Is kava legal in the US military?

I'm curious about the legality of KAVA within the US military. Can military personnel consume kava without facing any legal consequences? Does the military have any specific policies or regulations in place regarding the use of kava? Is there any evidence to suggest that kava may negatively impact military personnel's performance or safety? It would be helpful to know the current stance on this matter, as I'm considering incorporating kava into my personal wellness routine.
