This is a hugely important topic and many whistleblowers have already come forward with shocking exposures of the industry's criminal behaviour - including regularly paying for drugs and prostitutes for some doctors the US to bribe them to prescribe their drugs.
I really suggest reading through these 2 posts from my whistleblower series if you haven't already:

Also - on a tangent - I'm reaching out to all my followers who have significant Steem Power to ask them to consider voting for me as a Steem witness - as I need the votes to boost me up the ranks and that helps pay my costs and funds exciting projects I have planned to help grow Steemit.
[My witness application is here](https://steemit.com/witness-category/@ura-soul/ura-soul-witness-application). Cheers!
