What is surprising is that Harris and Kleibold were not tested for controlled substances.

If they were tested and came back negative, I didn't hear about it.

It wouldn't surprise me if the only drug they did was sniffing glue.

It's hard for me to imagine them committing that mass act of depravity unless they were mentally impaired by drug use.
