Well, as I've said before, I'm not so sure you understand much about the nature of addiction (in particular the biology of addiction. Both my experience and the empirical research done on substance use disorder suggests that addiction is FAR more than about drug use.
The opporiste of addiction is connection, not abstinence. Abstinence is a strategy that may benefit or may not benefit those seeking help overcoming the challenges of addiction treatment. And, for your information, humans are not simply hard wired to love heroin. If that were true once an addiction always an addiction. However, again the research suggests that this simply isn't the case. If it were, I wouldn't have been able to successfully move on in my life from heroin use.
You post above is a perfect example of how addiction as a brain disease promotes by the likes of the NIDA is not a very efficacious, and can end up easily promoting stigma associated with substance use disorder. And the stigma surrounding addiction and the related isolation and alienation is impossible ofor address my simply focusing on dru g use. The effective treatment of substance use disorder requires the effective integration of users with therapeutic, supportive community,
To try and argue that humans simply seek dopamine and that addiction is more about nature (biology) than nurture. Certainly nature is involved in dealing with this stuff, but nurture plays an even greater role (addiction is more accurately termed a learning or developmental disorder, not a brain disease).
I take it you don't know about the Rat Park experiments? That research very effectively demonstrates that even though even when access to unlimited pharmaceutical grade substances, social animals (such as rats and humans) the subjects greatly prefer spending time playing, mating and otherwise living their little rat lives. And when it comes to humans, The nueroscience research of the like the Carl Hart has demonstrated that, presented with very small incentives, like a $20 gift card for the market instead of a dose of pure cocaine or methamphetamine.
I strongly suggest you learn more about the history of addiction and how society has dealt with it. The SL directory has a link to a great comic by a Stuart McMillen explaining the finding of Rat Park. Basically they found that rats would only use drugs when there were isolated from one another. If addiction were merely a brain disease, this wouldn't be the case. If anything, as social animals ourselves, human beings tend to rely far more on substance use to regulate their mood than when they aren't connected much with other people.
And the scientific aside, I find the kind of attitude about addiction you're presenting as far too deterministic. The fact of the matter of something even like heroin use is that the vast majority of people will either simply age out or harmful patterns of drug use during their later twenties and thirties or, with a change in environment geared towards supportive recovery communities, the circumstances of our lives has more to do with heroin use than anything inherent adopt about the pharmacological properties of heroin. None of this would be possible if addiction was more about our nature and bilogy than nurture and environment.
