An ombudsman is defined as “a person who investigates and attempts to resolve complaints and problems.” We figure cannabis could use such a problem solver, and The Ombudsman is Green State’s advice and etiquette column. It’s written by Ngaio Bealum, who edited the West Coast Cannabis newspaper and is arguably the No. 2 weed comedian in America, behind Doug Benson. Bealum is a Sacramento-area father, a go-to host for cannabis events and a veteran world traveler. All of which make him a keen observer of human behavior and a reliable ambassador for grass. In this installment, Bealum provides tips for cannabis users returning after a decades-long break. Got a cannabis advice question for GreenState’s “The Ombudsman”?
