i’m not sure whether there’s any physiological basis for this, but subjectively having an addiction feels a lot like having an additional need in the same vein as hunger and thirst. The addict’s mind is convinced it does “need” the substance.
It’s worse than that for e.g. alcohol and opiates. The organism lets the addict know in no uncertain terms it needs the substance. It’s not a choice the mind does unless you’re a zen master or something.
