Unlike cocaine you can quit video games cold turkey without the possibility of death or internal injury. So your attempted argument starter is defused.
I can argue that video game addiction can actually result in possible death or internal (and external injury). Addictions are deep-set psychological (and/or physical) attachments to an activity. Drugs, smoking, video games, alcoholism, etc. If a person was to try and quit cold turkey, two things would be apparent: 1) The mind is going to start playing tricks, asking for that "hit", whether it'd be one smoke, one drink, one map. When you force your body to go without it, it then begins to rebel in other ways: cold sweats, tiredness, shaking on the physical spectrum; psychologically, anger, nervousness, jittery, etc.
Remember that video of the german kid getting upset with the game? Granted, it's more of a temper tantrum, but if you observed his behavior closely: He was gaining pleasure from playing the game, but soon kept getting killed. That resulted in anger, and he overreacted, busting the keyboard, smashing his fingers against it and the table. :chair: And then once done, he became extremely remorseful, and consoled himself with playing the game again. The situations aren't the same as an addiction like we're looking at, but in a way, the kid's behavior is a sign of addiction, and what he did speaks of what can happen to an addicted game. By which, I mean: They can become hostile and quick to anger, they can become psychologically unstable at times and moments, and during such times, they may react (or overreact), resulting in bodily harm to themselves or others. :facewall:
Of course, I'm just playing devil's advocate just for fun here.
