People who take methadone have always been surveilled at the clinic. When patients ingest their medication, a nurse watches and then asks them to lift the tongue up to inspect their mouth to see if the dose was swallowed. Staff watch patients when they urinate for toxicology screenings. New digital technology has been created that monitors people who take methadone in their homes. Sonara is a tech company that created an app called Virtual Dosing Window. Patients use their cell phone to video themselves swallowing methadone at home, then upload the video to a secure platform for clinic staff to review. The Verinetics corporation makes DispenSecur, a specialized lockbox that contains take-home doses of methadone. The DispenSecur device features GPS location monitoring, a real-time view to a dispensing activity log, and inventory tracking. Through geofencing technology, a Google map shows the “last known location” of the lockbox. Staff can remotely lock the device so a patient cannot access their medication. Sonara and Verinetics are funded by private equity investors and venture capitalists who see an opportunity to profit from technology that surveils methadone patients in their homes. This talk will describe how these "Big Brother" apps and devices work, how they are poised to disrupt and transform methadone dispensing, how they continue to stigmatize and disempower patients, and why these invasive and unnecessary surveillance technologies must be rejected.
