1. A system for use with a drug delivery device, the system comprising:
- a sensor unit; and
a deactivation unit operatively coupled to an output of the sensor unit and to a drug-retaining region of the drug delivery device, the drug-retaining region containing a drug, the deactivation unit having control circuitry and one of either an energy source or capsules, the deactivation unit to apply the energy or the capsules to the drug-retaining region,wherein the sensor unit is configured to detect a characteristic of a local environment to determine if the device is connected to a user and generate an output corresponding to a value of the detected characteristic, andwherein the deactivation unit is configured to render the drug ineffective by neutralizing the drug in the drug-retaining region when the output of the sensor unit satisfies a predetermined condition indicating that the device is not connected to the user.

Abstract
A system for use with a drug delivery device includes a sensor unit and a deactivation unit operatively coupled to an output of the sensor unit and to a drug-retaining region of the drug delivery device, wherein the drug-retaining region contains a drug. The sensor unit is configured to detect a characteristic of a local environment and generate an output corresponding to a value of the detected characteristic. The deactivation unit is configured to render the drug ineffective when the output of the sensor unit satisfies a predetermined condition.
