1999), the oral detection of exogenous substances plus the resulting stimulation with the compensatory response can be a highly delicate and specialized mechanism, ready to respond to really compact doses.

Fig. 3 demonstrates the outcome of abrupt modifications in drug dose. As famous higher than, tolerance to a drug remains current for a long period.
