If you want to see the problems facing women in business, look no further than the cannabis industry. Not long ago the marijuana business was way ahead of U.S. business overall in the leadership positions held by women. But as the industry has become more mature and more mainstream, instead of building on that leadership, it’s going in reverse. Men are now edging out the women. The percentage of executives in U.S. marijuana-related companies who are women has collapsed to 27% from 36% in just one year, according to the latest anonymous survey by Marijuana Business Daily.via
