Even if you are drug-free now, you could have a procedure in couple years and become addicted to opioids during recovery. Many people who are suffering from the opioid epidemic were prescribed these drugs.
Life expectancy if you get the surgery and medicate with pot: 80 years.
Life expectancy if you get the surgery and use the opioids: 60 years.
That seems immeasurably more useful than a national average alone which only can be used for political talking points.
So you won't find them for all the options of interest, and you emphatically won't find them for emerging options (including pot, which hasn't been even quasi-legal long enough to support good data.)
