CURES works but at the cost of completely negating any type of privacy protection on medical records. Pretty much anyone (prescriber, dispenser, law enforcement) can pull up CURES reports knowing a persons last name and birthdate.
What is the point of HIPAA and medical privacy if anyone can log in and see what scheduled drugs you're taking? From the drugs you take I can pretty much derive your medical history. I consider this a much larger problem than the 'war on drugs'.
