One San Francisco Girl Scout has come up with a direct-marketing campaign that would make the guys from Mad Men (and Peggy) proud.

After setting up shop outside the Green Cross medical marijuana clinic on Monday, Danielle Lei sold out of cookies in just 45 minutes. Her mom, Carol, was there to help her out and make sure that she learned something from the experience.

“They learn that they’re not drugged out,” Carol told the East Bay Express. “Many have serious needs, and are just a little different.”

“And they get very hungry after!” added Danielle, 13. “I can’t smell anything because my nose is stuffed up.”

Coincidentally, one of the most popular strains of pot sold inside the dispensary is called Girl Scout Cookies. Now, thanks to the Leis, Green Cross customers can purchase very different variations of that product on either side of the dispensary door.

Danielle has until March 16 to hit her target of 1,200 boxes and she’ll try to make that happen later this week. According to the Green Cross Facebook page, Danielle will be back on Saturday.

“As promised, the Girl Scouts will be returning to The Green Cross!,” according to a post on Facebook. “They’ll be here from 4-6 pm this Saturday, February 22. So come support this great cause and enjoy some delicious Girl Scout Cookies in the process! Half the proceeds will go toward Alzheimer’s related charitable causes. Cookies, cannabis and charities, what more can you ask for!?”
