about salvia divinorum... I'm curious about this herb and the effects of smoking it. If you've tried it, there are a number of questions I have: 1. Is it legal in all states? 2. If so, where can the extract be obtained? 3. What's the process for smoking it (i.e. do you smoke the leaves, add the extract to something, or what?) 4. What are its effects? 5. How dangerous (if it is) is it? 6. How expensive is it? 7. Is it worth it?
