frugaldoctor, I agree 100% , I had an impacted wisdom tooth removed and took only Tylenol. I think I was given a rx for Vicodin , I never filled it. I am not a fan of pain I just known what can happen with those pills(even after 3 or 4 days). I had a semi major surgery when I was a teen and was in the hospital for a week and they gave me Demerol injections before sleep every night. on the last night the nurse said doctor left it open to me(along the lines of not recommended but allowed) I felt the urge to say yes and felt a rush just thinking about it. that scared me and I said no! I could have said yes and wanted to. I am not mentally stronger or more disciplined than other people I just thought it threw a little more and recognized I did not like my reaction to having the option and that was after just 6 days of taking it.
Regarding incidence and prevalence, of course both matter. But the point was that treatment does not reduce incidence. Technically speaking, treatment does not reduce prevalence either if you consider addiction to be a chronic condition.
Where’s the sad button. 
I had an extensive surgery this year and the only thing I feared was home opioids. I took 2 percocet pills after surgery and threw the others away. My discomfort was better than the risk of addiction.
Does anyone know if police in Ohio (and other hot spots) are routinely carrying Narcan? My BIL is an EMT in the Chicago area and they keep Narcan… I assume many (most? hopefully all!) EMTs are equipped with it but I’m not sure about the police.
ETA: Maybe found an answer? http://kwqc.com/2016/09/19/cost-of-opioid-reversal-drug-adding-up-for-ohio-law-enforcement/
State Troopers here and a lot (not sure how many) of the local police departments–yes, they are carrying it. Most of which I am aware started within the last 3-6 months.
I just read yesterday that our State Dept. of Health has 50 (that didn’t seem like a lot) of extra doses for emergency supplies to give out to police departments when they run short, at a cost of $100,000 to the taxpayers.
