Guys, lots of good comments here, I'll just add one thing. In western medicine, as far as I know, anything that messes with Gaba-a becomes a drug-dependency. From what I understand there are three or four studies that show that Kava does not mess with Gaba-A, and two that show that it does. So they aren't 100% sure, but it is possible that Kava has a different route to the anxiolytic effects. That, or it does do it but it also simulatneously does something else that we don't yet understand. The other herb that has this effect but does not cause addiction is Valerian. I believe in both cases it is not well understood in the west how it can have these effects yet not cause any addiction. If I understand correctly, a large part of alcohol addiction is the Gaba-a interference and I know for benzo's that is the main part of it.
