Much of the legislative activity has stemmed from Purdue Pharma’s decision in 2011 to begin a modification of Oxycontin’s composition to make it more difficult to crush for snorting or injecting. The new formulation, OxyNeo, is intended to be preventative in this regard and retain its effectiveness as a painkiller. Since introducing its Narcotics Safety and Awareness Act , Ontario has committed to focusing on drug addiction, particularly in the monitoring and identification of problem opioid prescriptions, as well as the education of patients, doctors, and pharmacists.  This Act, introduced in 2010, commits to the establishment of a unified database to fulfil this intention.  Both the public and medical community have received the legislation positively, though concerns about the ramifications of legal changes have been expressed. Because laws are largely provincially regulated, many speculate a national strategy is needed to prevent smuggling across provincial borders from jurisdictions with looser restrictions. 
Richard, your statement brings up another weakness found in observational studies: there is a confluence of factors that could play a role in health and longevity. You say that “as Okinawans move away from Japanese yams, vegetables and fruits to more meat and processed foods that disease is increasing.” How do you know the determining factor is grass-fed organ meat when you yourself said that another factor was processed foods. Are they equal? Indeed, Okinawans have not only increased their intake of conventionally raised meat (., unhealthy product–unlike grass-fed meat and pastured eggs) and processed foods, but have also increased their intake of whole grains. Their lifestyles have also become more sedentary. More Okinawans smoke tobacco and drink alcohol than did in the 1950’s.
