harm reduction vs abstinance

this paper is on 2 approaches regarding the opiate crisis in the united states. The focus is only on opiates. We need to explore harm reduction vs abstinence. We will use methadone and vivatrol and narcan for the harm reduction and for abstinence we will be using Narcotics anonymous and detox/IOP approaches. WE will talk about the pros and cons of each approach, as well as success rates pertaining to both approaches. We will also analyze what is the magnitude of the opioid crisis currently and the system of care options.  I will need the affected demographics mentioned as well as why they are now considering this to be a crisis
We will also find research showing what had been more effective based on these 2 approaches.ie: relapse rate short term and long term recovery outcomes etc  and when each approach was introduced
lastly  you will look to see if further research on this topic is needed and if you believe there should be more funding for research based on this. as well as your(my) recommendation as to which approach I would focus more on in this funding. I will let you know that my belief is the  complete abstinence  approach

I will be uploading some articles I found on this subject in the near future
