external links

I deleted the THC-link because I think this website is not a reliable resource for medical information, irrespective of which professor wrote the information. I think well-known, peer-reviewed sources should be the standard. Please discuss here if you disagree.--Steven Fruitsmaak | Talk 05:40, 24 July 2006 (UTC)[reply]

I do not agree with your philosofy at all. The information on Cannabinoids that I linked to is from one of the world's most outstanding researchers on cannabinoids and gives a ton more information on cannabinoids(Dr. Robert J. Melamede Ph.D. Chairman of the Biology Department of the University of Colorado: Conducting Scientific research on Cannabinoids), and how they work in the body that that other external link which only mentions the word in a list of other words.

Also, the website, and page, that this information is on; http://www.thc-ministry.net/cannabisinfo.htm is totally non profit, non commercial and has no ads or sells anything whatsoever and contains lots more scientific facts and information.

I also do not agree at all with your reasoning as this being spam because of the fact, as you state it, that I belong to the organisation, this would mean that when experts in their field who work for a university would be spamming when they refer to relevant information on their university's website.

--Ferre 00:56, 26 July 2006 (UTC)[reply]

1) I do not contest that this professor is respectable (although he has only 2 articles on PubMed related to cannabis? so maybe you're overstating just a bit).

2) I think a website that states "It is our opinion that cannabis is the original sacrament of Hebrew, Christian, Muslim, Hindu, Shinto, Buddhist, Rasta and more, and fulfills the prophesies to feed all our hungers." probably doesn't have high scientific standards, and is not notable as a reference on this subject.

3) Any professor can make a simple mistake, that's why peer-review was invented. I'm not saying the info is wrong or not interesting, on the contrary! But I'm sure other references like OMIM and eMedicine are superior.

4) Since it indeed gives a ton more information, you might consider moving this ton of info into the article, instead of providing a link. I'll be the first to applaud this, and in fact if I find some time and can find references for those statements, I will!

5) I think it is always dangerous to provide info about an organisation to which you belong yourself, because of the difficulty not being biased. This does not mean that info on certain websites can be trusted, but in this case I think the link doesn't belong because, as I argued before, this website is not a reliable resource for medical information. I believe this is so because (i) the website doesn't have a neutral point of view (ii) it is not a well-known, peer-reviewed resource. --Steven Fruitsmaak | Talk 10:57, 27 July 2006 (UTC)[reply]

Changes

A reference for CB2 and intestine was inserted
The Nature reference is now in the proper format
The phrase 'need for selective ligands' was deleted as there are plenty of CB2-selective ligands now
The heading pharmakokinetics was changed to Signaling as pharmakokinetics are something else.
A reference for a new cannabinoid receptor was included
Several possible for cannabinoid agonists and antagonists were added

technical template

I feel I have a pretty good grasp on general neuropharmacology but a lot of the questions I had about cannabinoid recepters were unanswered for me, or I felt might have been available if some of the wording was more explanatory. Some sentences just made bland technical assertions without any context, such as "For instance, in the liver, activation of the CB1 receptor is known to increase de novo lipogenesis,[6]" -- please compare this with a much better sentence (though still not perfect): "They also displayed suppressed locomotor activity as well as hypoalgesia (decreased pain sensitivity)." 174.99.120.127 (talk) 23:22, 18 August 2009 (UTC)[reply]

So go ahead and fix it! :) -- œ ^™ 03:13, 19 August 2009 (UTC)[reply]

Scope of article

The scope of this article is wider than human cannabinoid receptors (see HomoloGene: 7273 and HomoloGene: 1389). IMHO this article falls more within the scope of WP:MCB / WP:SCIRS than WP:MED / WP:MEDRS. As long as animal studies are clearly marked as such and no medical claims are being made, they should be allowed in this article. Boghog (talk) 07:06, 14 December 2013 (UTC)[reply]

I'm fine with restoring them if you think its the better option, though I think it'd be preferable to group all the animal studies in their own section, sort of like TAAR#Animal TAAR complement. My only concern is that uninformed readers will erroneously assume that animal receptors are representative of those in humans if there's no distinction.

Physiology section needs work

While I'm sure the content of the Physiology section is scientifically accurate, Wikipedia is not a scientific journal. Accuracy is important but so is communication. The real purpose of a general Encyclopedia such as Wikipedia is to elucidate a subject. I would like to understand the Physiology of cannabinoid receptors and I'm not stupid, but I am a lay person and could use just a bit more of a layman's explanation. Thanks!

Opening sentence, specifically "cannabinoid receptor system"

The opening line: "Cannabinoid receptors are part of the cannabinoid receptor system[...]" seems redundant, maybe even circular. The way this is written, I'd think cannabinoid receptors are a subset of cannabinoid receptor systems. If that's the case I'd imagine there would be an article specifically describing the system or at least some clarification in this article. "cannabinoid receptor system" is mentioned exactly once here. Sudopeople (talk) 16:38, 20 August 2014 (UTC)[reply]

Effects of pre-natal cannabis use

Currently worded as:

Prenatal cannabis exposure (PCE) has been shown to perturb the fetal endogenous cannabinoid signaling system. This pertubation has not been shown to directly effect neurodevelopment nor causelifelong cognitive, behavioral, or functional abnormalities, but it may predispose offspring to abnormalities in cognition and altered emotionality from post-natal factors.^[1]. Additionally, PCE may alter the wiring of brain circuitry in foetal development and cause significant molecular modifications to neurodevelopmental programs that may lead to neurophysiological disorders and behavioural abnormalities.^[2]

Please discuss if you have any issues here with the wording before wholesale deleting. I have also moved it to the signalling section where it is relevant. Sasquatch t|c 02:08, 28 May 2019 (UTC)[reply]

History? No review, editor's synthesis

This edit on history was reverted because the content is the editor's own interpretation of history (WP:SYNTH), rather than a WP:RS review guiding what is history. All of the sources are from primary research, and are not aggregated in a review to confirm this is the actual history. Because this content addresses neurochemistry and potential neurological functions of cannabinoid receptors, a WP:MEDRS-quality systematic review is the standard needed. --Zefr (talk) 03:51, 12 August 2019 (UTC)[reply]

History of science is an encyclopedic subject and is outside the scope of WP:MEDRS. I would agree that secondary source are preferred and I will find them so that section can be restored. You need to be more careful in quoting Wikipedia polices and guidelines to those that actually apply to the given situation. Boghog (talk) 04:43, 12 August 2019 (UTC) The three of the four sources that were removed are all highly cited and the fourth is a review:[reply]

Hence in addition to citing review articles, I think the original citations should also be included. Boghog (talk) 04:57, 12 August 2019 (UTC)[reply]

I have restored the history section with secondary sources. This section expanded further based on the review articles already included (for example multiple groups cloned the receptor at about the same time). Boghog (talk) 06:02, 12 August 2019 (UTC)[reply]

The main reviews offered are Elphick (2001) and Pertwee (2006) which - although 1-2 decades out of date from now, as there are no recent reviews on the history of receptor discovery - should be the main sources on discovery of CB receptors. Elphick, Pertwee, and other authors differ on what research team and what year(s) discovery of receptors actually occurred (e.g., Lawrence, Howlett, Pfizer, Pertwee), indicating specific discussion as proposed by editor Ethel the aardvark about the St. Louis, NIH and Jerusalem groups was that editor's synthesis of events, WP:SYNTH. Neither Elphick nor Pertwee lay out the history of discovery that way, and the specificity of credit given certain labs is debatable and inconsistent, incurring WP:NOTTEXTBOOK, #6. In addition, the edit by Ethel the aardvark was carelessly written and poorly formatted, so needed trimming and rework to state the basics, as I have done with this edit. --Zefr (talk) 16:46, 14 August 2019 (UTC)[reply]

You need to more carefully read Wikipedia policies and guidelines before you quote them. Case in point is WP:NOTTEXTBOOK, #6. There was no teaching through examples going on here, just presentation of facts. All the research discoveries mentioned were highly cited, and therefore clearly notable. The problem was that there were other notable events in the history of cannabinoid receptor research that were not mentioned. So at worst, Ethel's contributions were incomplete, not wrong. The way to fix that is to add the missing notable events supported by reliable secondary sources so that the history is complete, not delete the entire contribution. Ethel's contributions were made in good faith. Your deletion was not. Boghog (talk) 17:55, 14 August 2019 (UTC)[reply]

You mistake 'number of citations' as important instead of high-quality reviews which are the encyclopedic source of choice. NOTTEXTBOOK was correctly invoked for details not related to general history - which is described differently among review authors - but for the editor (with your apparent approval) selecting isolated primary cases, needlessly highlighting academic affiliations, and missing general facts, while making a mess of syntax and format. The original revert was brought to the talk page for WP:BRD and consensus on content improvements, WP:CON. You've made no content edits. Let's allow other editors to weigh in on the history and discovery content before further changes are made to the general one highlighting reviews that I made today. --Zefr (talk) 19:43, 14 August 2019 (UTC)[reply]

The reason that secondary sources are preferred is to establish notability and reliability. A high number of citations strongly implies that the sources are both notable and reliable and this was confirmed by the secondary sources that I added. Your knee jerk reaction is to delete when in fact there is strong reason to believe that the material in question is both reliable and notable. Think before you delete. Tagging with {{Primary sources}} is far more appropriate that deleting the entire history section. "Making a mess of syntax and format" or "needlessly highlighting academic affiliations" is also no excuse for deletion. Relevant guidelines in this context are WP:AGF and WP:DONTBITE. You need to change your attitude. I will make substantial content contributions to this section this weekend when I have more time. Boghog (talk) 20:44, 14 August 2019 (UTC)[reply]

I still do not see how WP:NOTTEXTBOOK applies. The problem with the added text was not that it was teaching or was overly technical, but instead it was hyping of institutions and individuals. That can easily be fixed through copyedit. Boghog (talk) 21:05, 14 August 2019 (UTC)[reply]
