Arizona has twice the national average of teens who admit they use methamphetamines, state Attorney General Terry Goddard said Friday.

Goddard spoke to a group of 24 students at Phoenix Prep Academy who were shown ``Not Even Once" television commercials on the dangers of meth in recognition of National Meth Awareness Month.

Goddard told the students that parents need to teach kids the addictive and destructive nature of meth, so kids develop ``that instinctive response, `No, that's not something I'll ever try."

He said meth use is a leading cause of child abuse cases, which are on the rise. ``Sixty-five percent of those cases specify meth as being the cause of child abuse, and we know the number's higher because other cases just say drugs."

The special screening was one part of the Arizona Meth Project's statewide effort to educate students during National Meth Awareness Month. The organization has distributed DVD's of the advertisements to schools across the state, with a letter encouraging them to run the clips during regularly-scheduled televised announcements.

Among those listening to the message, Danika Frimodig, now back in school after a battle with meth.

``The first time I smoked meth I was addicted," Frimodig said.

She offered this advice to parents: ``Keep a good relationship with your kids. Don't accuse them, but keep open communication. That's key."
