Gosh that really upsets me. I am a Baptist (very right wing Protestant) and I see NOTHING wrong with drinking kava. Kava does not alter your mind. You are the same person albeit, a bit happier, but that is it. I'm sorry that is a stigma that some missionaries or local church's have put it on it. It is an awesome plant that improves creativity, conflict resolution, and happiness. There is nothing wrong with that.
As a Christian I have never once gotten a conviction about it. In fact, I feel I have been encouraged to tell more people about this wonderful plant. Why? Because even though I am happy in the Lord, content, and He has blessed me more than I deserve. Life is hard and it's brutal Sometimes you need the ability to unwind, relax, and smell the ocean breeze. Kava allows you to do that without changing who you are and without being harmful.
