TORONTO — In a daring marketing ploy, the indie film company A24 has struck a deal with a Los Angeles medical-marijuana dispensary to sell two new cannabis strains under brands associated with Kevin Smith’s outré horror flick, “Tusk.” The film, about a guy who is slowly turning into a walrus, is set for a world premiere at the Toronto International Film Festival on Saturday night.

The medical marijuana will be available at the Buds & Roses dispensary in the Studio City district of Los Angeles from Monday to Sept. 26 under the brand names Mr. Tusk and White Walrus.

“White Walrus, I’m told, is more mellow and uplifting,” said Graham Retzik, an A24 marketing strategist, in a phone interview.

Mr. Tusk, he added, is supposedly more intense.

“The two are surprisingly complex, in keeping with the spirit of the film,” Mr. Retzik said.
