KANNA Kanna has been used as a mood-altering substance. Traditionally, the dried plant material is often chewed as a quid, and the juices swallowed, but can also be made into teas and tinctures. It can also be inhaled as a snuff, or smoked, sometimes with the addition of other herbs. Sceletium elevates mood and decreases anxiety, stress and tension. Higher doses can cause euphoria, initially with stimulation and later with sedation. It has been suggested by some that Kanna can potentiate the effects of alcohol and cannabis.
