What sort of data is there about ODs? Don't people still die of medication ODs? Yes, there have been cases of people dying from lower amounts, but those instances are not reliable indicators.
A comprehensive study involving 421,466 attempts at overdose using medications found that only 21,594 resulted in death (5.1%), often in individuals with existing and underlying health issues or using multiple drugs (including street obtain drugs with other substances).
Other studies report success (for our purposes) rates ranging from
1-6%,
although one report went to 8%, which puts the comprehensive study I've chosen above at the high-mid to higher end of the spectrum.
