Articles bias

I am concerned by the implications of this page. There is a great deal of literature from France in the 1990's describing the effects of Absinthe but this article simply tries to pawn them off as imagination. I hope that someone will address this article's bias. The lack of science on such an obscure drug should not outweigh decades of writings on the experiences of users. 71.139.160.177 02:40, 28 January 2007 (UTC) Napa, CA[reply]

What literature would that be? What if the literature is inaccurate as many previous writings have been shown to be? What experience by what 'users'? -- Ari 02:49, 28 January 2007 (UTC)[reply]

Very biased page and same with absinthe page where this guy Ari is operating as link spammer Toga2 09:32, 16 November 2007 (UTC)[reply]

Can you explain this bias and provide evidence it is biased? -- Ari 15:58, 16 November 2007 (UTC)[reply]

There is a recent scientific study published in Journal of Agricultural and Food Chemistry (April 2008) regarding the chemical composition of vintage preban absinthe and thujone levels. The analysis conclusively shows thujone concentrations have been grossly over-estimated in the past. http://www.thujone.info/thujone-absinthe-39 Nephrite (talk) 05:33, 19 April 2008 (UTC)[reply]

A good example is the writing of Oscar Wilde where after a long night of Absinthe drinking he saw the waiter water the floor and flowers grew up out of the tile. The next day he realized he had been watching the Waiter mop the floor and put the chairs on the table. There are decades of stories like this from more than 50 public figures. I personally have experienced these effects from Absinthe. Perhaps it is the combination of herbs or a different compound that is responsible but to say that there are no effects stronger than Tequila is absurd. Perhaps we should just create an article reference all of the stories from the literature. I could add about a dozen in an hour or so worths of documenting and I am not a big absinthe fan. I am sure others would have no problems coming up with more. —Preceding unsigned comment added by Colinsk (talk • contribs) 22:11, 13 November 2008 (UTC)[reply]

What are these stories? The Oscar wilde example is a great example of how absinthe's "effects" have grown over the years. The tale was never actually said by Wilde himself but occurs in a 1949 book. You can read more here, http://www.oxygenee.com/absinthe-effect/secondaries.html Every effects story I've read so far seems to be misinterpreted over the years to create the "effect." Not to mention as pointed out an effect means little about thujone. -- Ari (talk) 03:31, 14 November 2008 (UTC)[reply]

"abnormally" or "erroneously" ???

The article includes this passage":

"GC-MS testing is important in this capacity, because gas chromatography alone may record an abnormally high reading of thujone because of other chemicals present.[8] Through these tests it has become evident absinthe contains very little thujone."

Is "abnormally" what is meant, or is it rather "erroneously" ? I suspect it is the latter. This seemingly careless wording radically changes the meaning of this crucial passage.Daqu 02:18, 13 November 2007 (UTC)[reply]

While it could be abnormal, it is most certainly erroneous (the word that should be used) good catch. -- Ari 03:06, 13 November 2007 (UTC)[reply]

Recent Erowid add

I wouldn't consider a trip report a valid report, nor does it specifically isolate thujone. -- Ari (talk) 06:52, 5 December 2007 (UTC)[reply]

Well no, one trip report from erowid is hardly conclusive. But there are 54 trip reports on the erowid site concerning the smoking of wormwood or wormwood extract, almost all of which report some kind of effects. And while thujone is not isolated, it is the main component of an alcoholic extract of wormwood and the only one which is known to produce pharmacological effects on the brain. Besides the journal article cited where they administered pure thujone to people obviously produced some kind of effects so its clear that thujone is psychoactive in some way, although certainly not hallucinogenic. Meodipt (talk) 06:58, 5 December 2007 (UTC)[reply]

This isn't the wormwood page. Without controls they remain interesting but anecdotal reports, wormwood extract is sometimes combined with other substances in those reports as well. "The only one known to produce pharmacological effects" because many of the other compounds have never been tested. Sure it does cause effects, I just wouldn't accept erowid trip reports as evidence of said effects. -- Ari (talk) 07:05, 5 December 2007 (UTC)[reply]

Point taken. I have added a reference from a scientific journal where they describe the use of the essentail oil from a different thujone-containing plant in herbal medicine, including CNS side effects such as anxiety, sleeplessness and headache. This essential oil contains thujone as the major component and only active ingredient, and the CNS side effects confirm that thujone has some kind of CNS effects (probably from GABA antagonist effects if it causes anxiety and sleeplessness) Meodipt (talk) 07:09, 5 December 2007 (UTC)[reply]

I like that add, thujone rarely gets any interest or study outside wormwood it seems. -- Ari (talk) 07:21, 5 December 2007 (UTC)[reply]

Structure

One isomer is depicted but not labeled.

Pgpotvin (talk) 23:48, 8 December 2007 (UTC)[reply]

I looked into this, but could not find many good references. I searched IUCr journals and SciFinder for crystal structures but didn't find any.

The one place I did find a referenced structure was the CRC Handbook, which gives the structure as

Here are the structures as drawn by NEUROtiker - unfortunately, no references are given:

skeletal formula
name	alpha-(+)-thujone	alpha-(−)-thujone	beta-(+)-thujone	beta-(−)-thujone

Wrong pictures. See

I hope you got them right! I added them to article. No sense (IMHO) putting only two structures in when all four fit as well and better explicate what you're trying to say.71.31.147.72 (talk) 21:47, 31 January 2012 (UTC)[reply]

Weird Regulations

I find it odd that the European Union's maximum allowed levels of thujone are so low. Assuming that the mean lethal dose/body weight in humans is the same as that in mice, you would need to drink 85% of your own body weight in "bitters" or eat 120% of your body weight in "food prepared with sage" in order to get to the 0% fatality level that was confirmed in the study.

That would mean if you weigh 75 kg, and you ate 90 kg of sage-containing foods, you'd still be at the 0% fatality level (and so would not die) even if the food contained the maximum levels the EU will allow. You'd probably die of stomach rupture long before you even come close to dying of thujone.

Weird. —Preceding unsigned comment added by 70.99.104.234 (talk) 01:51, 23 December 2008 (UTC)[reply]

Probably someone in European union made tests and ate 90kg of food containing that amount of thujone while weighting 75kg and died... that is why it must be so low... —Preceding unsigned comment added by 80.238.99.54 (talk) 23:12, 29 March 2009 (UTC)[reply]
