It sounds interesting, but how can they tell if he's tripping out or not if he already has issues expressing himself normally? I guess if he's functioning at a higher level than usual, he's probably OK, but it still seems kind of iffy to me. Maybe it's just the stigma surrounding cannabis that's coloring my perception on this.

I wonder if a medical study for something like this would be feasible. I also wonder if there could be negative long term or developmental effects from a treatment like this.
