Looking for the finest weed? Turn to private purveyors, not the feds. New research finds that government-produced cannabis offers fewer variations and a lower concentration of cannabinoids than marijuana sold by dispensaries in states where the drug is legal.
The study was published in Nature on Wednesday, a day before the nation's unofficial marijuana holiday, April 20. (The publication date was pure coincidence, according to lead researcher Daniela Vergara.) Researchers at the University of Colorado Boulder and Steep Hill Labs Inc., a California-based cannabis testing laboratory, analyzed close to 3,000 samples.
