I think your conclusion is correct, but not a problem, precisely because concepts like 'addiction', as well as 'mental disorder' are contextually defined. ADHD might not be a problem if you're living in a wild environment and roaming the woods as a primary activity. Schizophrenia might not be an issue of you live in a society where you're considered a 'seer/prophet' and taken care of by the community for your 'valuable' service. Heroin might not be an issue if you're filthy rich and happy with your lifestyle. Practically speaking, of course society might value labeling any use of heroin as 'addiction' because it might be too rare for people to be able to live well while using. Similarly, I believe making alcohol a bit more of a 'drug' (as it is commonly seen) is not a bad thing because so many people, relatively, become unhealthily dependent on it. I've become more and more convinced that it would benefit us all if we 1) let go of our somewhat arbitrary current definitions of 'illegal drugs' and 'addiction' (at least in 'common' conversation), and 2) keep in mind that the goal of criminalizing a substance or labeling someone as 'mentally ill' is to help people function in whatever society their in, and not an attempt to objectively define any of these things. I have a lot of friends who by many definitions suffer from various 'mental problems'. Many of them function well because they chose a lifestyle, career, and social environment that suits them, rather than taking the path of medication. While this is not an option for everyone, I wish the mental health industry would spend more energy on this rather than simply 're-socializing' people through medication or therapy. To be clear, I realize this is not a simple issue, and that for many people medication is a lifesaver. I also realize that the impact of incorrectly advising people on these matters can ruin lives. I'm not an expert!)
