I like it as a recreational thing. Kava gives anxiolysis comparable to 10 mg Diazepam but cognition remains sharp, the effect lasts about 1-2 hours. I also find it to increase sociability and make me enjoy things like music more.
Kava is not addictive, perhaps because it tastes damn awful? haha. I use Kava King vanuatu blend but I need 6-12 teaspoons to get a real high from it.
