Is nicotine a nootropic?

Is nicotine a nootropic? For the last few months, I have wanted to know if nicotine affects cognitive performance and I’ve been experimenting with nicotine as a nootropic. A nootropic substance is one that improves your cognitive brain with no serious side effects,  and ideally, it is non-addictive. Loads of nootropics would not have hard science backing them up. Nicotine is among a few that have scientific literature displaying essential cognitive advantages.

Is nicotine addictive?

We can give you a short answer: yes! Cigarette smoke has well over 5,000 different ingredients; however, almost always nicotine will get all the attention because of the ‘factor that makes cigarettes addictive.

The general perception that nicotine alone causes cigarettes to be addictive is because of an influential article entitled “The Health Consequences of Smoking: Nicotine Addiction: A Report of the Surgeon General that was launched in 1988 by the U.S. Surgeon General.

The majority of smokers smoke cigarettes regularly due to their addiction to nicotine. Addiction is characterized by addiction to drugs and the use of them even in the face of adverse health effects.

A majority of smokers would like to quit smoking. Each year, approximately half of them attempt to stop smoking permanently. But, only 6-percent of those who smoke have the ability to quit within a particular calendar year. ²⁵ The majority of smokers have to try several times before they are able to quit completely. ²² Varenicline, among others, and certain antidepressants (e.g. bupropion), as well as nicotine replacement therapy, can aid in a variety of cases (see ” What are treatments for tobacco dependence?“). ²⁶

Small temporary euphoria

A brief rush of endorphins that occurs in the reward circuits in the brain can cause a small temporary euphoria when nicotine is given. This euphoria is shorter than other forms of “high” associated with other substances. But, as with other substances of abuse, nicotine raises levels of the neurotransmitter dopamine within those reward pathways, which can enhance the effect that is triggered by the use of the drug.

The repeated exposure to nicotine alters these circuits’ dopamine sensitivity and triggers changes in other brain circuits that are involved in stress, learning, and self-control. For many users of tobacco long-term, the brain changes that are triggered by continuous exposure to nicotine can lead to dependence, which can manifest as withdrawal symptoms even when smoking and a difficult time sticking to the decision to stop. 

Pharmacokinetic

The Pharmacokinetic characteristics of nicotine or the way in which it gets processed within the human body are responsible for the addictive nature of nicotine. In the event that smoke from cigarettes gets into the lung, the nicotine is absorbed swiftly through the bloodstream and is then transported rapidly to the brain such that nicotine levels are at their highest within 10 seconds after the inhalation.

However, the effects that are acutely induced by nicotine dissipate rapidly and so do the feelings of satisfaction. This quick cycle triggers the smoker to keep taking the drug to sustain the effects that make the drug enjoyable and avoid the withdrawal effects. ³⁰

Cognitive deficits

The withdrawal process occurs because of dependence, as the body gets habitual to the presence of the substance in its system. Inability to smoke for too long could make a regular smoker be irritable, depressed or cravings, depression, anxiety attention, and cognitive deficits as well as sleep disturbances, and a greater appetite. The withdrawal symptoms can start within a couple of hours after smoking the last cigarette that can quickly bring users back to smoking cigarettes.

If a smoker quits withdrawal symptoms are most noticeable in the initial few days following the last smoke and typically subside after several months. For some, however, withdrawal symptoms could last for months, and the degree of withdrawal symptoms seems to be determined by the genetics of the individual. ^30,31

Apart from its pleasant effects, nicotine temporarily increases cognition-related abilities like the capacity to maintain attention and store the information stored in your memory. However, long-term use of nicotine is linked with a decline in cognitive function and a higher risk of Alzheimer’s Disease, suggesting that any short-term improvement from nicotine does not outweigh the long-term implications for cognitive functioning.

Withdrawal symptoms

Additionally, those who have quit nicotine develop difficulties with neurocognitive functions, including problems in attention and memory. These withdrawal symptoms in the brain are now acknowledged as contributing factors to the continued smoking.34 A tiny study has also found that withdrawal can affect the quality of sleep for smokers who are extremely dependent and could be a contributing factor to relapse.

Additionally, the effects of the drug on a variety of neurotransmitters and the receptors for them, ^thirty various behavioral aspects can influence the intensity in withdrawal-related symptoms. For many smokers the smell, feel, and appearance of smoking a cigarette, as well as the process of getting, handling the lighting, and smoking cigarettes are all connected to the pleasures of smoking cigarettes and may make the withdrawal or craving more severe.

Learning processes within the brain link these signals to dopamine-induced dopamine spikes that are part of the reward system –similar to the effects that occur in other addictions to drugs. Nicotine replacement therapies like patches, gum, inhalers, and other medications specifically approved for the treatment of addiction to nicotine can help ease the physiological effects associated with withdrawal (see ” What are treatments for tobacco dependence?“) But, cravings typically persist because of the potency of these signals. Psychological therapies can assist smokers to discern the triggers that trigger cravings from their surroundings and devise strategies to stay away from these triggers and control the anxiety that can arise when triggers can’t be controlled. ^40,41

Are there other chemicals that could be contributing to the addiction to tobacco?

Research suggests that nicotine is not the only component in tobacco that can affect the addictive power of tobacco.

Smoking cigarettes is associated with a drastic decline in levels of monoamine oxidase (MAO) the key enzyme responsible for breaking down dopamine and also a decrease of MAO binding sites within the brain. ⁴² The change could result from a substance that is not yet identified in tobacco smoke that is not nicotine, since there is evidence that shows that nicotine doesn’t significantly alter MAO levels. Research on animals suggests that MAO inhibition causes nicotine to become stronger, but further studies are required to determine the extent to which MAO inhibition is a factor in the development of human dependence on tobacco. 

Animal studies have also demonstrated that acetaldehyde is a different chemical present in tobacco smoke, generated by the burning of sweeteners such as sugars significantly enhances the strengthening characteristics of nicotine. It could contribute to addiction to tobacco. ⁴³

Optimum dosing and supply technique for nootropic profit

A cigarette administers about 2 mg of absorbed nicotine. Nicotine a nootropic, limiting to 1-2mg a day is beneficial.

Supply strategies: danger for addictiveness from highest to lowest:

• Vaping
• Nasal nasal spray
• Nicotine inhaler
• Nicotine mouth spray
• Chewing gum (when correctly taken)
• Lozenges (when successfully taken, don’t eat)
• Nicotine patches [these administer nicotine over hours, resulting in a significantly lower chance of addiction than all the above, but on the flip side some users report not seeing as many cognitive benefits]

One examines of nicotine gum customers concluded “Amongst long-term customers (>/=90 days), 20% attributed their use to habit… Combining the outcomes of Research 1 and a couple of with different knowledge suggests only a few gum customers develop a dependence on the gum.” [ref] Nicotine gum/lozenges shouldn’t be consumed shortly, the packaging recommends ‘parking’ the gum/lozenge underneath your lip and letting it sit there for some time.

My review of nicotine as a nootropic

After studying an interview with Oxford transhumanist thinker Nick Bostrom I started to use nicotine as a nootropic. When requested if he has ever made any cognitive enhancers, he stated he experimented with nicotine gum. In his guide Superintelligence, he additionally mentions that nicotine gum helped him write the guide.

In its pure form, nicotine is a remarkable nootropic. Consumed in micro-doses of 1‑2 mg, 1‑4 times a day, it can produce a noticeable effect on mental performance. The European Commission’s Scientific Committee says: “In the brain, nicotine is clearly a stimulant at low doses.

Some notes on nicotine’s pharmacological results

• Nicotine will increase neurotransmitter ranges throughout the board, together with catecholamines (dopamine, adrenaline, and norepinephrine), beta-endorphins, serotonin, and even cortisol, the stress hormone, which is probably not so good a factor. [ref] See Wikipedia article for detailed refs.
• It additionally will increase acetylcholinesterase, the enzyme that breaks down acetylcholine, [ref]
• It will last for about 1-2 hours.
• The binding site with the very best affinity to nicotine is the alpha-4-beta-2-nicotinic receptor. Curiously, stimulation of this mandatory website ends in will increase in human progress hormone secretion.

Nootropic Advantages

• “In 2008, Paul Newhouse, director of the Heart for Cognitive Drugs at Vanderbilt College Faculty of Drugs in Nashville, in contrast, efficiency on a collection of cognitive duties in 15 people living with nonsmoking ADHD whereas sporting both a 7-mg nicotine patch or a placebo patch. After simply 45 minutes with the nicotine patch, the younger adults had been considerably higher at inhibiting an impulse, delaying a reward, and remembering a picture they’d seen. Psychologist Jennifer Rusted of the College of Sussex in Britain calls the drug “probably the most dependable cognitive enhancer that we presently have”.

Different misc advantages

• Decrease danger for Parkinson’s illness. Many years in the past researchers have seen a robust correlation between smoking and a decrease danger for Parkinson’s disease. Since then, a big physique of analysis has demonstrated nicotine is accountable for this. Some study suggests it might help treat Parkinson’s as effectively.

The long-run results of nicotine on sexual efficiency are unknown. However, there’s a correlation between smoking impotence.
• Toxicity – nicotine is poisonous at excessive ranges. This can be very poisonous to bugs, which is why many vegetation produce it. The precise LD50 focus of nicotine in people is controversial; however, lies someplace between .5-10 mg/kg. Extra essential to keep in mind is the vary for a deadly single dose, which is 30-60 mg in adults and 10 mg in kids. That is important to keep in mind with e-cigarettes, as a single vial of e-liquid can comprise 20 mg of nicotine – so they need to be avoided, kids! Dying from nicotine overdose is extraordinarily uncommon although, Between 2010-2012 just one demise from e-liquids was reported, which was a suicide.[wikipedia]
