Evidence that it's not addictive comes most tellingly from the United States' Drug Enforcement Administration: "The percentage of first-time users who become regular abusers of the substance is also difficult to determine; however, one Internet distributor indicated that only 1 in 10 customers places a repeat order for the drug...
Salvia divinorum most likely will not become widely abused"(DEA 2003)
Further indications that the continuance rate is low come from a survey conducted at a large university in Florida (Khey
et al. 2008
). An abridged version of the notes I took from this source:
Quote:Of those surveyed, 6.5% had ever used the drug (3.8% of females and 10.9% of males), 2.9% in the past year, 0.5% in the past month. Rating how pleasant or unpleasant the effects were on a scale of 1-10, the average response was 5.83 (not particularly pleasant or unpleasant). Asked about a desire to use the substance again, 51% said no, 32% maybe, and 17% yes. [It may or may not be prudent to mention this final point: Somewhat curiously they suggest that “successful measures of marijuana prevention may also have success when applied to Salvia divinorum”... But to my knowledge the only successful reduction of the use of cannabis has come in Holland as a result of legalization, and this measure obviously cannot be applied to a plant which is already legal; in fact, my personal interpretation of this statement (though probably not the authors' intent) is an endorsement of keeping S. divinorum legal!]
As far as its antidepressant effect goes, there are preliminary indications an Australian psychiatrist... here are the notes I took from his papers:
Quote:A 2001 case study reported on a subject with a five year history of clinical depression who found regular use of sub-intoxicating doses of S. divinorum provided a total remission of her depression symptoms (evaluated by the Hamilton Depression Rating Scale) as observed over the course of six months. Her regular dose was 2-3 leaves (0.5-0.75 g dried material) chewed an held in the mouth for 15-30 minutes, three times a week. Minimal side effects were reported: occasional lightheadedness for up to an hour after consuming the herb. She discovered the antidepressant effect after smoking the herb. She also reports benefits from occasional intoxicating doses of 8-16 leaves (2-4 grams dried) taken orally, including a “psychospiritual awakening” and greater self-confidence. (Hanes 2001) Hanes later reported having introduced the herb to five more patients, with the majority reporting positive effects (and none reporting any deleterious effects). With regards to larger doses explored by some subjects, Hanes acknowledges that “the personal growth and healing significance of integrating such experiences into the lives of those bearing such symptoms as hopelessness, worthlessness, loss of interest/pleasure in all activities and difficulty finding ‘meaning’ in their lives cannot be underestimated,” and further suggests the plant may have potential beyond the treatment of refractory depression, e.g. in the development of human potential. (Hanes 2003)
Daniel Siebert has received dozens of anecdotal reports from people addicted to alcohol or other drugs who have “cured” their addictions using
S. divinorum, as well as similar testimonials from individuals alleging that it alleviated their depression (Ketcham 2007)
Here's the abstract (Baggott
et al. 2004) of a survey of 500 people who had used the plant (considering Earth and Fire Erowid are coauthors, the data was presumably collected via erowid.org):
Quote:Salvia divinorum (SD) is a legal psychoactive plant that produces hallucinogen-like effects through a putative kappa opiate mechanism. We characterized the reasons, methods, and reported consequences of SD use in a sample of 500 users (92.6% male, 23.4±8.7, range 13-68 years) with an on-line questionnaire. They had used 13.3±22.9 (range 1-250) times, usually to explore altered consciousness or to have a spiritual/mystical experience. 80.6% probably or definitely would use SD again. 92.6% smoked SD with 61.4% using a concentrated extract and 37.3% using dried leaf; effects were estimated to last 14.1±12.8 minutes. Compared to other methods of altering consciousness, SD effects were felt to be unique. Common (>25%) after-effects of SD included feelings of increased insight (47%), improved mood (44.8%), calmness (42.2%), increased sense of connection with the universe or nature (39.8%), weird thoughts (36.4%), things seem unreal (32.4%), floating feeling (32%), increased sweating (28.2%) and body felt warm or hot (25.2%). 25.8% reported persisting (>24 hr) positive effects (usually an increased sense of well-being) on at least 1 occasion. 4.4% had persisting negative effects (most often anxiety). 0.6% had sought professional help for a SD-related problem. At some point, 0.6% felt addicted to or dependent upon SD; 1.2% reported strong cravings for SD; 0.4% endorsed three DSM-IV dependence criteria. We conclude that SD is commonly used and merits further study.
A factoid you can use regarding responsible use: There have been no documented cases of individuals attempting to drive under the influence of
Salvia divinorum (Griffin et al. 2008
). [Sidenote: Unfortunately I personally know of one such occurrence, where some passengers deliberately deceived a friend of mine while he was driving (telling him the pipe was loaded with cannabis, which, like many chronic users, he was comfortable driving under the influence of); fortunately no accident occurred as a result of this horrifying lapse in judgment. And since it ain't in the literature, it's probably best not to mention it]

I suspect a great deal more supporting data may be found in the literature on the pharmacology of the plant, but I haven't started tackling that subject yet; I'd been planning on saving it until I finish my notes on the chemical literature regarding
Salvia divinorum. I'll try to get around to more pharmacological sources in the near future and post relevant info as I find it; in the meantime, a great deal of that literature is available online, so other Nexians can skim it for useful data and references as well (I'll provide a list below with urls)
One final point: The best general reference for background historical info on
Salvia divinorum is Jonathan Ott's paper from 1995 (of course it predates the discovery that salvinorin A acts at the kappa opioid receptor and the climb in popularity that the plant has seen in the past 15 years). Daniel Siebert has a transcription of it available at
http://www.sagewisdom.org/ott2.html [Full Citation: Ott, J.
1995. "Ethnopharmacognosy and human pharmacology of
Salvia divinorum and salvinorin A"
Curare 18(1): 103-29.
