I think you're missing the point of the article a bit. Everyone knows Heroin is dangerous and it's iterated on in the article as well. Only responsible and healthy individuals should self-use drugs, generally speaking.
Then you can also argue that you might not have lost your friends only because of Heroin the substance, but also how people with heroin addiction is "treated" and frowned upon in society.
I think what the article is trying to say is that harm reduction is a much more human and possibly effective approach to fighting real addition. Compared to other ways, which some of them include "there is no such thing as responsible drug use, it's all addiction" and treating people as such.
