Is weed legal in Arizona?

Excuse me, could you possibly clarify something for me? I've been hearing some conflicting information, and I'm hoping you might be able to shed some light. Specifically, I'm wondering about the legality of weed in Arizona. I understand that laws vary by state, but I'm having trouble pinpointing exactly what the current stance is in Arizona. Could you possibly provide a brief overview of the legality of weed in that state? Your insight would be greatly appreciated.
