It's no-one's fault, but it's the individuals fault? Don't they contradict each other? Sorry mate, but you've fallen for the propaganda that anyone who sells addictive or harmful shit puts out. It's never their fault for selling it and deliberately targeting vulnerable people. It's the addict's fault, even though we know quite a lot about how the brain of an addict works and how they struggle to have the same individual choice as a non-addict. Just keep blaming individuals and watch the problem get worse and worse. Or accept there's a systemic problem and actually do something about it. Those are the options.
