I know what you mean, but it really bothers me that you are only counting American deaths. The total number of Iraqi deaths arising from the Iraq war is highly disputed, but it seems to be somewhere between 150,000 and a bit over 1,000,000, depending on the survey and whether it only counts direct deaths of combatants vs. surveys that count civilian deaths and indirect effects. In any case, deaths arising from opioids are nowhere near any amount of "Iraq wars per year".
