First of all, salvia is nothing like weed, at all. Salvia is a plant, not a root. I've smoked the leaves, the 10x, and the 20x. I smoked 6 bowls of the leaves in a row, and have also tried to make a quid(sp), which is were you pretty much just chew on the leaves for 30 mins or so, and it didn't do shit to me. I bought the 10x for $40 and it was not worth it in the least. I've tripped shrooms before, and it kind of felt like the feeling of shrooms when theyre first coming on, but different. I found it difficult to speak and form sentences and it sounded like I was slurring my words for 5 minutes or so, but I definiltey knew what was going on and where I was. The 20x was pretty crazy, its not worth trying to describe what happened because it won't make any sense. I've never tried the 40x or the 60x but im assuming their even crazier. You can buy salvia at most good head shops, but its always real expensive.
Honestly, I'd say its worth trying it once, but after that, its way too expensive. For all those kids who are asking about it check out
