I thought most overdoses are the result of variable potency which is the result of the prohibition. Are you saying that accidental overdose would be a significant danger for addicts if they had a reliable supply of predictable potency? If that is what you're saying, do you have any evidence to support that?

I do agree that easy access to powerful opiates is a recipe for disaster for people at risk for suicide. And I concede that the danger of a negative feedback loop is obvious.
