Addiction: five trashcans, four lids

"The new definition leaves no doubt that all addictions—whether to alcohol, heroin or sex, say—are fundamentally the same. Dr. Raju Haleja, former president of the Canadian Society for Addiction Medicine and the chair of the ASAM committee that crafted the new definition, told The Fix, “We are looking at addiction as one disease, as opposed to those who see them as separate diseases. Addiction is addiction. It doesn’t matter what cranks your brain in that direction, once it has changed direction, you’re vulnerable to all addiction." That the society has stamped a diagnosis of sex or gambling or food addiction as every bit as medically valid as addiction to alcohol or heroin or crystal meth may spark more controversy than its subtler but equally far-reaching assertions... When we use alcohol or drugs, Publicker says, the chemical reward—the "high"—is many times more powerful than the natural circuitry’s reward, and the neurological system adapts to the flood of neurotransmitters. “But because we didn’t evolve as a species with OxyContin or crack cocaine, that adaptive mechanism overshoots. So it becomes impossible to experience a normal sense of pleasure,” he continues. “Use of the substance then happens at the expense of what otherwise would promote survival. If you think about it from that standpoint, it begins to account for illness and premature death." — The Fix

Takeaway: confirms, broadly, the 'disease' concept but leaves Silkworth's 'allergy' a little bedraggled; Popeye Doyle untouched, as ever.
