Since 1996 the annual amount of Ritalin type drugs approved for production by the DEA multiplied 4000 times to 50 million kilograms, and for Adderall 10000 times to 26 million kilograms. In more common terms, 83,776 tons of legal speed were approved for production in 2010 equaling more than half a pound for every man, woman and child in America.
The U.S. is a signatory to a 1972 United Nations treaty monitoring the production and sale of potentially addicting substances. The U.N.’s International Narcotics Control Board (INCB) based in Vienna, monitors the production of legal stimulants worldwide. INCB data shows that in 2009 the U.S., representing 4 percent of the world’s population, produced 88 percent of the world’s legal Ritalin type drugs. Canada uses a third per capita of prescription stimulants compared to the U.S. — Germany, one eighth, the U.K. one twelfth, Japan, one fiftieth.
