Puff, pump, pass!

A marijuana dispensary in Colorado just opened the world’s first pot-friendly filling station — Gas & Grass.

After holding a soft opening on Thursday, the hybrid weed business officially opened up shop Saturday in Colorado Springs.

It is one of a dozen medicinal marijuana facilities owned by a company called Native Roots, which claims to be the first to pair fuel with cannabis.

Since it is illegal for pot shops in Colorado to sell non-marijuana products, Gas & Grass will feature two separate businesses with two different entrances — one for the dispensary side and the other for the gas.

“It’s really just kind of pairing the convenience in one specific stop,” Native Roots spokesperson Tia Mattson told local NBC affiliate KOAA.

“I believe we’ll have lottery tickets, beverages, cigarettes and similar things that you would pick up in a convenience store,” she said, describing the gas side. “It’s just one more thing for us to pair up the shopping and convenience of gas with a stop for somebody who is a patient, to knock off both errands at one time.”

But recreational bud-lovers will be bummed to know that the herbs being sold at Gas & Grass are for medical use only — so people will need a prescription from a doctor if they want to make a purchase.

To win over new customers, medicinal marijuana patients who shop at Native Roots will get loyalty discounts on gas, in the same way grocery stores such as Costco or Stop and Shop award patrons.

Members of the public who don’t choose to shop at the dispensary will be allowed to fill up at the station, as well.
