From www.sagewisdom.org/usersguide.html:
“Salvia divinorum is an extraordinary visionary herb. It is not a recreational drug. It produces a profoundly introspective state of awareness that is useful for meditation, contemplation, and self-reflection. Its effects are unique and cannot be compared with the effects of other drugs. The effects of Salvia do not appeal to many people (young or old). The people who are most drawn to it are both mature and philosophically minded. Beware of inaccurate information. There are many unethical vendors who try to lure naive customers by portraying the effects of Salvia as more appealing than they are. The news media often sensationalizes stories about Salvia, exaggerating its effects, risks, and popularity. Much of what has appeared in the popular press is inaccurate and misleading. Salvia is not ‘legal pot.’ It is not ‘legal acid.’ It is not a substitute for any other drug. Before trying Salvia, it is important that you know about its effects, appropriate uses, and the potential risks associated with irresponsible use.
“Do NOT use Salvia until you have read through this guide. Salvia is unique. You cannot make assumptions about its effects based on experiences you may have had with other herbs or drugs. Salvia has much to offer: fascinating psychoactive effects, sensual enhancement, magical journeys, enchantment, apparent time travel, philosophical insights, spiritual experiences, and perhaps even healing and divination. It should not be used casually. It should always be used in a thoughtful, intelligent manner, and only by responsible adults that are of sound mind and clear intent.”

I’m really happy y’all have posted this user guide. I recently started working with herbalist Ginger Webb here in Austin, TX although she says that she has not consumed any yet she believes that the trouble with it is the extraction, not just using the leaves. This guide agrees with that and I hope that folks can get their minds around the difference! She also mentioned that from accounts she has heard, the effect is like dreaming awake.
Be Good to yourself & Love,
