This is one reason why Dr. Vincent Felitti—one of the key figures in the Adverse Childhood Experiences Survey—concluded, as Gabor writes, that “the basic cause of addiction is predominantly experience-dependent during childhood, and not substance-dependent. The current conception of addiction is ill-founded.” This fact forces us to radically reconsider many of the stories we are told about drug epidemics—including, I was to learn later, the prescription drug epidemic in the United States.
