“An ever-increasing craving for an ever diminishing pleasure is the formula” [for an addiction]. (Paraphrase of C. S. Lewis in Screwtape Letters)
Addictions, whether physical or psychological, rarely occur instantaneously. Usually, there is a satisfying “taste” that encourages a second, and then a third, ad infinitum. Before you know it, you can be captured by a “need” that is overwhelming and, often, almost incurable. We must discourage even the first “trial” of any addictive substance or behavior.
