Seems as though they didn’t retest, they only scanned people once. Scanning people is expensive and getting people to show back up for a second scan is difficult. The abstention periods are likely based on self-reports.

With the low sample size of the study, I wonder how much of that is confounding variables. I know when I’ve been at my heaviest cannabis usage, my life was falling apart and I was using it to cope with a shitload of stress — which is known to cause short-term and working memory impairments.
