Are composite bats illegal in arizona or any state?

Well I am a freshman at Highland High School in Az and i have the 2011 demarini voodoo. i recently heard and read in many articles that the nfhs has banned composite everywhere and i am not sure if my bat qualifies as illegal. the voodoo is made of pitch black plus composite on the handle and a special alloy on the barrel. I have also read in the articles that these "hybrid" bats made of half comp. and half alloy don't count as illegal. Will someone please give me a specific clarification in order to prepare for the fall ball and regular season and if illegal please reccomend another bat 300$ and less to buy.
