You say that heroin has an effective dose to lethal dose ratio of five, however I have read in many sources that such a calculation for opioids (which includes opium, morphine, heroin, and perscription painkillers) has never been done conclusively, and that addicts routinely survive 10 times their usual dose without even falling asleep. What is your source for this ratio of 5-10?
