Neurons: Science Fiction

Drug addiction rates were sky high up on the rocket rocks. Something about neurons not being formed new as much. It was a lot harder to kick anything. People got obsessive, even the straight-edgers. They'd play their vids for forty-eight hours straight, or eat nothing but oranges for a week or more. The doctor tried his best to keep them all on an even keel, but the man was addicted to stims himself. And if the doctor went down, knowing the causes and the signs and all, what chance had the rest of them? When it got too bad they'd be shipped to rehab down on Earth, out of the radiation belt that slowed new neuron development. Had to do that anyway, after you'd been up for a certain amount of time. Your brain got to running a little slow.

Story Potential: Medium.
Notes: Kinda interesting setting, I guess.
