Nicotine is a stimulant that affects the central nervous system. It is a compound that occurs naturally in large amounts in tobacco plants. While nicotine has many well-known side effects, its impact on muscle cramps is less commonly discussed. Nicotine poisoning can cause muscle twitching, and some sources indicate that nicotine can cause muscle cramps. However, it is unclear whether nicotine directly causes muscle cramps or if this is an indirect effect of nicotine-induced muscle weakness.

| Muscle Twitching | Common side effect |
| Muscle Spasms | Caused by irritation of the eyelid or eye surface area |

What You'll Learn
Nicotine poisoning and muscle cramps
Nicotine is a naturally occurring compound found in large amounts in tobacco plants. It is a mild stimulant that affects the central nervous system. When consumed in large quantities, nicotine acts as a poison, causing nicotine poisoning.
Nicotine poisoning results from taking too much nicotine, which can happen through ingestion or inhalation. It is rapidly absorbed by the body. In young children, ingestion of 1 to 2 mg of nicotine has been associated with signs of toxicity or poisoning.
Symptoms of nicotine poisoning include:
- Vomiting
- Seizures
- Involuntary muscle twitching and cramps
- Abnormal heart rhythms
- Slow heart rate
- Fluctuating blood pressure
- Muscle paralysis
- Buildup of fluid in the lungs
If left untreated, nicotine poisoning can lead to death, usually due to heart failure.
In addition to nicotine poisoning, chronic nicotine use can cause neuroadaptations and contribute to nicotine addiction and withdrawal symptoms. Withdrawal from nicotine can also produce somatic effects such as twitches, tremors, and elevated anxiety levels.
While nicotine can cause muscle twitching, there are other potential causes, including stress, exercise, caffeine consumption, and irritation of the eye or eyelid.

Muscle twitching and nicotine
Muscle twitching refers to small muscle contractions. There are many causes of muscle twitching, including stress, exercise, caffeine consumption, and nicotine use. Nicotine is a mild stimulant that affects the central nervous system. When consumed in high concentrations, nicotine can cause nicotine poisoning, which can lead to muscle twitching. In addition, nicotine withdrawal can also cause somatic effects such as twitches and tremors.
Nicotine poisoning occurs when an individual ingests or inhales too much nicotine, resulting in a buildup of the neurotransmitter acetylcholine at the synapses, which disrupts nerve impulses. This leads to overstimulation of the neurons and can cause a range of symptoms, including muscle twitching, seizures, abnormal heart rhythms, and vomiting. In severe cases, nicotine poisoning can even cause death within an hour, usually due to heart failure or muscle paralysis.
While nicotine poisoning is a serious concern, it is important to note that not all cases of muscle twitching are caused by nicotine use. Other potential causes include chronic kidney disease (CKD), myopathy, neuropathy, and serotonin syndrome. CKD can alter the body's balance of fluids and electrolytes, leading to muscle spasms, while myopathy and neuropathy can cause muscle cramps, stiffness, and twitching, particularly in the hands and feet. Serotonin syndrome occurs when there are high levels of serotonin in the body, which can also lead to muscle twitching.
In addition to these causes, muscle twitching can also be a result of excessive sweating, intense exercise, or fluid loss due to vomiting or diarrhea. Certain drugs, including diuretics and antidepressants, have also been linked to muscle twitches or spasms. It is always recommended to consult a doctor if muscle twitching persists or is accompanied by other symptoms, as they can advise on medication adjustments or alternative treatments.
Furthermore, research on the impact of nicotine-containing aerosol in e-cigarettes has indicated potential negative effects on muscle function. Studies on male mice have shown that exposure to nicotine-containing aerosol can impair locomotor muscle function, reduce muscle force development, and interfere with muscle repair. These findings suggest that chronic nicotine exposure may have detrimental effects on muscle health and regeneration.

Nicotine's effect on muscle repair
Nicotine is a compound found in tobacco products that can be addictive and harmful to the body. While it is known to have some positive effects on athletic performance, such as increased heart rate, blood pressure, and flow, there is evidence that nicotine can negatively impact muscle repair and growth.
A 2017 review found that nicotine interferes with how cells make proteins necessary for muscle repair. This is supported by an older study from 2007, which found that smoking reduced the production of proteins for muscle repair and suppressed genes responsible for maintaining muscle. Additionally, nicotine may worsen muscle breakdown.
The negative impact of nicotine on muscle repair is further demonstrated in experimental models of transected tendons. Animals administered nicotine tartrate showed an increased gap in the repair site, along with fibroblast degeneration and irregular fibril organization. These findings provide clear evidence of the harmful effects of nicotine on the musculoskeletal system.
Furthermore, nicotine can alter sensitivity to muscle tension and activity, particularly in female smokers. This alteration in sensitivity may be due to the impact of nicotine on testosterone and cortisol levels. Nicotine can reduce testosterone production, which is crucial for muscle growth and performance. Concurrently, it can increase cortisol levels, contributing to the breakdown of muscle tissues and impairing muscle growth, recovery, and performance.
While nicotine may have some positive effects on athletic performance, the weight of evidence suggests that its negative impact on muscle repair and growth is significant. Further research is necessary to fully comprehend its complex effects on the body.

Nicotine and muscle contractions
Nicotine is a mild stimulant that affects the central nervous system. It is a naturally occurring compound found in large amounts in tobacco plant leaves. When consumed, nicotine causes the cholinergic neurons at the cholinergic receptors in the body to get excited. This is the same response the body's nervous system has when poisoned by nerve agents such as sarin gas.
Nicotine poisoning can result from taking too much nicotine, which can happen accidentally or due to nicotine overdose. Symptoms of nicotine poisoning include vomiting, seizures, involuntary muscle twitching, abnormal heart rhythms, a slow heart rate, fluctuating blood pressure, and in high concentrations, death, often due to muscle paralysis. Muscle twitching refers to small muscle contractions.
Nicotine withdrawal can also produce somatic effects such as twitches, tremors, and bradycardia. In addition, chronic exposure to nicotine-containing e-cigarette aerosol has been shown to decrease the maximal force produced by muscles, impair muscle recovery, and interfere with muscle repair in male mice.
Therefore, nicotine can cause muscle contractions, especially in the legs, and may also impair muscle recovery and force development.

Nicotine's impact on muscle force
Nicotine is a bitter-tasting compound that naturally occurs in large amounts in tobacco plant leaves. It is a stimulant that, when consumed in large quantities, causes the cholinergic neurons at the cholinergic receptors in the body to become excited. This is similar to the body's nervous system response to poison.
Nicotine poisoning can result from consuming too much nicotine, and it can act as a stimulant before rapidly turning into a depressant. Vomiting, seizures, and involuntary muscle twitching are all symptoms of nicotine poisoning. In high concentrations, nicotine may cause death within an hour, often due to heart failure, muscle paralysis, and fluid buildup in the lungs.
Nicotine products, such as cigarettes, can cause muscle twitching, especially in the legs. Additionally, nicotine withdrawal can cause somatic effects such as twitches and tremors.
While the impact of nicotine on muscle force has not been extensively studied, some research suggests that exposure to nicotine-containing aerosols impairs locomotor muscle function, limits exercise tolerance, and interferes with muscle repair. In male mice, nicotine-containing aerosol reduced the maximum force produced by the extensor digitorum longus (EDL) muscle by 30-40% and decreased running speed by 8%. Furthermore, nicotine aerosol-exposed mice recovering from an injury only regained 80% of their original muscle force.
These findings indicate that nicotine may negatively affect muscle force and regeneration, potentially due to compromised glucose metabolism and contractile function.
