Chemistry

[edit]

The info-box doesn't identify the chiral center, nor is there any indication that it is, indeed chiral. The chemistry section has one paragraph with (+)-, (-)- nomenclature and the next with the preferred (R)-, (S)- nomenclature. Could someone clean this up? The chemistry section also describes it as a "colorless to yellow-brown, oily liquid" which is just awful. I suspect, it is, when pure, colorless, while commercial material undoubtedly contains contaminants (which, I presume, give it various discoloration). (Amines are notoriously difficult to keep pure, aromatic nitrogen compounds are photosensitive, so it isn't surprising that commercial products are off-color, even if originally pure and colorless.) The info-box claims a few physical properties. I question this. First because it isn't likely that the racemic mixture has the same physical properties as the pure (R) or (S) compounds, and second because of the enormous temperature range in which it is -supposedly- a liquid. I question the liquid range is 326 degrees C (586 F), and I'd expect the racemate to have slightly different range. Finally, it is really strange and atypical that the info-box doesn't have the IUPAC systematic name (or names depending on whether property belongs to a specific isomer or a blend of the isomers. It would be notable, if true, for the natural product to be racemic. Is this claim verified or does it rely on crude analysis without a chain of custody to show no tautomerization/racemization didn't occur during collection and analysis?174.130.71.156 (talk) 12:05, 27 March 2023 (UTC)[reply]

Nicotine itself is not nearly as addictive as thought.

[edit]

Nicotine does not produce significant withdrawals on its own (such as when people consume nicotine through vaporizers) to most people except those extremely liable for physical dependency. All sources that state that nicotine itself is highly addictive point back to the same incredibly flawed information, such as the Surgeon General's report from 1988. They claimed that nicotine was the primary addictive component because tobacco smokers experience withdrawals, and nicotine was the chemical that produced the high. This is, in many cases, the _ONLY_ citation you're going to find, or things point back to it that have also not shown isolated nicotine to be highly addictive.

The addictive qualities of _tobacco_ are caused by MAOIs and, in cigarettes, acetaldehyde (not added directly but formed when heated) and other additives. While Nicotine is dopaminergic, it's not incredibly so, nowhere near enough to be considered heavily addictive. The MAOIs on their own would already be addictive, but reinforce the nicotine as well.

If you aren't already liable to be addicted to nicotine, it is about on-par with caffeine in terms of addictive qualities. Yukenk (talk) 22:08, 23 September 2023 (UTC)[reply]

I apologise I am drunk and was reading through the page, immediately made an account to write this, without reading the guidelines. Yukenk (talk) 22:09, 23 September 2023 (UTC)[reply]

Good article nomination

[edit]

@Seppi333@QuackGuru@HLHJ. Is it okay if I nominate this article as a GA? Nagol0929 (talk) 13:21, 15 November 2023 (UTC)[reply]

Nagol0929, it would need a lot of work. It's not very readable, the selection of information is odd and liable to be very controversial, and there are gaps. I'm not unwilling to help, but it would be a couple weeks before I could do much work on it. HLHJ (talk) 18:47, 21 November 2023 (UTC)[reply]
This would be my first big content creation. Would you be willing to coach me? Nagol0929 (talk) 03:26, 13 December 2023 (UTC)[reply]
I'd strongly suggest another topic for your first big content creation. This one will be controversial and generally a pain. Due to WP:systemic bias, there are plenty of important topics with no content. That said, I find content creation quite rewarding, and I'd encourage you to get into it. I'd be happy to help if you want coaching. HLHJ (talk) 00:16, 15 December 2023 (UTC)[reply]

Clarify that genotoxicity is only shown in vitro

[edit]

The first sentence of Genotoxicity should probably read "Nicotine causes DNA damage in several types of human cells in vitro ..."

From the 3 sources under Adverse Effects/Genotoxicity:

- Introduction mentions "freshly isolated single cells of human nasal epithelia and a permanent human bronchial cell line": https://www.sciencedirect.com/science/article/abs/pii/S0378427411015578

- Title mentions in vitro: https://pubmed.ncbi.nlm.nih.gov/24698733/

- Abstract mentions in vitro: https://pubmed.ncbi.nlm.nih.gov/23200805/ Nathan Franke (talk) 05:06, 31 October 2024 (UTC)[reply]
