Post-industrial capitalism has completely destroyed the conditions required for healthy childhood development.
if you look at the brain circuits involved in addiction—and that’s true whether it’s a shopping addiction like mine or an addiction to opiates like the heroin addict—we’re looking for endorphins in our brains. Endorphins are the brain’s feel good, reward, pleasure and pain relief chemicals. They also happen to be the love chemicals that connect us to the universe and to one another.Read the whole thing.
Now, that circuitry in addicts doesn’t function very well, as the circuitry of incentive and motivation, which involves the chemical dopamine, also doesn’t function very well. Stimulant drugs like cocaine and crystal meth, nicotine and caffeine, all elevate dopamine levels in the brain, as does sexual acting out, as does extreme sports, as does workaholism and so on.
Now, the issue is, why do these circuits not work so well in some people, because the drugs in themselves are not surprisingly addictive. And what I mean by that is, is that most people who try most drugs never become addicted to them. And so, there has to be susceptibility there. And the susceptible people are the ones with these impaired brain circuits, and the impairment is caused by early adversity, rather than by genetics.
