How Do We Find The Truth?
The simple answer is that Eric was on medication, but Dylan was not.
Dylan did not have any medications in his system at the time of his death which means he was not taking medication at the time of the shooting. And if Dylan was on medication at any point in his life prior to the shooting we won’t know unless his parents divulge that information to the public. There is no documentation available to the public that confirms Dylan being prescribed medication.
Eric, on the other hand, had therapeutic amounts of Fluvoxamine (Luvox) in his system at the time of his death. This was from the drug he was prescribed by his psychiatrist.
Did Luvox play a part in Eric’s choice to kill his classmates?
Some say that being on the drug alone caused Eric to feel homicidal and suicidal. But in Eric’s private journal he lamented about how taking Luvox made him feel too “normal” and he therefore stopped taking it to “build on the rage” so he could go through with the shootings. He was talking about eliminating everything that made him feel bad about it, including keeping a far distance from his parents.
If Eric admittedly stopped taking Luvox because it was making him feel good, then taking the drug alone probably didn’t contribute to his homicidal rage. While pharmaceutical drugs are very dangerous and often increase feelings of depression, they do actually work wonders for many people. It is fairly clear that Luvox was a drug that was working well for Eric. But no matter how great the drug may have been working for Eric, if he really did stop taking it without tapering off, the effects would have been severe. In that case, if he really did stop taking it – then the fact that he stopped taking it would have contributed to his rage.
But did Eric really stop taking Luvox as he claimed?
With therapeutic amounts of Luvox in his system, it is hard to believe that he stopped taking it. But it’s also possible that he only took it a day or two before the shooting.
We can’t ever know for a fact if Eric really stopped taking Luvox, despite his journal entries mentioning it. For all we know he could have stopped for a day – or a week. The medication was found in his system at the time of his death with a therapeutic amount which means he had taken a recent dose. But in order to determine how recent the dose was, we need to know how much he took. But there is no way we will ever know how much he took. Even if we know what dose he was prescribed that doesn’t tell us how much he actually took. There is reason to believe he was messing around with his dose, so basing any calculations on his prescribed dose isn’t going to be reliable. But we don’t even know his prescribed dose.
While it’s true that psychotropic medication can induce homicidal and suicidal thoughts in people (or enhance those that already exist), that isn’t true for everyone. We can’t really say that Luvox influenced the massacre. Eric documented the fact that Luvox made him feel normal and he had to stop taking it to feel his rage again.
I’m not saying that psychotropic drugs are harmless, but they each play a very unique role in people’s lives, and we can’t really determine what role Luvox played in Eric’s life.
Reasons to believe it:
Eric had Luvox in his system when he died
Eric’s records of prescription anti-depressants are public
Reasons to question it:
Dylan did not have any medication in his system when he died.
There is no indication that Dylan was ever prescribed anything, and his medical records are sealed and his parents aren’t talking.
