How can one single effect of somthing like weed be the major factor in this happening it is an awful event to have a life taken but to said because of smoke, he has used cocaine and I'm sure that is not the only drug he used..how about the fact he did not take his medication for days before he wacked out? You would think they would look at that instead of something stupid as weed. What about the people w/cancer that smoke to be able to keep food down and their strength up bacause kimo-thearpy takes such a toll on their boddies, or all the patients that are given weed for glocomma even aids so isnt smoking weed allowing more to live peaceful and painless more important than someone not taking his medication, where are the parents in the why werent they keeping better track of their son and his meds, think that may be an issue that should be looked at. games are rated and maybe the parents should of looked at what thier son was doing and wondering if this is something their son should be playing with his mental problems, you cannot just pick one thing and say "so be it" thats the cause.., there is a larger picture here and no one seems to addrressing it.
