I've used this vendor's kanna before and can testify towards its quality, but I'm a little upset that I paid 2.95 for a single gram of material. I decided that I didn't need a half ounce so I went with a sample size instead. The product description didn't mention how much kanna was included in the sample, but I assumed it would be a little more than 1 gram. (Posted on 3/2/2014)
I never heard about kanna, but after sampling m&m's kava I was curious. If used correctly, a very small amount goes a long way. Great addition to other supplements or by itself. (Posted on 5/26/2013)
