I'm not researching anything, its just my opinion based on my experiences.
What i mean is that the majority of users do not overuse it or use it often.
They just try stuff every now and then and its pretty much harmless, but there is still so many who starts off like that and then do it more and more often, and becomes addicted.
It's what i think, i've seen alot of other weird opinions posted in this thread and i felt like posting my own to try and show the problem from a different perspective
