"To me, the 'canna-business,' it's a great example of community-level capitalism working well," says Heather Donahue, Hollywood actress-turned-marijuana farmer and author of the new book Grow Girl. Donahue sat down with Reason.tv's Tim Cavanaugh to discuss why she left acting only a few years after her iconic role as "Heather" in the Blair Witch Project and how she ended up cultivating marijuana in a small Northern California community known as "Nugget Town." Although Donahue favors legalization of marijuana and acknowledges the terrible toll that prohibition has taken, she also thinks that California's medical marijuana market has flourished in the legal "grey area" that currently exists. "By creating this grey area, you're actually creating a system that works," says Donahue. "This is a system on a human scale, and that's part of why it works so well." Approximately 9:43 minutes.
