundation, funds to medical colleges in 1948 alone swelled to $32 million, which in today’s money would amount to $323 million. This ensured that the medical schools would teach and indoctrinate the names and uses of thousands of drugs.
In the 1930’s John D. Rockefeller, Jr. campaigned for the prohibition of hemp and cannabis through generous political and Baptist church donations. Hemp could produce ethanol, which competed with petroleum, and cannabis was a competitor with opium and with the Rockefeller-owned member of an opium cartel: Bayer, creators of heroin.
