PALM DESERT, Calif. -

An actress who starred in "The Blair Witch Project" and an author will speak about marijuana growing at UCR Palm Desert tonight.

The 6:30 p.m. talk is the last event in the campus' Arts & Letters lecture series. The speakers are actress Heather Donahue and writer Mark Haskell Smith.

Donahue starred in the 1999 horror film "Blair Witch Project" at age 24, and 10 years later became a marijuana farmer. Her book, "Growgirl: How My Life After The Blair Witch Project Went to Pot," was published last year.

Haskell Smith reported for the Los Angeles Times on the Cannabis Cup blind tasting competition in Amsterdam and last year published a nonfiction book, "Heart of Dankness: Underground Botanists, Outlaw Farmers and the Race for the Cannabis Cup." He is an assistant professor in the master's degree program for writing and writing for the performing arts at UCR Palm Desert's Graduate Center.

Both authors will sign books after the discussion, and books will be for sale.
