Drugs like cocaine, meth, and alcohol are often known to have an intense stimulatory effect on your central nervous system. This causes them to put immense pressure on your heart and blood vessels, which can cause serious damage to your circulatory system.¹ 

When such stimulants enter your bloodstream, they trigger a surge of adrenaline, leading to increased heart rate and blood pressure, causing your blood vessels to constrict.¹ With extended drug use, these destructive effects can cause heart attack, strokes, arrhythmias, and even sudden cardiac death.

How Different Drugs Affect the Circulatory System: Substance-by-Substance

Using different drugs affects your circulatory system differently, based on their composition, frequency of use, and the quantity taken. Here is a breakdown on how different types of drugs are commonly consumed and what they do to your body’s circulatory system ²

Stimulants

For simulants like cocaine, methamphetamine, and amphetamines, the intense stimulation caused to the nervous system causes immense pressure on your heart and blood vessels. When these drugs enter your bloodstream, they cause a surge an adrenaline rush leading to increased heart rate and constricted vessels. Chronic use of stimulants also thickens the walls of your blood vessels, paired with the increased blood pressure, making them more prone to ruptures and clot formation.³ 

Depressants & Opioids

As for depressants like heroin and opioids, they have an opposite effect compared to stimulants, as they slow down your heart and cause respiratory issues.³ Meaning that prolonged use of opioids can lead to reduced oxygen delivery throughout the body, causing strain on the heart as it works under oxygen-deprived conditions.

Injectable opioids also carry a serious risk of vein collapse and clots that can permanently damage the heart tissues, resulting in heart failure and even life-threatening complications.⁴  

Alcohol & Other Substances

Although legal, alcoholism has been a serious concern for a lot of people suffering from addiction, as it is a potent cardiac depressant. Long-term alcoholism can cause alcoholic cardiomyopathy, the weakening of the heart muscle, leading to an irregular rhythm, which can lead to eventual heart failure.⁵

Similarly, nicotine is another readily available drug that accelerates plaque buildup in your arteries, known as atherosclerosis, which reduces oxygen in the blood and promotes clotting.⁶ Additionally, drugs like cannabis and synthetic drugs can raise heart rate and blood pressure, which can cause a cardiac event in at-risk individuals.

What the Circulatory System Is and Why It’s Vulnerable

The circulatory system is the blood-carrying system in your body, consisting of the heart, blood, and a vast network of vessels throughout the body. This network is responsible for transporting oxygen and all the absorbed nutrients to the rest of the body.⁷ 

However, because this system is extremely sensitive to chemical and hormonal changes, drugs can cause significant changes to it over extended use, because even small disruptions can compromise circulation and trigger cardiovascular disease.

 

Expert Opinion on the Impact of Drug Use on the Circulatory System

“The human body was not made to abuse drugs, and continued use can lead to chronic circulatory system issues. Drugs like cocaine and methamphetamine can cause narrowing of blood vessels, increased heart rate, and elevated blood pressure. The circulatory system struggles to cope with the constant strain, ultimately leading to long-term health consequences. Proper addiction treatment for such high-risk cases requires timely intervention!”

How Drug Use Damages Circulation & Heart

There are several mechanisms at work when a drug is introduced to your circulatory system that can cause damage. These damages can range from lightly inconveniencing to life-threatening.

• Cardiac Workload Increase: When stimulants are introduced to your nervous system, it may overstimulate the heart, causing hypertrophy and reduced efficiency of the heart.
• Oxygen Imbalance: When using a depressant, your breathing slows down, limiting the oxygen intake of your body. This cuts down the oxygen supply to your heart tissues.
• Vascular Injuries: Many illicit substances can cause inflammation or spasms within the arteries, promoting clot formation.
• Metabolic Changes: The use of drugs can alter the glucose and cholesterol levels of your body

Signs and Symptoms of Circulatory Damage

Circulatory and cardiac damage is often easy to spot since its signs and symptoms are very apparent.⁸ If drugs are impacting your circulatory system, you’d feel:

• Constantly out of breath
• Lightheaded with little exercise
• Chest pain or tightness
• Breathing-related issues
• Consistent nausea and vomiting
• Feeling fatigued more often
• Swelling in the legs, hands, or face
• Experiencing heart palpitations

Specific Complications & Risks of Circulatory System Damage

Prolonged drug addiction and substance abuse can lead to complications in circulatory system diseases.⁹ Some of the most severe cases include the development of:

Aneurysms

Aneurysms are weak areas in your blood vessels, mainly arteries, that tend to swell and can rupture in high-pressure environments. Consistent drug abuse weakens the blood vessels and leads to frequent development of aneurysms in seemingly healthy adults.

Arrhythmias

Since excessive drug use can put a strain on your heart, a common complication is arrhythmia. This condition deals with irregularly high or low heartbeat, which tends to impact your breathing and overall body.

Atherosclerosis

Hard drugs such as cocaine and meth tend to cause atherosclerosis and can even induce the onset of premature heart disease. It leads to the buildup of plaque in the arteries and slows blood flow in the long run.

Blood Pressure Conditions

Most people who are brought to the emergency room for drug use and potential overdose exhibit high or low blood pressure issues. If patients tend to abuse a variety of drugs, they may develop these blood pressure conditions chronically.

Cardiomyopathy

Almost all drugs have the potential to cause cardiomyopathy or weakening of heart tissue in some capacity. This leaves your heart vulnerable to other conditions and strain, which can later cause a stroke or heart failure.

Heart Valve Disease

Heart valve disease impacts the 4 valves in your heart that are supposed to keep oxygenated and deoxygenated blood in their own paths. With long-term drug addiction, these valves can deteriorate or weaken, causing many issues with oxygenation.¹⁰

Heart Failure

Over 6 million people in the U.S. have heart failure, and one of the contributing reasons is drug addiction.¹¹ During heart failure, the heart is unable to pump enough oxygenated blood to the organs, leading to a total body shutdown.

Stroke

A stroke is a life-threatening emergency that needs immediate medical attention. It typically occurs when excessive drug use prohibits blood flow to the brain and sends the body into shock.

How To Prevent Addiction From Getting Out Of Hand

All addiction has the potential to grow into a severe medical issue that may cause issues in the circulatory system of the body. This is why a preventive approach is necessary since your heart and blood vessels are delicate and cannot go back to their original functionality and health once they’re badly damaged.

Some tips to prevent addiction from getting out of hand include:

• Reaching out to your friends and family for help
• Considering addiction treatment while there is still time
• Avoiding the mixed use of drugs since it is harder on the body
• Not withdrawing from drug use immediately
• Reaching out as soon as relapse occurs
• Building the proper coping mechanisms to correct addictive behavior

Frequently Asked Questions

Are the Cardiovascular Effects of Addiction Reversible?

If the damage to your circulatory and cardiovascular system is low to moderate, then medical intervention can reverse the damage to some extent. However, severe damage puts patients at risk of lifelong heart issues, which is why excessive drug use should be avoided at all costs.

How Soon After Quitting Will my Blood Pressure or Heart Rate Return to Normal?

There is no defined time frame for when your blood pressure and heart rate begin to return to normal after quitting drugs. Most patients have to eat healthy and make lifestyle changes, such as exercise, to promote a healthier body.

Can Drug Use Cause Heart Damage Even If I’m Young and Healthy?

Yes, there is no age at which drug use causes more or less heart damage. Even if you’re a young and healthy individual, excessive drug use or mixing drugs with alcohol or other substances can cause irreparable and severe damage to your heart.
