- Nicotine is the main psychoactive component of tobacco, and thus one of the most widely used and abused drugs in the world. In this video, I discuss how nicotine interacts with nicotinic acetylcholine receptors in the central and peripheral nervous systems to produce its behavioral effects.
TRANSCRIPT:
Welcome to 2-minute neuroscience, where I explain neuroscience topics in 2 minutes or less. In this installment I will discuss nicotine.
Nicotine is the main psychoactive component of tobacco. It primarily exerts its effects by activating, or acting as an agonist, at certain receptors for the neurotransmitter acetylcholine. These receptors, known as nicotinic acetylcholine receptors, are found throughout the central and peripheral nervous systems. When nicotine binds to nicotinic acetylcholine receptors, it typically causes depolarization of the neuron they are found on and the resultant release of a variety of neurotransmitters.
Nicotine’s action at acetylcholine receptors is thought to be the starting point for the drug’s behavioral effects, but exactly how it produces these effects is not completely clear. Nicotine’s rewarding and addictive qualities are thought to be linked to its ability to cause increased dopamine levels in areas like the nucleus accumbens. Nicotine also increases acetylcholine release, which might contribute to the enhanced attention and cognitive function associated with its use. And its ability to increase norepinephrine activity might contribute to the heightened arousal caused by the drug. In all of these effects, however, it’s likely multiple neurotransmitter systems are involved.
Nicotine also acts on nicotinic acetylcholine receptors in the peripheral nervous system, where it can lead to increased sympathetic nervous system activity like an elevated heart rate and blood pressure. It also causes the increased release of catecholamines like epinephrine from the adrenal glands, which can further enhance this sympathetic activity.
Although nicotine first activates nicotinic acetylcholine receptors, it subsequently causes the receptors to become desensitized, or less responsive, increasing tolerance to repeated uses of the drug. As more receptors become desensitized, the brain tends to up-regulate, or add more, acetylcholine receptors. These increased receptor numbers might play a role in the withdrawal and craving that occurs when nicotine administration is ended.

I really appreciate how you just give the facts, I love learning about the affects of drugs on the brain but so many videos are packed with bias. Like, even if I agree that you shouldn’t do heroine I still wanna know how it works😂
I hate when people give their whole life story 😂😂 just give us the info!!
we have the same brain
Couldn’t agree more. Just show me the science and leave all the rhetoric please. Same thing when trying to learn functions of government. No one just tells you the functions, they have to throw in their pseudophilosophy with it

Great Video! Sorry for the intrusion, I would appreciate your opinion. Have you heard about - Senarper Wordless Supremacy (probably on Google)? It is an awesome one of a kind product for stop aging and improve your life minus the hard work. Ive heard some unbelievable things about it and my work colleague finally got excellent results with it.
Makes me feel spacey and dizzy 🥴
Does everyone in the beginning. That's the very reason we kept doing it in the beginning. Unfortunately that doesn't last forever and by the time you no longer get that effect you're hooked. I been trying to quit nicotine for over a year after smoking/vaping for almost 30 years. It's not easy to stop. And just for reference, I'm also an ex opiate junky. And as suck I can say with full confidence that quiting heroin and other opiates (clean now from that stuff almost 9 years) quiting those substances was far easier than quitting nicotine.
An interesting fact about nicotine though is it's actually not that harmful. What's harmful is the way you ingest it. Cigarettes are definitely bad. Vaping is debatable because we don't really know how harmful it could be because it hasn't been around long enough, but I'm sure it's probably much safer than cigarettes. I keep bouncing back and forth between the two. Actually quit smoking for over a year with vaping and then for some dumb reason went back because I started hanging out with smokers again.
Long story short, be careful messing with this stuff. It didn't destroy my life near as much as opiates, but it's definitely hard to stop once you been doing it for awhile, even if you really want to.
I'm not gonna tell you what to do because we all have to make those decisions for ourselves. But I did want to put a warning out there from someone who knows and is still dealing with it.

It's bizarre that our society strongly discourages relatively safe methods of nicotine usage, while treating TV/media consumption, fast food, soda, sexual hookups, etc as things that people are going to inevitably do. All those behaviors are more destructive than vaping or smokeless tobacco use. Meanwhile, nicotine boosts mental alertness, testosterone, and work drive. Our ancestors in the 1500s loved tobacco so much that it spread across the globe, and many geniuses who contributed to our modern world, like Isaac Newton or the US founding fathers, were regular users. Using tobacco can be an intelligent and deliberate choice.

Nicotine has been demonized. In its raw form, it is harmless at the right dosages. People like to associate nicotine with tobacco use that contains additives and carcinogens that WILL cause negative effects.

Thanks for the precise and concise explanation!
I think the process and pain/discomfort/anxiety of withdrawal is the death throws of a dying receptor. It is programmed to survive by all means
The thing is, its so addictive because it works so well for whatever situation that prompted it. Depression? Trauma? Breakup? Impossible task? Self medicating ADHD? It will help you, and will continue to do so for a few days, making EVERY situation better, good, bad doesn't matter. But then one day it doesn't.
It only works once.
But once is all it takes.
The horrible part is, since gene promotion/upregulation has brought about so many receptors, is that when an addict relapses, it is often stronger in effect.
Best case scenario: Your receptors in your stomach go top-fuel drag and give you an experience akin to that scene from the exorcist. You are now disgusted by the mere thought of nicotine, for now at least. You have a 30% chance of you actually stopping in response to this.
Worst: That narrow "theraputic" index is bullseyed, and it's bliss, even better than that first time, for about 30 mins. Finishing that assignment (You should really start it btw) is worse than whatever trauma started you on nicotine. You chase that same glorious buzz for the next 4 weeks until you repeat the cycle.
As someone who has used nicotine since they where 13 (and I was one of the first few in school who started that early, most didn't start until they where 17) this was rather informative and frankly I'd rather this be presented in school instead of what we got the whole time. I've made some bad choices and weed helped me get away from long-term nicotine use. That said nicotine is like caffeine for me
Weed is literally worse than nicotine.

I started nicotine (I don't smoke cigarettes) when I had a stressful week with my assistant manager. He was not qualified for the job and my boss chose to hire him after chatting with him at a bar.
I started using it so much and made me feel better for a bit. I am still doing it and it has been one ride.

As someone that never smoked in my life, last year I tried nicotine pouched, and I liked the effect it gave me, I took more to get that high, now 11 months after I don't get the high at all, but I'm addicted, when I don't get it I get a crazy headache (like a concussion type migraine), one of there nicotine pouches is equivalent to 20 cigarettes in terms of nicotine, and I take around 10/14 a day, srsly don't start
It was around the same with me, try making time frames to when you can put your next one in, and get these time frames away from each other with time, this means you taking less pouches a day, I got off this way, might help man
man i smoke pipe, weed, cigars use pouches and snuff. Im not addicted to any of that and its not even difficult to stay clean for 2 or 4 years. But 10 pouches are you crazy i use like 5 a month. I am doing this for more then 15 years and recently i buy only my 4 box.
10-14 a day that is almost box a day. Also you can get addicted to almost anything, its not the substance but dosage. But congratulation you developed a nicotine addiction, you make your body super sensitive so if you abstinence for several years 1-2 pouches and you are back were you started
I used to smoke a pack of cigs a day while dipping a half can a day. Then I quit smoking and was dipping a can a day lol. I quit dipping for like a year and then I tried it again and felt absolutely no buzz.
I wonder how long does the nicotinic acetylcholine receptors to down regulate back to their original levels, and become "normal", if that even is possible.
If someone knows studies done on this topic let me know. Yes I'm also aware that it depends on many factors like how long the use has been, dosage etc.
Just wondering because I quit using dip about a year ago after about 7 years of continious use, and have noticed still cravings sometimes.
cravings are different from dependence.
It took me several years after deciding to quit smoking weed to actually not want it anymore.
I started with one year of cold turkey. Not smoking any weed, only allowing regular cigarettes. I grew my own marihuana as an incentive to stay sober until I had my own harvest to smoke. I wasn't completely sober that year, I drank alcohol and had the occasional joint at parties, but other than that I was doing really well.
Then, when the harvest was ready, I had an ounce that I smoked up pretty quickly. My "normal" usage before the cold turkey was daily, so I'd always smoke a joint before going to bed for about four years. With my harvest, I got back to the old habit, even though I didn't want to. I took it as a period to profoundly appreciate that feeling of being stoned and being grateful of having something to smoke that I cultivated myself. After that, I decided it was time to turn the page and stop smoking weed for good.
That took about two years of going on and off, with which I mean I struggled significantly being sober. I tried to get my kicks from other things, like sex, adrenaline rushes. Looking back on it, I got into some borderline sociopathic behavior. My environment took it pretty well tho, because they knew I was trying to get rid of this addiction.
I think I've been fine with being sober for about 15 months now (had my last ciggy in Summer 2021). I haven't smoked nor craved weed or cigarettes for about a year now and my mates got mad at me for not wanting to go to the coffeeshop last time we went to Amsterdam lol.
I decided to go cold turkey in 2014, so that's almost 8 years for me to get rid of it. That's kinda crazy. Sorry for the amazement, but I never thought out how long this journey has been until I wrote this comment down lol
It takes 90 Days to return to baseline.
Another great video my friend! Might I suggest making the video 30 seconds longer to account for the intro? That was it's' 2 minutes of *_information_*
Thanks again for these videos
I have never subscribed to a channel faster
I read that nicotine, somewhat enhanced by the low level radioactivity of tobacco activates once dormant vestigial neurons. Which is part of why nicotine addiction is so difficult to overcome. While most drugs act as agonists on existing neurons and other less potent agonists can used to satiate cravings, the neural receptors acted on by nicotine only respond to nicotine since the body no longer processes the natural agonists that act on those neurons.
Useful information thank you...👑🔥👑😎💰👍💰👍🔔👑🙏
literally the only video you can find that explains what nicotine actually does, as opposed to just 'smoking bad, don't do it'.
Thank you all i need to know
Watching this with a fat dip in😂
You are so cool.
Disgusting!! When your lip and tongue turns black from cancer, I'm sure you won't be laughing then.
Dont agonists cause a downregulation? Because if more Nicotinic Receptors are made, theres more receptors for Nicotine to bind to.
Yes, typically. Nicotine is something of an anomaly. When it activates acetylcholine receptors, it also causes desensitization of the receptor (i.e. the receptor becomes less- or non-responsive). It's thought that this desensitization is associated with an increase in the number of nicotinic acetylcholine receptors, although the exact mechanism of this still isn't fully understood.
Neuroscientifically Challenged The desensitization is why I get really buzzed only during the morning?
@@sylocin Yes, it's thought that receptors become desensitized during the day due to regular smoking, which promotes short-term tolerance. But they regain sensitivity overnight due to abstinence from nicotine.
In truth, cigarettes are designed to last for the length of time it takes for your receptors to desensitize. At that point, it takes roughly 45 minutes for them to resensitize, during which time the receptors are not responsive. As your body craves nicotine, it upregulates to compensate for the lack of nicotine, but this only causes you to need more and intensifies your withdrawal craving.
@@Neuroscientificallychallenged I thought having more receptors would mean the postsynaptic neuron becomes more sensitive? And conversely, receptor downregulation causes desensitization?

dopamine from what i understand is what makes you motivated, ready to move, and energetic when you have sufficent levels of it. ive used amphetamine (prescribed for adhd, highly dopaminergic) of course caffeine, and nicotine and amphetamine has the strongest boost in motivation and energy but nicotine is less strong then caffeine for me, even though nicotine is supposed to have more addictive potential then caffeine. we all have different chemistry i guess, ive also quit nicotine suddenly before and it is not nearly as difficult as quitting caffeine

Hello there. What exactly gets desensitized? Is it the receptors themselves, and in what way? Do they get thicker or something so the electricity becomes less intense? And how does this go in hand with there being more receptors?
My notes:
Nicotinic Acetylcholine receptors - throughout the whole NS
Nicotine - agonist, changes in the polarity of the receptor, increase in acetylcholine - enhanced cognition and attention, noradrenaline - stimulation and arousal
PNS - increase in sympathetic NS activity, secretion of catecholamines - adrenaline from adrenal glands
desensitize -> more receptors
Based.
great drug, highly suggest using it 👍
When I first started using nicotine years ago I could take 2 or 3 milligrams and I felt great, zero tolerance but didn't get sick at all. Now I can't even handle a milligram and I'll take like 0.25 milligrams and that will have a good effect on me but it's not like it was when I was able to take more.
how can i stop taking?

Notice that he says “might” in almost every explanation so these “might” differ from person to person.
A Harvard study has determined that nicotine is NOT addictive. Rather it is a separate chemical that the tobacco industry adds to their cigarettes that causes addiction.
Shouldn’t receptors eventually be downregulated because of too much signals?

Heroin affects the brain similarly by creating more receptors to accommodate the flood of dopamine. Withdrawal is completely mental but can be felt in the entire body.

what I need to know is: can you ever go back to normal if your acetylcholine receptors have become desensitized / more have been added? Will they reset themselves if the abuse of nicotine stops?
Nope, permanent brain chemistry changes. Enjoy your new homeostasis

Any trooth to Tucker's Nicatine frees your mind where as THC is basically the imperious curse from Harry Potter argument?
Does this apply to smokeless tobacco also?
Yes---same drug, different method of delivery.
why nicotine in low concetration stimulate the receptor and in high concetration block the receptor please i want clear answer
its the body response to all over stimulation. The body constantly trying to achieve chemical balance if body "loose" this ability well that is Parkinsons disease, epilepsy and seizures
In short term you basically depleted the receptor chemicals for communication, in long term you burnt out/damage the receptor. That is also why body create more and the withdrawal symptoms are also part of neurons repair.
Also clear answers are in mathematics (most of the time) in biology there is no clear or simple answer

I have recently developed a slight left sided peripheral vision loss due to smoking nicotine vapes. Do you think this damage is permanent or will it restore over time?
has it restored?
i once have something similar. It was cause by extreme blood pressure pushing against optic nerve. But it was when i was deadlifting 385 pounds and this vision loss lasted only several minutes. Nicotine does increase blood pressure it will be good advice to visit doctor if its everything ok and you dont need medication for high blood pressure. If you are overweight have sedentary/inactive lifestyle and consume exes of caffeine.
The other option is brain tumor.
To answer directly its permanent damage if it dont go away in few hours. But it will heal and restore some of the vision but brain will fill out the gap if it is not too big. I would ask why you dont go to see doctor once you notice that but i think you are a american.
It has gotten better, and my brain has adapted. But not restored 100%

Hi can you please answer... could nicotine help with muscle memory? like using nicotine to improve nervous system and become a better guitar player for example? same with ritalin caffeine etc? plz thanks
I don't understand, if there's more nicotinic receptors the more they smoke, then as they smoke, over time they will receive a larger dopamine rush per smoke right? But the opposite happens. In reality, they get tolerance and get less dopamine per smoke.
My question is can zyn nicotine salt pouches cause brain damage?
No they're safe

Good vid! Very factual. But I'm not smart enough to be able to use this info in a way that helps me decide if nicotine is harmful. My understanding (right or wrong) is that nicotine is comparable to caffeine as far as negative health effects. Anybody wanna comment?
If you are younger than 25, don't use! Even a brief exposure can alter your brain development. If you get addicted (use every day, once a week, dependent on it in some way), the damage has occured, resulting in impaired attention and ability to learn, memory problems too and lower impulse. Additional damage can occur as nixotine products increase blood pressure, which can impair blood circulation around the brain, causing brain damage on its own.
@@exposingreality6391 I would be very curious to see studies for this. Do you mind sharing the evidence for your claims? Furthermore, what do you mean with: "a brief exposure can alter your brain development?". A brief exposure to daylight in the morning, or briefly falling asleep, can also alter my brain development, no?

Its interesting to me how the withdrawal of nicotine can be compared to alcohol or benzodiazepine withdrawal because then the brain causes withdrawal due to the brain having to many GABA receptors.
Watching this while I'm vaping
Anyone else vaping rn?
Say hypothetically you stop consuming nicotine, would the additional acetylcholine receptors your body created be removed?
Body gladly make more stuff but there are very few mechanism that break down stuff. After time there will be some reduction but not by much. Also in any prolong use of any drug or substance you train your body so even after decades of abstinence and threshold decrease after few doses your tolerance is right back.
Just like with alcohol tolerance even after years of abstinence few weekend and you again can drink the amount like nothing happened.
So this goes against what Dr. Ardis is saying and that nicotine can help people with long covid. More studies are definitely needed

College Students wya 😌
Me too :(
dropped out of college wya
I started using tobacco snus for a few months, each pouch had 50mg of nicotine in it, and I used about 8 a day. Thats 400mg, which is about 40 cigarettes a day.
I really enjoyed them and definitely prefer them to smoking, the burn sensation and the minty crystal taste which turned into a delicious tobacco taste. Stuffing one in the morning was fantastic and went really well with alcohol and tea/coffee. Stuffing one in the evening after eating was brilliant as well.
Since I live in The UK, it’s really hard to get and only this one shop sold them, which they ran out so I quit. Glad I did because I was getting sick of the increased heart rate (it’s a stimulant)
Wow. So nicotine adds choline receptors. Interesting. So is it possible choline supplements could curb the withdrawal?
Also I've also gotten a lot more interested in learning stuff over the years. Is it possible that my nicotine addiction and added choline receptors are partially responsible for this? I know choline and nicotine are considered to be "smart drugs". 👈 Notice the parentheses? I'm not saying it's smart to ingest nicotine, it's just a regularly used term for a group of supplements/drugs.
After messing around with nicotine after being off it for a very long time, I tried to use it more as a smart (vyvanse) it’s not very effective, it’s great at headaches and provides better focus (less zoning out) but a bit too stimulating. Coffee seems to be a better smart drug, paired with working out and a healthy diet can improve the effects of nic and coffee but idk if the nic is worth it. Also my legs hurt when i use nicotine and doesn’t when I use coffee. Both are drugs but what would make us smarter would be by doing things and being active with our minds. Sitting around and being lazy does not make any medication/supplement/diet effective
@@JZGreengo Good anecdote. Reminds me of how I reflect on drug use myself. I've been experimenting with nicotine gum as a potential nootropic of sorts. It seems like it could best fit in as a comparatively less harmful "chill out" drug as it mostly just makes me a bit light headed and very mildly euphoric. The addictive potential concerns me, although almost all reported long term negative consequences seem to be from getting it through smoking specifically. I was hoping to get more of the commonly reported focus boost, but it seems to do a bit of the opposite for me. Cheers to better health.
No bullshit no propaganda to quit smoking pure science just facts thank you
I don’t notice anything from nicotine except lightheadedness and nausea

Nicotine is fun but it's an expensive addiction and kinda pointless after a few months.. Also FUCK CIGGIES
Does nicotine affect learning?
like in long term or when high. I think long term no but not sure when high on nicotine. If it impair the function of amygdala and hippocampus then yes.
