Addiction: Gaming

Well whaddya know? Gaming has been shown to be actually addictive in the same sense that say heroin, or crack is addictive. Yes that is right! An addicted drug user and an addicted gamer both share the same neurobiological behaviour as shown in a study that looked at brain scans of addicted drug users and gamers. (1) Another study found that certain images or "cues" from certain games were able to invoke cravings in addicted gamers (2).
