As prototypical incentive with biological meaning, food illustrates the distinction between money as tool and money as drug. However, consistent neuroscience results challenge this view of food as intrinsic value and opposite to drugs of abuse. The scarce availability over evolutionary time of both food and money may explain their similar drug-like non-satiability, suggesting an integrated mechanism for generalized reinforcers.
