It's quite a head-turner.
A billboard recently went up near 3rd Street and Camelback Road.
It reads "The Marijuana Doctor" and has a giant protruding marijuana leaf on the ad.
The Marijuana Doctor is a clinic that provides recommendations to patients so that they can obtain a medical marijuana card.
Company spokesperson Micheal Peyron said they're trying to get rid of the stigma surrounding marijuana as a medicine, and that's why the ad is so eye-catching.
"It's the first step," Peyron said. "We're the first ones to get a billboard with a leaf and the word 'marijuana' on it, we're hoping this is just a stepping stone."
The billboard will be in Phoenix for a month, then moves to Tempe for another month.
