In corporate America, women hold about a quarter of leadership roles and less than 5% of CEO positions. But in the fledgling cannabis industry, women make up about 36% of leaders, including 63% of high-level positions at testing labs and half of leadership roles at infused products and processing companies, according to a survey conducted by Marijuana Business Daily.

In honor of 4/20—the 20th of April, which has become an unofficial marijuana holiday in the U.S—Fortune took a look at some of the pot industry’s female pioneers, including a “cannabusiness” investor, a dispensary owner, a grower, and a professional connector.
