shocked Posted February 14, 2012 Author Share Posted February 14, 2012 Drugs, Science and Politics: a recipe for disaster? Lecture from Professor David Nutt on 18 January 2012. http://www.ed.ac.uk/schools-departments/psychiatry/lecture-videos/drugs-science-politics In this lecture he discusses the risks associated with drug use, and how the relative risks influence drug classification and national drug policy. shocked edit This informative and often amusing talk has many highlights. For me - Dave’s reference to “defence of necessity” is most heartening and liberating. Quote Link to comment Share on other sites More sharing options...

Purple Posted February 18, 2012 Share Posted February 18, 2012 In French about a French Alzheimer research group on non hallucinogenic psilocybin for Alzheimer http://www.lemonde.fr/planete/article/2011/10/28/une-rehabilitation-difficile_15... Anybody know how to get an english translation of this page? Ron Enhanced Google Translate translation of: http://www.lemonde.fr/planete/article/2011/10/28/une-rehabilitation-difficile_1595139_3244.html Hallucinogenic mushrooms: a difficult rehabilitation | 28.10.11 | 4:52 p.m. • Updated 24.01.12 | 3:47 p.m. Roland Griffiths is not the only one to work for the rehabilitation of psilocybin. But teams looking to test their medical effects are rare, despite initial success. In 2006, Francisco Moreno and colleagues at the University of Arizona have published the results of a pilot study that showed a significant reduction in OCD psilocybin. But this trial included only nine subjects, and Francisco Moreno said to have been there to end "because of the cost and difficulty in finding funding for such research. " Still in 2006, a team of Harvard published the results of the effect of the molecule on cluster headaches, a form of migraine among the most painful. Of 26 psilocybin users, 22 had reported their current CH attack being stopped.. A large proportion indicated that this decision marked the end of these migraines or an extension of the period of remission, whereas the doses used were too low to cause hallucinogenic effects. At Centre for Neuroscience Zurich, Franz Vollenweider notes ''a little come back of psilocybin, not a great return''. He resumed the study in the institute where the first doses of LSD were tested. Compared with ketamine, an anesthetic with psychotropic properties and that improves mood, psilocybin appears promising to this researcher: "It has fewer side effects. But it is more difficult to study because it taboo and runs into more stringent regulatory barriers" So he will be testing both compounds on patients with severe depression. Eliminate the effects hallucinogenic He points out that small pharmaceutical companies have shown signs of interest not for psilocybin itself, but for possible derivatives that could be extracted from it. In fact, the appeal for its biological action may be revived - indirectly - to the extent where it seems to act on brain pathways important to fight against impairment of memory, as in Alzheimer's disease. Thus, at the University of Caen, the team of Valerie Collot, professor of pharmacognosy (the study of medicines derived from animal or vegetable), is working on the development of analogs of psilocybin that would allow to set free from the hallucinogenic effects while improving memory. She says: "Our interest goes back in 2009, when an article by a Japanese team had shown that activation of certain serotonin receptors enhanced the memory." It so happens that these receptors, type 5-HT2C , have a strong affinity with psilocybin. The art of the Lower Normandy team will now be to synthesize compounds that mimic this affinity without presenting yet another one for the 5-HT2A receptor, which appears to be involved in the "a little more embarrassing." hallucinogenic effects. This type of chemistry is complex, because you have to find ligands both potent and selective, which do not interfere with other, and numerous, serotonin receptors,. "In mice, early results are quite encouraging, says the researcher. But to pass to humans, it will take several years of study. " Test compounds are not derived from psilocybin. "We synthesize them in five or six steps, then we optimize them." Is there a risk of falling on a hallucinogenic compound? "It is always possible, but I have not seen any particular effects on people who handle them. "All operations are done under vacuumed hood, so for one to expose oneself to the products like didn't hesitate to do Albert Hofmann - the creator of LSD, who also isolated psilocybin in the late 1950s - it should be wanting . "Early in my career I have experienced supervisors who tasted their prod ucts," said Valerie Collot. But she assures this "is ancient history."

Bonkers Posted February 29, 2012 Share Posted February 29, 2012 Thanks for the translation, Purp. Sorry for the delay - I've been on a time-out. Wow! That a non-hallucinogenic derivative of Psilocybin could prove effective against the memory loss of Alzheimer's leads me to believe that maybe a whole bunch of researchers are investigating the properties of non-hallucinogenic derivatives of psychedelic drugs. We may end up with several BOL-like compounds to choose from. This could be a good thing from several standpoints, not least of which is our current understanding that drugs found beneficial for one CH patient don't work for another.

Purple Posted February 29, 2012 Share Posted February 29, 2012 ...Alzheimer's leads me to believe that maybe a whole bunch of researchers are investigating the properties of non-hallucinogenic derivatives of psychedelic drugs Yes, well maybe not ''are'', but ''will be'', since Alzheimer affects many people. My guess is actually that psychedelics can probably heal many ills but there is a big wall to jump: Bad news is Le Monde removed this article from their Web site, and any search for it now leads to a few esoteric sites... and here. Le Monde's search engine returns 0 result when searching ''psilocybine'' ... they had at least 2 articles just last week.:-( Quote Link to comment Share on other sites More sharing options...

Ricardo Posted February 29, 2012 Share Posted February 29, 2012 Although I have never heard of a non-hallucinogenic analog of Psilocybin, there are at least 2 pretty well known analogs, CEY-19 and CZ-74. Seems like the biggest difference is the length of the trip--these analogs seem to last a bit shorter, more like 3-6 hours. If we can ever convince the feds to let us have a real psychedelic substance (very doubtful)--these are what I would put my money on. http://www.erowid.org/chemicals/4_acetoxy_det/4_acetoxy_det_primer.shtml -Ricardo Quote Link to comment Share on other sites More sharing options...

During such headaches, they show an increase in hypothalamic activity to date has only been ameliorated by deep brain stimulation. However,” he concludes, “when administered psilocybin, they display a decrease in hypothalamic activity and a corresponding suspension of cluster headaches.” Carhart-Harris. shocked Quote Link to comment Share on other sites More sharing options...
