Addiction to various substances can have adverse effects on the muscular system, which consists of over 700 skeletal, smooth, and cardiac muscles. While muscle twitching can be caused by factors such as dehydration, fatigue, and stress, certain drugs and alcohol can also contribute to this condition. Opioid abuse, for instance, has been linked to myoclonus, a clinical term for uncontrollable muscle movement, which can present as localized or full-body twitching. Similarly, alcohol consumption can interfere with the brain's chemical messages to skeletal muscles, leading to muscle twitching and spasms. Additionally, chronic alcohol myopathy affects a small percentage of individuals with alcohol use disorder, further emphasizing the connection between addiction and muscle abnormalities. Other substances, such as anabolic steroids, cocaine, and methamphetamine, can also damage the muscular system, leading to issues with movement, seizures, and cardiovascular problems. Understanding the impact of addiction on muscle twitching is crucial for developing effective treatment plans and promoting overall health and well-being.

What You'll Learn
Alcohol withdrawal and muscle twitching
Alcohol withdrawal can cause muscle twitching and spasms. This is because alcohol interferes with the chemical messages the brain sends to the skeletal muscles, promoting dehydration and electrolyte imbalances responsible for involuntary muscle movement. Alcohol increases the activity of GABA and decreases the activity of glutamate, causing sedation and muscle relaxation. During alcohol withdrawal, the inhibitory effects of GABA are reversed, and excessive excitatory messages are sent to the muscle tissue, triggering spasms and twitching.
Muscle twitching and spasms are two forms of involuntary contraction. Twitching is a short-lived, jerky movement, while spasms are more intense and sustained muscle tightening that causes pain. These involuntary contractions can be the result of inappropriate nerve activity in the central nervous system (CNS) or factors like dehydration, fatigue, intense exercise, stress, and electrolyte imbalances. Drinking places stress on the neuromuscular system, leading to a loss of muscle mass and appropriate functioning.
Chronic alcoholic myopathy (muscle dysfunction) affects approximately 0.5% to 2% of people with alcohol use disorder (AUD), making it the most common clinical sign of AUD. If you are experiencing muscle spasms due to substance use or withdrawal, it is important to seek medical attention for sudden, severe, or new symptoms.
Alcohol withdrawal syndrome (AWS) is the collection of alcohol withdrawal symptoms that typically occur when people who drink alcohol regularly suddenly stop or reduce their alcohol intake. AWS usually starts with general hangover symptoms within 6 to 12 hours after the last drink. Muscle tremors, spasms, or twitching can result from AWS and are one of the most common symptoms, usually starting within a few hours of the last drink and lasting up to a few days. However, the severity and duration of AWS symptoms can vary, and some people may have only mild hand tremors or muscle twitching, while others may experience more serious problems like full-body seizures or delirium tremens (DTs).
It is important to be aware that alcohol withdrawal can lead to serious or even deadly complications. AWS can lead to serious health problems, so it is important to only go through withdrawal under medical supervision.

Opioid abuse and myoclonus
Addiction to opioids can cause myoclonus, or involuntary muscle twitching and jerking. Myoclonus is not an uncommon or unexpected side effect of opioid use or abuse. It is a symptom requiring a more precise assessment, especially in cancer patients treated with opioids. The incidence of opioid-related myoclonus varies widely, ranging from 2.7% to 87%.
Myoclonus can occur in patients on chronic therapy with most opioids, including morphine, hydromorphone, fentanyl, meperidine, and sufentanil. Higher doses more frequently result in myoclonus, but the dose relationship is variable. Myoclonus can occur with all routes of administration. Current research implicates the 3-glucuronide opioid metabolites as one likely cause of neuroexcitatory side effects.
Opioid-induced myoclonus is often preceded by long periods of nocturnal myoclonus. It usually occurs in the extremities, starting with occasional random jerking movements. With continued opioid administration, the jerking may increase in frequency. At the extreme, there is constant jerking of random muscle groups in all extremities. As myoclonus worsens, patients may develop other neuroexcitatory signs like hyperalgesia (increased sensitivity to noxious stimuli), delirium with hallucinations, and eventually grand mal seizures.
Treating opioid-related myoclonus begins, and can often end, with ceasing opioid drug use. When a person is using opioids to manage a chronic pain issue or pain related to cancer, they will have to explore alternative pain management options. If a person is struggling with opioid addiction, they will have to pursue an addiction treatment program.

Stimulant drugs and muscle damage
Addiction can indeed cause muscle twitches and spasms, which are two forms of involuntary contraction. While muscle spasms can be caused by many factors, alcohol is the most preventable cause. Alcohol withdrawal can cause muscle twitching and spasms by interfering with the chemical messages the brain sends to the skeletal muscle, promoting dehydration, and causing electrolyte imbalances responsible for involuntary muscle movement.
Stimulant drugs can also have detrimental effects on muscle control. Chronic use of powerful stimulants like cocaine and methamphetamine can produce brain damage, which can compromise the musculoskeletal system. Stimulant drugs can also cause deterioration of the heart muscle (cardiomyopathy), high blood pressure, and heartbeat irregularities (arrhythmias).
The muscular system is a complex organ system that consists of over 700 skeletal muscles, smooth muscles, and cardiac muscles (the heart). Nearly every movement in the body occurs through this system. Therefore, damage to this system can lead to issues with movement, chronic pain, and damage to other organ systems.
Drugs can cause myotoxicity by interacting with muscle organelles, changing muscle antigens, and causing systemic effects such as instabilities in electrolytes or limiting the oxygen supply for energy production, which secondarily affects muscle function. The most prevalent and well-documented drug class with unintended myotoxicity is statins. However, researchers have also found that zidovudine-induced myopathy shares features of a mitochondrial myopathy, suggesting that apoptosis may play a role in its progression.

Anabolic steroids and muscle tears
Addiction to certain substances can cause muscle twitching and spasms. Alcohol withdrawal, for instance, can lead to muscle twitching and spasms by interfering with the chemical messages the brain sends to skeletal muscles, causing a loss of muscle coordination.
Anabolic steroids are synthetic testosterone derivatives designed to maximize anabolic activity and minimize androgenic effects. They are often abused by athletes and bodybuilders to build muscle tissue. However, when these substances are abused, they can have adverse effects on the body, including muscle tears and ruptures.
Abuse of anabolic-androgenic steroids (AAS) has become a significant substance abuse problem, especially among athletes and bodybuilders. AAS abuse can lead to tendon rupture, with many users reporting accumulated long-term steroid use before their tendon ruptures. The elevated risk of tendon rupture is attributed to the high doses of AAS, which can be 3.5 to 40 times the normal male endogenous production of testosterone.
While the exact mechanism of tendon rupture in AAS users is not fully understood, it is hypothesized that the high doses of steroids may alter the structural properties of tendons, making them more susceptible to injury. Additionally, the increased muscle mass and strength gained through AAS abuse may exceed the structural capacity of the tendons, leading to rupture under heavy loads.
Furthermore, anabolic steroids can also cause muscle tears indirectly by affecting the musculoskeletal system. The musculoskeletal system consists of muscles, tendons, ligaments, and bones, and damage to this system can result in issues with movement and chronic pain. AAS abuse can alter muscle growth and lead to infections in the muscles and bones, compromising the musculoskeletal system and increasing the risk of muscle tears and other injuries.
In conclusion, anabolic steroid abuse can directly contribute to muscle tears and tendon ruptures, while also indirectly affecting the musculoskeletal system and increasing the likelihood of muscle-related injuries. It is important to understand the risks associated with anabolic steroid abuse to prevent and address these adverse effects effectively.

Muscle twitches and hypnic jerks
Opioid use has also been linked to myoclonus, a category of rapid, involuntary muscle contractions characterised by twitching or jerking movements. Opioids can contribute to myoclonus even after brief or relatively small doses, and it is considered a common side effect. However, treating opioid-induced myoclonus typically involves ceasing opioid use.
Hypnic jerks, also known as sleep starts, are sudden, involuntary muscle twitches that occur as an individual falls asleep. They are generally harmless and are often experienced as a jolt or falling sensation. These jerks are thought to be caused by a misfire between nerves in the reticular brainstem during the transition from wakefulness to sleep. While stress, fatigue, and excessive caffeine intake can increase the frequency of hypnic jerks, they are typically benign occurrences.
It is important to note that muscle twitching can be influenced by various factors, including stress, anxiety, caffeine consumption, physical exhaustion, and specific sleep disorders or neurological conditions. While occasional twitches are typically harmless, frequent or persistent twitches that interfere with daily life may warrant medical attention.
