I have some but I almost never use it since the initial a handful of times. It's kind of a crappy herb (probably why it's still legal). Effects can be intense but doesn't last very long (about 10 min).
I don't think it's like as acid. For one thing, you don't get any visual distortion with salvia. You may get some out of body experience if you smoke a lot of it but it's more like a calm "hmmm...that's kind of unusual...where am I" as oppose to acid's "ugghh....what the f*ck is going on...I can't tell if it's a dream" experience. But most likely, if you just smoke a little, you just end up giggling uncontrolably for 10 minutes.
