Arizona may see a marijuana shortage after legalization

But, distributors could be faced with an even bigger issue.

There's no definite timeline for when medical dispensaries will be able to make the transition, but when they do, they may not be able to meet the high demand for cannabis.

Spencer Andrews is a public affair director for March and Ash, a dispensary in Imperial County. He addresses an important matter that happened when California made the switch.

"What we saw in California was a shortage in the supply chain. I mean, you're just working with many aspects of the supply chain: manufacturing, cultivation, testing, distribution," Andrews explained. "All of these ancillary services have to get up and running and be able to meet the demand."

All of these steps take time.
