A group of concerned parents in Arizona has only one Father's Day request this weekend: please support legalizing recreational marijuana for the sake of keeping cannabis out of the hands of kids.

On June 16, the Arizona-based Parents for Responsible Regulation held a press conference to unveil a billboard that showed a father standing next to his young son with the caption, "Please, card my son. Regulate the sale of marijuana and help me keep it out of his hands." The poster also includes a link to regulationworks.org - a website discussing how legalization will keep kids safe from cannabis.

The billboard was released in support of Arizona's Campaign to Regulate Marijuana Like Alcohol (CRMLA), a 2016 ballot initiative backed by the Marijuana Policy Project. During the press conference, Ryan Treacy - PRR Co-Chair and a father of two small children - explained why parents should support legalization:

"Our current system of marijuana prohibition has failed to keep marijuana out of the hands of teens. It forces marijuana sales into the underground market, where customers are never asked for ID....In a regulated system, checks for proof of age would be mandatory and strictly enforced. I would do everything in my power to protect my children, and that's why I am speaking out in support of regulating marijuana like alcohol."

This is the second parent-themed billboard to come out of Arizona's legalization effort. In May, CRMLA celebrated Mother's Day by encouraging Arizonians to help breakdown stigmas surrounding cannabis by having a serious discussion about marijuana with Mom.
