The amount dispensaries charge for an ounce of cannabis in Colorado varies radically from place to place.

As evidence, check out the latest Colorado numbers from PriceofWeed.com, which uses a crowdsourcing approach to gathering its data.

The priciest figures for high-quality marijuana are more than twice as hefty as the lowest ones — and the farther a buyer is from the Denver metro-area (or, in one instance, Colorado Springs), the likelier he or she is to pay a premium price.

Of course, the term “high-quality” is imprecise, and costs vary from place to place in any community with multiple dispensaries. But the digits still indicate that importance of location, location, location.
