Beneath each full moon on the outskirts of a village in central Mexico, a group of women in nun habits circle around a roaring fire, cleanse themselves with burned sage, and give thanks for the moon, animals, and plants. Then they inhale deeply from a joint and blow clouds of marijuana into the flames. In the United States, where around two dozen states have legalized recreational marijuana, the group has also launched a successful small business, selling CBD tinctures, oils and salves online, and raking in over $500,000 last year.
