Actually...
Cocaine is a dopamine mimic, and therefore it causes a huge amount of that neurotransmitter, causing a good feeling (and tons of side effects), which is what's addicting. Video Games aren't a chemical, so they can't be considered nearly as addicting since the increased dopamine is controlled by the brain, and it's not getting everywhere. You don't get addicted to video games unless your body reacts horribly. There's no physical addiction. It's psychological.[/b]
