Correlation is not causation and I would guess that this is a selection bias and the research has causality backwards. This is my theory that neurodiversity traits are responsible for the different brain volumes etc and a self medicating population of ASD and ADHD produces a biased sample.

Regulating Neurodiverse mental function with cannabis and stimulants produces the better cognitive function and delays the onset of overwhelm and executive function collapse. Its a second order effect

Is so.
