Have tried a few different varities of these. Extract was made using water method. Got a definite effect but it was not the usual Kava effect. I felt slightly disorientated, a bit tingly on my skin and then felt quite tired afterwards. I found it difficult to think straight immediately after having it.
True, Kavalactones are damaged by heat but at the extreme heat of a vaporizer the Kavalactones do seem to react but in a different way than normal. I wouldn't be opposed to vaping Kava if it had the normal effect but I didn't enjoy what I felt. I will try other atempts at Kava E Juice though, for sure.
