LSD, or lysergic acid diethylamide, is a hallucinogenic drug that affects mood, judgment, and behaviour. While the specific link between LSD and muscle spasms is unclear, the drug has been associated with rhabdomyolysis, a condition involving muscle cell injury and subsequent pain and weakness. Illicit drugs, including stimulants like cocaine, are known to cause rhabdomyolysis, and LSD users have presented with this condition in rare cases. Furthermore, LSD abuse can lead to issues with movement, seizures, and cardiovascular problems, all of which can indirectly impact muscles and cause spasms through violent, uncontrollable movements or cardiovascular complications.

LSD and rhabdomyolysis
Rhabdomyolysis is a syndrome that results from skeletal muscle injury. It involves the release of intracellular contents secondary to muscle cell injury and generally presents with muscle pain and weakness. Illicit drugs, including phencyclidine, MDMA ("ecstasy"), and cocaine, are frequently documented as causing rhabdomyolysis.
Although LSD is frequently listed as a cause of rhabdomyolysis, there are only limited reports of rhabdomyolysis in patients who have ingested LSD. One such report describes a previously healthy patient who suffered rhabdomyolysis after LSD ingestion.
The discussion around LSD-associated rhabdomyolysis outlines potential mechanisms and management strategies. Consultation psychiatrists may be called to assist in managing acute mental-status changes or agitation associated with LSD intoxication, in addition to facilitating subsequent chemical dependency treatment.
The incidence and mortality rates of drug-induced rhabdomyolysis are uncertain, largely due to underreporting. However, it is no longer considered a rare occurrence due to the introduction of more potent drugs into clinical practice.

Muscle spasms and strokes
While LSD has been documented as a cause of rhabdomyolysis, a condition involving muscle cell injury that presents with muscle pain and weakness, there are only limited reports of rhabdomyolysis occurring in patients who have ingested LSD. Therefore, it is unclear whether LSD can directly cause muscle spasms. However, it is important to note that LSD can cause changes in muscle sensations, including shaking and pressure, which may be similar to the symptoms of rhabdomyolysis.
On the other hand, muscle spasms and spasticity are commonly associated with strokes. Spasticity is a condition that causes stiff or rigid muscles, affecting approximately 25% to 43% of stroke survivors in the first year after their stroke. It occurs when a muscle involuntarily contracts during movement and is commonly observed in the elbow, wrist, and ankle. Spasticity can make everyday activities challenging and significantly impact a person's quality of life.
The onset of spasticity typically occurs between 3 and 6 weeks after a stroke, and the muscular symptoms tend to increase over time. If left untreated, spasticity can lead to permanent muscle shrinkage and contraction, with joints locked in abnormal and potentially painful positions, a condition called contracture. Spasticity may also cause significant difficulties with daily tasks such as bathing, eating, and dressing.
To manage spasticity after a stroke, it is essential to keep the affected limbs moving and prevent staying in one position for too long. Regular exercise and physical therapy can help ease muscle tightness, prevent muscles from shortening, and maintain a full range of motion. Treatments and lifestyle adjustments, such as working with an occupational therapist and using mobility aids, can also help reduce the severity of spasticity and improve overall quality of life. In severe cases where other treatments are ineffective, surgery on the affected muscle, joint, or tendon may be considered as a last resort.

LSD and muscle atrophy
LSD (lysergic acid diethylamide) is a potent psychedelic drug that affects a person's mental state and can cause hallucinations. While LSD is not known to directly cause muscle atrophy, its impact on the brain and nervous system can indirectly lead to muscle damage and atrophy.
LSD activates serotonin receptors in the brain, stimulating serotonin production in the cortex and deep brain structures. This overstimulation causes changes in perception, thoughts, attention, and emotions. Additionally, LSD alters brain activity in several regions, resulting in hallucinations and distorted sensory experiences.
The impact of LSD on the brain can lead to impaired judgment and motor coordination. Chronic use of LSD and other drugs can compromise the vascular system in the brain, increasing the risk of stroke. A stroke occurs when there is a disruption in blood flow to the brain or a rupture of blood vessels, depriving the brain of oxygen and nutrients. This can lead to tissue damage, paralysis, weakness, or loss of function in limbs, which may contribute to muscle atrophy over time.
While muscle atrophy due to LSD use may be rare, there have been limited reports of rhabdomyolysis, a condition involving muscle cell injury, muscle pain, and weakness, following LSD ingestion. The exact mechanisms of LSD-associated rhabdomyolysis are not fully understood, and further research is needed to establish a direct link between LSD and muscle atrophy.
It is important to note that LSD use carries risks, including the potential for negative experiences or "bad trips," flashbacks, and the triggering or worsening of mental health conditions such as anxiety, schizophrenia, or psychosis. The impact of LSD on the brain and nervous system can have indirect effects on the muscular system, highlighting the importance of understanding the comprehensive effects of this substance.

Muscular system damage
LSD is a dangerous hallucinogenic drug that affects mood, judgment, and behaviour. It is a substance that temporarily alters a person's mental state. The muscular system is a complex system that consists of over 700 skeletal, smooth, and cardiac muscles. It permits movement, helps circulate blood throughout the body, and maintains posture.
Damage to the muscular system can lead to issues with movement, damage to other organ systems, and chronic pain. Powerful stimulant drugs such as cocaine, ecstasy, and methamphetamine can damage important areas in the brain, which can result in muscle atrophy or damage to the musculoskeletal system. Chronic drug use can also lead to seizures that can damage the muscles through violent uncontrollable movements.
Additionally, LSD can trigger long-term psychosis or schizophrenia. Flashbacks, also known as hallucinogen persisting perception disorder (HPPD), and severe disorientation can occur after a single dose. While LSD does not cause physical dependence, it can increase the risk of overdose due to tolerance buildup.
There have been limited reports of rhabdomyolysis, a condition involving the release of intracellular contents secondary to muscle cell injury, in patients who have ingested LSD. However, the exact mechanisms and management of LSD-associated rhabdomyolysis require further investigation.

Cardiovascular issues and LSD
LSD, or lysergic acid diethylamide, is a psychedelic drug that affects a person's senses, thinking, sense of time, and emotions. It is a synthetic chemical derived from ergot, a fungus that infects rye (grain). LSD is typically ingested orally in capsules, pills, sugar cubes, chewing gum, or liquid drops. It can also be sold as a liquid, in tablet form, or in capsules.
While LSD is known to cause perceptual changes, such as hallucinations, and mood changes, there is limited evidence directly linking LSD to cardiovascular issues. However, recreational drug use, in general, has been associated with profound changes in the heart and circulation, contributing to a significant proportion of drug-related morbidity.
Cocaine, amphetamines, and ecstasy are known to have adverse effects on the cardiovascular system, primarily related to sympathetic nervous system activation. This activation can lead to tachycardia, vasoconstriction, unpredictable blood pressure effects, and arrhythmias, depending on the dosage and the presence of coexisting cardiovascular disease.
While LSD itself may not be directly linked to cardiovascular issues, it is important to note that it falls under the category of recreational drugs. The abuse of recreational drugs is common, and doctors often have to manage and treat their associated ill effects, including potential cardiovascular complications. Additionally, recreational drugs are often taken together, resulting in complex synergistic interactions that could have detrimental effects.
Recent research has indicated that classic psychedelic use, including LSD, may have beneficial effects on cardiometabolic diseases such as heart disease. A national survey-based study found that lifetime classic psychedelic use was associated with a 23% lower odds of heart disease in the past year. However, it is essential to approach these findings with caution, as the complex interactions between different drugs and individual variations can influence the overall impact on cardiovascular health.
