Retail marijuana labels in Colorado will have to include potency, expiration dates, safety warning

DENVER – Colorado has announced detailed rules for how recreational pot should be grown and sold starting next year. The state department that will regulate marijuana released more than 60 pages of rules Monday for how marijuana sales will be licensed and regulated. The Colorado Legislature set broad parameters earlier this year, but the nitty-gritty rules were left to the Department of Revenue. The voter-approved marijuana legalization measure adopted last year required the department to release rules by July 1. Retail sales don’t start until January, and the newly released rules don’t apply to medical pot shops. The rules require labels to include potency, expiration dates, and a disclaimer that pot isn’t legal outside Colorado and hasn’t been safety-tested.
