To be fair, some people have died from caffeine overdose when ingesting pure caffeine, which lead many internet retailers to not carry them any more. Example:

  What the hell does fair mean then? I've never taken GHB and don't plan to, but it looks like a recreational dose is ~1/2 of a dangerous dose, both of which would be (at least somewhat) difficult to obtain. With caffeine, the typical recreational dose is a beverage that is easily obtained and isn't dangerous. That you could buy caffeine powder doesn't make that a typical way to consume it. Apparently 500 mg of caffeine is considered potentially dangerous. That would be 5 or 6 cups of coffee (I'm in the habit of drinking that much coffee and have a pretty low resting heart rate during the consumption, so I dunno).
