The ceiling effect refers the dose at which the highest "opiate effect" is felt, and adding more will not change the effect. The way you feel at 4-8mg is the same way you feel at 24mg, regardless of whether all the receptors are occupied or not.

The ceiling effect is NOT the dose at which all the receptors are filled.
