Schools are installing military-grade surveillance in the last private space students have left: the bathroom. 🚽 We investigate the booming $3,000-per-unit business of "Smart Vape Detectors" like the HALO Smart Sensor, which are turning restrooms into data-gathering nodes.

1. The "Aggression" Microphone: These devices don't just sniff for nicotine or THC. We expose the controversial "Aggression Detection" feature, which listens for "abnormal noise levels" and specific keywords like "Help." While companies claim they don't record audio, privacy advocates argue this effectively puts an always-on microphone in a bathroom stall, normalizing intrusive surveillance under the guise of safety.

2. The False Positive Trap: We break down the technical failures. These sensitive chemical sensors are frequently triggered by non-vape sources like body spray, cleaning products, or even steam. This leads to a "guilty until proven innocent" environment where administrators storm bathrooms based on false alarms, forcing students to consent to searches or face suspension based on flawed data.

3. The Cost of Control: With installation and software subscriptions, schools are spending tens of thousands of dollars—often from settlement money paid by vape companies like Juul—on tech that students defeat simply by exhaling into their hoodies. We ask if this massive investment is actually stopping addiction, or just creating a "Cat and Mouse" game that erodes trust between students and teachers.
