Compliance Carl

Compliance Carl is the buttoned-up, slightly rumpled, deeply caffeinated owl behind The Regulator Brief. Each week, he sorts through the fine print, policy shifts, market moves, enforcement updates, and regulatory curveballs shaping cannabis, hemp, cannabinoids, and other highly watched industries. When he is not reviewing agency updates or circling questionable language in red pen, Carl can usually be found muttering “context is everything” from beneath a stack of newsletters.
