Legitimately very interested to see a comparable study for cannabis, in adult users.
[EDIT] everything I could find with a quick search is about heavy, long-term use only, which evidently has little effect on white matter, and uneven effects on grey matter, increasing it in some areas and decreasing it in others. Nothing about long-term light use, occasional "binge" use, anything like that.
