[4] Mazatec shamans have a long and continuous tradition of religious use of S. divinorum to facilitate visionary states of consciousness during spiritual healing sessions.
[7] Its native habitat is cloud forest in the isolated Sierra Mazateca of Oaxaca, Mexico, where it grows in shady, moist locations.
[8][9] The plant grows to over a meter high,[1] has hollow square stems like others in the mint family Lamiaceae, large leaves, and occasional white flowers with violet calyxes.
Botanists have not determined whether S. divinorum is a cultigen or a hybrid because native plants reproduce vegetatively and rarely produce viable seed.
[6] Salvia divinorum is native to the Sierra Mazateca in Oaxaca, Mexico, where it is still used by the Mazatec, primarily to facilitate shamanic visions in the context of curing or divination.
[31] Here too there are other candidate plants, notably cacahuaxochitl (Quararibea funebris),[32] Salvia divinorum has large green ovate (often also dentate) leaves,[33] with a yellow undertone that reach 10 to 30 cm (4 to 12 in) long.
Its most common habitat is black soil along stream banks where small trees and bushes provide an environment of low light and high humidity.
In 1962, the Swiss chemist Albert Hofmann and ethnomycologist R. Gordon Wasson traveled throughout the Sierra Mazateca researching Mazatec rituals while looking for specimens of the plant.
[26] These specimens were sent to botanists Carl Epling and Carlos D. Játiva, who described and named the plant as Salvia divinorum, in reference to its use in divination and healing by the Mazatec.
The plant's partial sterility was suggestive of a hybrid origin, though no two parent species have been found with an obvious affinity to Salvia divinorum.
[33] Similar to many psychoactive herbs, Salvia divinorum synthesizes and excretes its active constituent (salvinorin A) via trichomes, of the peltate-glandular morphology, located just beneath the cuticle (subcuticular) layer.
[75] Therefore, in what's understood to be a modern innovation, the 'quid' of leaves is held in the mouth as long as possible in order to facilitate absorption of the active constituents through the oral mucosa.
It may be taken diluted with water just before use, which may slightly reduce the intensity of its effects, but can also serve to lessen or avoid a stinging sensation in the mouth caused by the presence of alcohol.
[82] The relatively recent emergence of Salvia divinorum in modern Western culture, in comparison to its long continuing traditions of indigenous use, contrasts widely differing attitudes on the subject.
Opinions range from veneration of the plant as a spiritual sacrament or "a gift from the gods",[24][86] to a "threat to society", to be banned as quickly as possible in order to "spare countless families the horror of losing a loved one to the relentless tentacles of drug abuse".
In a local news report aired on ABC affiliate WJLA in Washington, DC on July 11, 2007, the anchors are seen to exchange expressions of incredulity when referring to a salvia story with the following introduction "Now, an exclusive I-Team investigation of a hallucinogenic drug that has begun to sweep the nation.
[68][97] A particular focus of many US media stories is the long-running coverage of the case of Brett Chidester,[95][98] a 17-year-old Delaware student who committed suicide in January 2006 by carbon monoxide poisoning.
[99] Although the Chidester story has been given continued exposure by US media, there has not been anywhere else, either before or since this controversial incident, any other reported cases involving or alleging Salvia divinorum as a serious factor in suicide, overdose, accidental, or any other kind of death.
"[101] In 2007, videos were shared on YouTube of alleged salvia users laughing uncontrollably, apparently unable to perform simple tasks or to communicate.
[nb 4] Nebraska Senator Vickie McDonald responded with "Anytime anything's on YouTube it's an issue," and "Legislators, parents, grandparents, we need to be on top of these things,"[108][109] McDonald proposed Schedule I listing Salvia divinorum as part of their Controlled Substances Act, under which possession of salvia would have been considered a Class IV felony with a penalty of up to five years and trafficking would have fallen under a Class III felony with up to a 20 year penalty.
[109] In Massachusetts, YouTube videos were shown by a retired police officer to public health and judiciary committees as evidence in favor of outlawing it there.
[115][116][119] In the United Kingdom, following a local newspaper story in October 2005,[120] a parliamentary Early Day Motion was raised calling for Salvia divinorum to be banned there.
[125] A schedule 9 drug is outlined in the Poisons Act 1964 as "Substances which may be abused or misused, the manufacture, possession, sale or use of which should be prohibited by law except when required for medical or scientific research, or for analytical, teaching or training purposes with approval of the CEO.
"[126] National legislation for amendment of the Controlled Substances Act to place salvinorin A and Salvia divinorum in Schedule I at the federal level in the United States was proposed in 2002 by Representative Joe Baca (D- California).
Those opposed to bill HR 5607 include Daniel Siebert, who sent a letter to Congress arguing against the proposed legislation,[127] and the Center for Cognitive Liberty and Ethics (CCLE), who sent key members of the US Congress a report on Salvia divinorum and its active principle,[19] along with letters from an array of scientists who expressed concern that scheduling Salvia divinorum would negatively impact important research on the plant.
[7][133][134] Several other states have proposed legislation against salvia, including Alaska, California, Florida, Iowa, Maryland, New Jersey, New York, Oregon, and Pennsylvania.
[139] Concerns expressed by some politicians on the subject of salvia reflect those of the media, with comparisons to LSD and particular focus on "protecting our children" being echoed;[89][140][141] and with legislative proposals following soon after news stories breaking.
[146][147] Opponents of more prohibitive measures against salvia argue that such reactions are largely due to an inherent prejudice and a particular cultural bias rather than any actual balance of evidence, pointing out inconsistencies in attitudes toward other more toxic and addictive drugs such as alcohol and nicotine.
[153][nb 7] Despite its growing notoriety in some circles, media stories generally suggest that the public at large are still mostly unaware of salvia, with the majority perhaps having never even heard of it.
[98] Although published responses may not necessarily be representative of public opinion as a whole, some news agencies generally support reader and viewer feedback in connection with their stories.
