How it works

How cannabis is sold in Northglenn

Northglenn is the odd one among its neighbours: it sets no store cap at all, and Thornton, a short drive away, stops at four.

City	Store limit	Detail
Northglenn	No numeric cap	A half-mile from other marijuana businesses, 8 a.m. to 10 p.m., seven days, according to the city code.
Thornton	One store per quadrant	Four stores in all, every one operating, and no applications being taken, per the city.
Commerce City	Four per area	No new licence until an area has fewer than four stores; Area 1 has seven.

Spacing: half a mile between marijuana businesses
Hours: 8 a.m. to 10 p.m.
Court test: Colorado Supreme Court, April 2017

What does half a mile do?

It spaces the six listed stores: Callies on West 104th Avenue, Doc's Apothecary on East 112th, Fresh Cannabis on Cherokee Street, Green Tree on Melody Drive, Igadi on Washington Street and Discrete Greens on Claude Court. Further tests apply: 200 feet from homes, 500 from child care and parks, 1,000 from schools and colleges. Northglenn licenses through hearings, not a lottery.

Why was Northglenn in court?

The Cannabist reported in April 2017 that the Colorado Supreme Court backed the city's local licensing ordinance in a case brought by Rocky Mountain Retail Management. The case gave the city's own licensing process the court's backing. Statewide buying rules: Colorado.
