1987, Peper 2004a). The papers argue that tolerance to some drug is not merely tolerance into the Attributes of a certain drug, but tolerance to a certain dose of that particular drug, and the magnitude of your compensatory reaction will not be based on the actual dose with the administered drug but because of the dose the organism anticipates. On top of that, the papers argue that the oral recognition of exogenous substances would be the normal and primary stimulus for the compensatory reaction from the tolerance mechanism.
