Hmmm....so you mean there is a high probability that youth's on their phone all the time might also be misusing substances. Interesting. Thoughts? I wonder if the people making the tests have an issue with it and how they came about studying it. I mean, who are the individuals who placed so much value in it, and by value I mean money. How much is facebook and twitter worth? I wonder if what were studying to understand is more a reflection of what we value and if their is a contradiction of what we want as opposed to what we are creating. Perhaps a bit too deep, but I personally wouldn't get too overwhelmed into studying the disorder of social media as opposed to understanding the torn social dynamics, specifically generational value and appreciation gaps. Those I have yet to see studied.
