How can something that has no addictive elements and that doesn't enter your body be addictive? What a stupid study! It's obvious that they are not addictive at all, on the other hand, tobacco, alcohol, cocaine, etc. are addictive. Videos, like movies, series, sports, etc., are just another hobby, nothing more than that, they are not addictive. So this is stupid from any angle. And that supposed study doesn't make any sense.
