Why are women attracted to this industry? Could it be that they do well here because customers feel more comfortable with a woman behind the counter or running a business as marijuana tries to shake its shady image? I think it starts from the compassionate side of medical marijuana, said Jaime Lewis, chief operating officer of Good Chemistry. We were able to take care of people and allow them an alternative way to medicate outside of pharmaceuticals and what their doctors were recommending for them. Lewis is a former professional chef from San Francisco who began making edible marijuana products for AIDS patients. Now she's in Colorado baking and selling full time for both medical and recreational consumers. I strongly believe there's that compassionate edge to it that attracts most women to the business, Lewis said. 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. - NBC News
