Based on the abstract (since the full article is behind a paywall) it seems as though they didn't study the brains over time . . . just compared pot-smoker's brains to "normal" brains. I wonder if there's any chance that the enlarged nucleus accumbens were pre-existing, and encouraged those people to smoke marijuana more often. In other words, is there any way cause and effect have been reversed?
