There are no hard figures on how many "Mary Janes" there are in the legal retail marijuana business in Colorado, but at the Cannabis Summit, women made up at least a third of the attendees.
Murray said it's still a male-dominated industry, but women can make inroads if they have the stomach for it. "To be in this industry, you have to be bulletproof," she said. "You have to be steel."
You might say that about competing in any industry, but pot brings its own unique challenges. Colorado is, to an extent, making up the rules as it goes along for things like labeling, limits on THC in edibles, packaging and mandated security measures.
This remains an all-cash business as banks refuse to let pot businesses open accounts or get lines of credit. There's talk of creating a banking cooperative for the industry, but some fear that would be too risky.
"I would be very scared to expose our money, and then, for any reason, be at risk for any type of laundering," Gehring said.
Finally, even as some vendors begin pitching their services to the marijuana industry, others still shy away—and not even a woman's touch can change that.
Murray said it took her 10 phone calls to find a waste management company willing to take her trash, and some scientific companies refuse to sell her lab equipment.
"Shame on them," she said. "It's going to be a billion-dollar industry."
