Khronic, check out the first couple posts in this topic... i covered a lot of them with some detail. For more info check out www.erowid.org it's got information on every drug/plant you can get your hands on. Most of these plants aren't used to get "high", they're entheogens which means they're used more for spiritual/meditation use. Even though they're legal, some have profound effects, just search around and learn learn learn!
