This made more sense as I read what neuroscience can now tell us: that every human brain has capacity for addiction. Isolation is part of why some people get addicted and some do not. So was trauma. Abuse, rape, neglect, PTSD, a parent’s drug use were as unspoken in America as addiction and as prevalent. The epidemic was revealing this. I also connected the epidemic to consumer marketing of legal addictive stuffs: sugar, video games, social media, gambling.
