I used to grow kanna along with my K@. Me and my old mate would commonly chew a bit with coffee in the morning. It could make any day just 'feel good' by nature. You'll find in lower doses it may be slightly calming or energetic paired with a nice reduction of anxiety. When I would play with higher 'doses' of the bark-tasting succulent, it would become a ~very powerful mood enhancer and perked me up to observe and converse. There were times, because I have a tendency to overdo everything, that I would chew so much that I'm sure I almost killed my two remaining plants (especially since the stems apparently contain most of the major active alkaloid), and would find myself nearly in tears over past negative experiences with friends and family. The urge to heal old wounds was very present.
When I bought some kanna powder from a trusted K@ vendor and friend of mine, the experience was hardly as powerful, I guess nothing beats the real fresh thing, but the familiar effect was still there. I'll stick with my beloved kava until maybe one day when I get a nicer place, I can pick up growing again
Lets keep this discussion going, it'd be cool to know how we're making out with other herbs and meds other than kava.
