I wouldn't be surprised if that energy drink that Luthor was consuming was some kind of smart elixir he came up with. I look at all of this as younger versions of "All Star Superman" since this is partially based on Morrison's proposed "Superman: Year One" story that would have been a prequel to All-Star Superman.
As for Justice League #1...I don't have a problem with writers writing for trades. I have a problem with bad writing and atrocious dialogue of which there was in that book. I expect better from Johns who can and has done better with both things.

Another possibility is that Lex guzzles though to keep awake all night and day in order to play around in the lab.
