Who designed the standard for harm in this instance? How is the self-inflicted harm of addiction that is the actual foundation of the secondary harm caused, for example, by dirty needles and overdose weighed? Is the harm dealt to one’s family considered? “Helping them stay on drugs” is the practical way of looking at it, because in practice that’s what’s happening. “Reducing harm” in this context sounds like some sort of neo-Hippocratic Orwellian spin on the fact that the alternative is to address the greater issues that lead to and foster drug addiction that are beyond the scope of this tiny box that I’m typing into and do not involve more needles.
