The patient crushes extended-release pain medication tablets in order to obtain relief immediately. Which term describes the action of this patient?

Choice A reason: Dependence is physiological reliance; crushing for speed isn’t dependence but alters delivery, not fitting the chronic need-based pattern of dependency. Choice B reason: Abuse seeks euphoria or excess; crushing for relief manipulates timing, not intent, distinguishing it from recreational or harmful overuse patterns. Choice C reason: Misuse is incorrect use; crushing extended-release voids its design, delivering a bolus dose unsafely, matching the patient’s action precisely. Choice D reason: Underuse is insufficient dosing; crushing increases immediate effect, not reducing intake, making this the opposite of the patient’s medication alteration.
