How much gaming is too much gaming?
This is the question Japan's pre-eminent addiction expert, Dr. Susumu Higuchi, is trying to answer as he treats people whose lives have been destroyed by video game addiction.
Online gaming addiction has become the fastest-growing form of addiction in the 21st century, and it's the most vulnerable people — children — who mainly fall prey to its psychoactive effects, Higuchi says. As head of the Kurihama Medical and Addiction Center in Kanagawa Prefecture, which started the country's first program for internet addition in 2011, Higuchi is rolling up his sleeves to tackle a scourge that has eaten into the vitals of our society.
