Introduction

Background on Nicotine Addiction

Before discussing natural remedies for nicotine and its addiction, it is important to understand what nicotine is. It is a naturally occurring compound mainly present in the tobacco plant (Nicotiana tabacum) and a few other plants in the nightshade family. It is classified as an alkaloid, a type of organic compound that generally has psychological effects on humans and animals. Known for its psychoactive effects, nicotine is also recognised for its potential to cause addiction.¹ Nicotine dependency is a complicated and multifaceted condition that impacts the central nervous system and is characterised by a range of specific symptoms and indications.² Quitting smoking leads to the onset of withdrawal symptoms such as irritability, low mood, restlessness, and anxiety. The severity of these emotional disturbances can be comparable to that experienced by an individual seeking psychiatric outpatient care. Additionally, anhedonia, the sensation that life lacks enjoyment, may also arise during nicotine cessation.³

Importance of Natural Remedies

Effective approaches for managing tobacco addiction and nicotine dependence encompass behavioural therapy, along with cognitive behavioural therapy (CBT), motivational interviewing, acceptance and commitment therapy, and contingency management, or incentive-based interventions.⁴ In this article, we mainly focus on natural remedies for nicotine withdrawal, such as herbal treatments, vitamins, and lifestyle modifications.

Understanding Nicotine Withdrawal

Common Psychological Symptoms

• Irritability
• Anxiety
• Restlessness
• Difficulty in focusing
• Increased hunger
• Insomnia
• Powerful craving for nicotine
• Depression¹

Common Physical Symptoms

• Headache
• Fatigue
• Increased heart rate¹

Duration and Severity

Timeline of Symptoms After Quitting

Withdrawal symptoms tend to be most severe during the initial week after stopping, reaching their highest point in the first three days. After that, the severity of the symptoms generally decreases over the first month. Nonetheless, experiences can vary widely, and some individuals may face withdrawal symptoms for several months following cessation.⁵

Factors Affecting Withdrawal Intensity

Nicotine addiction factors were divided into five groups:

• Withdrawal symptoms
• Blood nicotine concentration
• The age at which smoking began
• Smoking frequency
• Smoking duration

Individuals with greater nicotine dependence often experience more intense withdrawal symptoms, which complicates the process of quitting. The greater the level of nicotine in the blood, the more challenging it is to stop smoking. The earlier a person began smoking, the more difficult it became to quit. Additionally, the regularity and duration of smoking influenced quit attempts; those who smoked more often and for longer periods found it significantly harder to stop.⁶

Herbal Treatments for Nicotine Withdrawal

Numerous tobacco cessation medications come with a high price tag, which has been identified as a barrier to accessing smoking cessation treatments in low- and middle-income nations. Additionally, these medications can cause side effects such as nausea, dry mouth, and drowsiness. Therefore, herbal remedies have emerged as a potential alternative for smoking cessation treatment, as they may be more accessible, less expensive, and associated with fewer side effects.⁷

Black Pepper (Piper nigrum)

A pertinent case report by Weleff et al. (2022) highlighted an unusual occurrence in which a former inmate used burnt black pepper as a means of self-medication to manage the symptoms of nicotine withdrawal. The patient stated that inhaling the smoke from the black pepper helped reduce withdrawal symptoms, including anxiety, irritability, and strong cravings for cigarettes.

Mechanism of Action

There are three mechanisms involved in alleviating nicotine withdrawal symptoms:

• Diminishing spontaneous desires, which are shown to be the most powerful type of craving and are closely related to lapses in abstinence
• The anxiety-reducing properties of piperine, as evidenced by preclinical research, exhibit sedative and antidepressant effects by decreasing oxidative stress in the brain
• The satisfaction of sensorimotor experiences that mimic tobacco smoking, such as sensations in the chest, a bitter-spicy flavour, and repetitive hand-to-mouth motions

Caution

Using burnt black pepper is not appropriate for common therapeutic practices due to possible health hazards from the smoke it produces.

Alternative

This discovery emphasises the need to explore the use of vaporised black pepper essential oil as a safer alternative. Research has indicated that aromatherapy with black pepper essential oil can greatly diminish cravings for nicotine, even outperforming other essential oils.⁸

Green Oat Extract (GOE) of Avena sativa L.

Avena sativa L., especially in its herbal wild green extract known as Neuravena, has demonstrated considerable promise in aiding the process of reducing or quitting smoking.

Mechanism of Action

Its mechanism of action is based on the inhibition of monoamine oxidase-B (MAO-B), which is responsible for increasing the levels of dopamine in the brain. This is particularly important for addressing nicotine addiction, as decreased dopamine levels result in withdrawal symptoms such as depression, sadness, and exhaustion.

Phytotherapeutic Approach

Avena sativa can therefore be considered a plant that provides a phytotherapeutic approach. Unlike nicotine replacement therapies (NRT), which primarily target nicotine receptors pharmacologically, it instead addresses the psychological and physiological factors that make smoking cessation more challenging, by enhancing sleep quality, reducing stress, and boosting overall wellbeing.⁸

Acanthopanax koreanum (AK)

Acanthopanax koreanum Nakai, part of the Araliaceae family and native to Jeju Island, South Korea, has been traditionally utilised as a tonic and sedative in herbal medicine. In contemporary pharmacology, the stem extract of this plant, especially when prepared as a 70% ethanol extract, demonstrates substantial promise in alleviating symptoms of nicotine dependence and withdrawal.

Mechanism of Action

A. koreanum exhibits various mechanisms:

• Diminishes cravings
• Stops dopaminergic sensitisation
• Eases withdrawal symptoms
• Restores the expression of proteins associated with addiction

Therefore, this plant may serve not only as a complementary treatment for quitting smoking but also as a long-term neuroprotective agent against the harmful impacts of nicotine intake.⁸

Cinnamon and Ginger Oil

The adjunct use of cinnamon and ginger oil markedly decreases oxidative stress and degenerative alterations caused by nicotine in the prefrontal cortex.⁸

St. John's Wort

St. John's Wort is a herb that contains various pharmacologically active compounds, including naphthodianthrones, phloroglucinol derivatives, and flavonoids. In addition to its antidepressant properties, it has also demonstrated smoking cessation effects.

Mechanism of Action

The extract of St. John's Wort primarily functions by blocking the reabsorption of norepinephrine and serotonin (5-HT) into presynaptic axons. Research has indicated that it is generally well-tolerated among smokers. Conversely, some studies suggest that this herb may be ineffective in smoking cessation.⁹

Vitamins to Quit Smoking

Smoking is linked to the reduction of plasma levels of vitamins A, E, and C, as well as antioxidants, leading to diminished resistance to oxidative changes in plasma. Research has shown that combining natural agents with pharmacological treatments is highly effective for quitting smoking.⁹ Below are five vitamins that may help with smoking cessation:

Vitamin C

Vitamin C is a vital nutrient that can support smokers in their efforts to quit, as it assists in cell repair and strengthens the immune system. Smokers generally have lower levels of vitamin C compared to non-smokers, requiring an additional 35 mg daily to fulfil their needs. Vitamin C is present in:

• Citrus fruits
• Berries
• Tomatoes
• Broccoli
• Brussels sprouts
• Potatoes

Vitamin E

Vitamin E is recognised for its antioxidant qualities and may also be advantageous for individuals who want to quit smoking. It aids in reducing oxidative harm caused by nicotine, which can result in scarring on the walls of blood vessels. This vitamin also facilitates the formation of red blood cells and enhances immunity, assisting in fighting viruses while potentially alleviating the cardiovascular strain of smoking. Vitamin E is present in:

• Sunflower seeds
• Nuts
• Vegetable oils
• Peanut butter
• Avocado
• Mango
• Leafy greens

Zinc

Zinc is important for the regulation of the immune system and the synthesis of collagen and dopamine. Individuals who smoke tend to have lower concentrations of zinc due to its relationship with copper, which is often found at higher concentrations in the bloodstream of smokers. Zinc is present in:

• Oysters
• Bananas
• Seeds
• Beef
• Shellfish
• Chickpeas

Vitamin B12

Vitamin B12 is a water-soluble vitamin essential for several bodily functions, including the production of red blood cells and maintaining nerve health. Smoking can reduce the body's ability to absorb vitamin B12 due to elevated levels of cyanide in the bloodstream, potentially resulting in deficiency and leading to health issues such as fatigue and memory loss. Incorporating B12 into the diet may promote improved mood, enhanced energy, better cognitive function, and nerve health, all of which are beneficial in addressing cravings and withdrawal symptoms. Vitamin B12 is present in:

• Fish
• Poultry
• Eggs
• Dairy products
• Cereals
• Soy milk

Vitamin D

Vitamin D helps protect the lungs from the harm caused by smoking and can reduce the rate of decline in lung function over time. It is recognised for its anti-inflammatory effects and its ability to support the immune system during the process of quitting. Vitamin D is present in:¹⁰

• Oily fish
• Egg yolk
• Cheese
• Oranges
• Mushrooms
• Cereals

Lifestyle Changes to Ease Nicotine Withdrawal

People who are accustomed to smoking may still experience nicotine cravings long after quitting, as the body adjusts to no longer being dependent on nicotine. In addition to physical cravings, psychological cravings may also arise due to environmental triggers, such as being near other smokers, which can alter mood and elevate blood pressure.⁵

Physical Activity

To reduce nicotine cravings, engaging in enjoyable physical activities, such as going for a walk, can be highly effective.⁵

Mindfulness and Meditation

Consider practising meditation or other relaxation methods, such as having a massage, taking a warm bath, or practising deep breathing by inhaling through the nose and exhaling through the mouth for a count of ten breaths.⁵

A Healthy Diet to Maintain Body Weight

Aligning calorie consumption with physical activity levels will assist in reaching and sustaining a healthy body weight.⁵

Social Support

Social support groups, whether face-to-face or virtual, offer a space for people to exchange their experiences, gain support, and learn from others who are also working to stop using nicotine.¹

Behavioural Techniques

Behavioural treatment methods provide smokers with effective strategies to avoid or manage triggers, deal with cravings, and alleviate withdrawal effects. These programmes often encompass a broad range of subjects, such as:

• Guidance on quitting smoking
• Evaluation of previous quit attempts and insights that can be gained from them
• Analysis of the current motivation level to quit
• Recognition of cues and triggers associated with smoking, and techniques to prevent or manage them
• Advice on mood management and encouragement of adherence to treatment (including proper use of medication) and ongoing involvement
• Skill development and self-management of withdrawal symptoms
• Accepting support from others
• Addressing related health concerns such as stress, irritability, and other substance use issues⁴
