Right. I get that and agree. The article is about the effective way to actually help with heroin addiction. The comment I replied to said, "An addiction tries to replace a void in someone's life. Chances are big the environment of the addicted played a role in cerating[sic] the void."
"Chances are" he's identified a vague cause? I'm not saying he's wrong, but that it doesn't help an addict to point that out. And again, the article is all about effectively helping the addict.
I don't think we disagree except for in the intent of my original comment.
