Suburban Seattle, a major tech center, has become a hub for help for so-called "tech addicts," with residential rehab, psychologists who specialize in such treatment and 12-step meetings."The drugs of old are now repackaged. We have a new foe," Cosette Rae says of the barrage of tech. A former developer in the tech world, she heads a Seattle area rehab center called reSTART Life, one of the few residential programs in the nation specializing in tech addiction. Use of that word — addiction — when it comes to devices, online content and the like is still debated in the mental health world. But many practitioners agree that tech use is increasingly intertwined with the problems of those seeking help.
