"We ask a question: if a state actually does legalize marijuana for recreational use... what kind of things can we learn form the alcohol and tobacco industries in the way they've marketed to kids?" she said. "What can we do to prevent that (marijuana) industry from marketing to kids?"
She said setting a legal age limit of 21 is not enough.
"We do not trust the advocates who are trying to legalize marijuana because we don't believe they are willing to look at these other two industries (alcohol and tobacco)," Rusche said. "Everything we read in their initiative has to do with making money and not protecting kids."
If any marijuana initiative passes, Rusche said her group is interested in working with the state agencies that write the regulations in order "to force the industry to self-police rather than (have) the taxpayers pay for the cost" of any negative consequences, including addiction treatment and accidents caused by driving under the influence.
"We want people to take marijuana legalization seriously and think seriously about the consequences to kids," she said.
When asked about Rusche's concerns, Tvert said he was confident the marijuana industry would not target its product to minors.
"There's a great deal of self-regulating already taking place -- business owners not choosing marijuana leaves or cartoon characters," he said, referring to the medical marijuana industry. "It's an evolving industry (and) in theory, these are standards that are already being created."
That doesn't mean the marijuana industry won't advertise its product in places where children might be present, though.
"It's worth noting, every young person that walks into a professional baseball game in Colorado (at Coors Field) is walking into a beer commercial," he said. "So the notion that we somehow cannot possibly have marijuana legal because young people will somehow know about it and see it, is unrealistic."
