Roger Bates studies it:
How Bates would solve the problem:
What the U.S. government should be pushing for, but isn’t, is better international public health law against fake drugs. There are treaties against fake currency and against narcotics, but not against fake drugs. This should change. A treaty against fake drugs would help countries currently awash in fake drugs to create laws based on public health considerations and not intellectual property rights. … If we want safer supply chains, and fewer Avastin-type problems, we will have to help other countries improve their domestic public health laws.
