When Andy Cookston and his wife opened Denver's first medical-marijuana dispensary three years ago, they hung no sign outside their door.
They did no advertising; patients were drawn exclusively by word of mouth. They were unsure whether the state would even allow them to include their dispensary's full name — Cannabis Medical Technology — on their business license because of its pot-tinged terminology.
Such modesty is no longer a concern.
"Now that the door's been cracked open," said Cookston, who also owns a graphics company, "people are rushing it."
Colorado's medical-marijuana industry — just in its infancy — is already in the throes of a dramatic change.
