(for the record, I think there is a link between violence/desensitization and these drugs but...)
This immediately makes it clear whoever wrote this article is very confused about the whole thing:
“James Holmes the Colorado batman shooter, had taken 100 milligrams of Vicodin immediately before he shot up the movie theater”
What does that have to do with the topic at hand or the price of cheese curds in Wisconsin?
(Hint: Vicodin is an opioid and hepatotoxin (acetaminophen), not psychiatric related drug)
Heres an interesting article on that. Just scary.
