So, it's less about the substance and more about the person. Does the substance have addictive properties, yes, but not everyone becomes addicted. For instance, someone can eat a fattening, sugar-filled meal once and be okay. They'll go back to eating healthy. No harm, no foul. Someone with a predisposition for addiction can eat that same meal and start to exhibit addiction through disordered eating. This country is long overdue to reevaluate the way we look at and treat addiction. We focus way too much on and get way too hypocritical about specific substances.
