There's plenty of reputed legal highs out there and plenty of feedback, but I feel that Kanna (sceletium tortuosum) is one of the least popular. This puzzles me since Kanna is effective in fairly small doses, quite cheap, and quite pleasant. It's definitely not a "high" in the sense that Kratom, kava, or our beloved illicit substances are, but it produces a nice boost in mood and potentiates the hell out of weed. I used to snort some Kanna before my lab every week and those two hours just flew by. So I just wanted to spread the word about this lovely plant in the hopes that other will enjoy it as much as I did.
I don't mind it, really. I find that when I take it orally, it has some relaxing, anti-anxiety effects (it's apparently a mild SSRI). I tend to close off from the people around me and sit in my own world when I take it, it makes interaction with other people seem unimportant, which I like.
problem is also that you have to get the South African kanna as that is where it grows. A reputable seller and grower will be ethnoshaman.com - cheap and potent
