White tablets taken from Klebold’s room: “per Sgt West, the tablets will not be analyzed.”(18701)
“Among the items police found in his room were two half-empty bottles of St. John’s Wort, an herb believed to elevate mood and combat mild depression. I asked one of Dylan’s friends if he knew that Dylan had been taking it. Dylan told him he hoped it would increase his "motivation."
– I Will Never Know Why” – Sue Klebold
“he’s either really hyper or really kicked back,” – Devon Adams
“Dylan was the same happy person that he normally is and was very talkative and friendly… with him joking a lot. Over the last month or so Dylan had become more and more withdrawn.” – Kelli Brown (10680)
In discussing any drug use that Tim was aware of concerning Eric Harris and Dylan Klebold Tim stated that he was aware that Dyian took some kind of energy pills that he bought at the store. – Tim Kastle (004322)
Jeffrey reported that he had noticed a behavioral change in Dylan the prior several weeks before the incident. He stated that Dylan was normally a very good student but had been falling asleep in the 2nd period class each day. The teacher kept threatening to throw him out of class if he fell asleep again but never did. And there were times in that several weeks that Dylan appeared unusually hyper and full of energy. – Jeff Marquardt (000988)
There is good evidence that St. John’s Wort may reduce symptoms in people with mild-to-moderate but not severe (or major) depression.
