Gordon doesn't strike me as being a true drug addict, and I'm not sure I'm even convinced he's a serious user. I am what some have described as a walking encyclopedia, and when you have that much minutiae floating around in your brain, if someone were to listen in, I'm not sure what they'd think. Freeman's likely had some experience with drugs, but he doesn't strike me as someone who's walking around high any portion of time.

Yes. Also damn, I was gonna say that. But then I'm also glad to see someone else has made the connection. (Oxycodone and Hydrocodone, essentially the same, but some slight differences.)
