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. 
More recently, androgen receptors have been shown to have a second mode of action. As has been also found for other steroid hormone receptors such as estrogen receptors , androgen receptors can have actions that are independent of their interactions with DNA.   Androgen receptors interact with certain signal transduction proteins in the cytoplasm. Androgen binding to cytoplasmic androgen receptors can cause rapid changes in cell function independent of changes in gene transcription, such as changes in ion transport . Regulation of signal transduction pathways by cytoplasmic androgen receptors can indirectly lead to changes in gene transcription, for example, by leading to phosphorylation of other transcription factors.
