Is computer game the addiction the same as other kinds (ie drugs)?

I’ve just been sitting here doing my lab work and part of it got me thinking about the similarity between computer game addictions – such as online games – and that in drugs. You can argue that both contain reinforcement and withdrawal effects in certain people but to what extent are these addictions the same?

I will not lie, when I was younger I was addicted to online games to the extent it housed all my entertainment needs. However I found that after years it got boring, and subsequent games that I played equally got boring to the extent I am not an “addict” anymore. However I believe this is not true for other addictions such as drug abuse. I have never heard of anyone getting bored of meth and whatnot.

So what extent are these addictions the same? Do you have any experiences, evidence or explanations that will be enlightening? Or is there anything else that can build upon these ideas already stated?
