How much heroin would it take to overdose and make it look like an accident?
Within limits, it’s not so much the amount that makes it look like an accident as it is the circumstances of the crime scene. It has to look like the individual took the heroin voluntarily, and that he he did not expect to die. The amount is important, of course, but it needs to look like the victim didn’t expect an overdose. Typical scenarios are that he mixed it with another drug like alcohol and the two were too much, or that he was used to something that was cut more but got a purer quality than usual. Naturally, if someone had five grams of heroine in him, it probably wouldn’t look like an accident. If the dose was an obvious overdose, it would look like suicide or murder. The amount that a person could tolerate would depend on whether he was experienced or a habitual user. As for how many milligrams that would be, according to http://www.drug-overdose.com/heroin.htm , it would take 200-500mg of heroin to overdos
