What Cocaine Does to Your Body

What Is Cocaine?

Cocaine is classified by the Drug Enforcement Administration (DEA) as a Schedule II controlled substance, meaning it poses risks of abuse, dependence, and adverse health consequences. Despite this, cocaine use is on the rise, and it remains a popular street drug that is used by up to 21 million people around the world.

Created from the leaves of the coca plant, cocaine generally comes in two forms. When cocaine appears as a white powder, it can be injected, smoked, or snorted. When it appears in rock crystal form – also referred to as crack cocaine – the drug is smoked. Often, cocaine is mixed – or cut – with other substances, such as fentanyl. This increases the risk of using a product that contains other drugs.

Although each method of abuse comes with different short and long-term side effects, both cocaine and crack cocaine pose a high risk of fatal outcomes.

When taking cocaine, the effects are felt relatively quickly as the drug directly enters the bloodstream before reaching the brain. Smoking cocaine causes an intense but short high that lasts around five to 10 minutes. If a user is snorting cocaine, the high will last approximately 15 to 30 minutes.

What Cocaine Does to Your Brain

Cocaine increases dopamine activity in the brain’s reward system. Dopamine is involved in pleasure, motivation, reward, and reinforcement. A fast dopamine increase can create intense euphoria and reinforce continued cocaine use.

With repeated use, cocaine can disrupt the brain’s reward pathway. This can reduce pleasure without cocaine and increase cravings, compulsive use, and relapse risk.

When cocaine leaves the bloodstream, a person may experience a crash. A cocaine crash can involve stress, anxiety, fatigue, depression, irritability, sleep problems, panic symptoms, and intense cravings. Fear of crashing, along with the brief high, can promote repeated use and binge patterns.

Increased Dopamine and Risk of Cocaine Addiction

Since cocaine’s effects are brief, some people use it repeatedly during one session. Repeated cocaine use can disrupt dopamine signaling and the brain’s reward system. These changes may increase tolerance, cravings, and addiction risk.

People who develop cocaine dependence may feel depressed, anxious, irritable, or emotionally unstable without the drug. Cravings may lead them to continue using cocaine for temporary relief or pleasure. This cycle may progress into stimulant use disorder, where cocaine use continues despite health problems, relationship conflict, work issues, financial harm, or legal consequences.

Regular cocaine use may lead a person to need higher doses to feel the same effects. Tolerance, cravings, withdrawal symptoms, and loss of control are warning signs that nonmedical use may have progressed into addiction.

Mental Health Effects

Studies suggest a link between cocaine misuse and mental health symptoms. Cocaine can increase anxiety, paranoia, agitation, and hallucinations. Cocaine-induced psychosis risk can increase with heavy use, sleep deprivation, high doses, or polysubstance use.

People may believe cocaine improves mental clarity or confidence, but these effects are brief and can impair judgment. Cocaine may create a false sense of confidence, increase impulsivity, and increase risky decisions.

Short-term effects of cocaine on mental state include:

• extreme happiness
• mental alertness
• hypersensitivity to sight, touch, or sound
• paranoia, or unreasonable distrust of others
• agitation
• impulsivity
• panic attacks
• mood swings
• insomnia
• depression after use

Cocaine misuse can worsen co-occurring mental health disorders such as anxiety, depression, bipolar disorder, post-traumatic stress disorder, and trauma-related symptoms. Therefore, dual diagnosis treatment can be important during recovery.

What Cocaine Does to Your Body

Cocaine can cause energy to rise quickly. This can increase:

• blood pressure
• heart rate
• body temperature
• breathing

These changes are linked to anxiety, which is why many people feel anxious after using cocaine. They can strain the cardiovascular system and may raise the risk of chest pain, heart attack, stroke, seizures, overheating, and sudden death.

Effects of Cocaine on the Heart

Cocaine has several effects on the heart. After use, it can increase heart rate and blood pressure. Cocaine can constrict blood vessels, reduce blood flow, and increase heart workload.

This strain can increase the risk of chest pain, heart attack, irregular heartbeat, stroke, blood clots, heart muscle inflammation, and sudden cardiac arrest. Heart problems can occur after occasional cocaine use, especially when other risk factors or substances are involved.

Cocaine may contribute to long-term cardiovascular problems by damaging blood vessels and increasing strain on the heart. These risks can worsen with repeated use, high doses, binge use, or polysubstance use.

Chest pain during or after cocaine use should be treated as a medical emergency. Severe headache, fainting, confusion, seizures, difficulty breathing, or loss of consciousness after cocaine use also requires urgent medical help.

Effects on the Respiratory System

Smoking crack cocaine can irritate and damage lung tissue. This can impair breathing and oxygen exchange. Lung-related problems linked to smoking crack cocaine are sometimes called “crack lung.”

Respiratory issues include:

• development or worsening of asthma
• pulmonary hypertension
• bronchiolitis
• bronchial spasms
• respiratory distress or respiratory failure
• chronic cough
• chest tightness
• wheezing
• lung inflammation
• higher respiratory infection risk

Respiratory complications can worsen when cocaine is combined with opioids, alcohol, or sedatives. Polysubstance use can make overdose symptoms less predictable and may increase fatal breathing problem risks.

Digestive Effects

Cocaine can affect the stomach and digestive system in short- and long-term ways. A short-term effect is nausea after use. Cocaine can reduce appetite, contributing to weight loss, poor nutrition, or malnutrition over time.

Other digestive issues include:

• bowel tissue damage
• nausea and vomiting
• inflamed large intestine
• tears or ulcers in the gut lining
• abdominal pain
• constipation
• poor nutrition
• dangerous weight loss

Cocaine constricts blood vessels, so it can reduce blood flow to parts of the digestive system. Reduced blood flow may contribute to serious digestive complications.

Cocaine Misuse and Overdose Risk

Cocaine overdose can occur when the drug causes toxic effects in the body and brain. Overdose risk increases when a person takes high doses, uses cocaine repeatedly during a binge, combines cocaine with other substances, or unknowingly takes fentanyl-contaminated cocaine.

Cocaine-involved overdose deaths have increased over the years. In 2018, more than 14,600 overdose deaths involved cocaine. Rapid emergency care can improve survival chances after an overdose.

Overdose symptoms can vary by person, especially when other drugs are involved. Emergency services should be contacted immediately when overdose is suspected or uncertainty remains.

Signs of cocaine overdose include:

• chest pain
• extreme agitation
• high fever
• seizures
• irregular heartbeat
• severe anxiety
• hallucinations
• confusion
• vomiting
• loss of consciousness

When fentanyl or another opioid may be involved, naloxone can help reverse opioid overdose symptoms while contacting emergency help. Naloxone does not reverse cocaine toxicity, so emergency medical care is still necessary.

Cocaine Withdrawal and Crash Symptoms

Cocaine withdrawal usually lacks the same acute medical dangers as alcohol or benzodiazepine withdrawal. However, it can still be highly distressing and can increase relapse risk.

Common cocaine withdrawal symptoms include:

• fatigue
• depression
• anxiety
• irritability
• sleep disturbances
• increased appetite
• difficulty concentrating
• low motivation
• strong cocaine cravings
• suicidal thoughts in severe cases

People may return to cocaine use to escape the crash or withdrawal symptoms. Professional support, therapy, relapse prevention planning, and dual diagnosis care can be key parts of treatment.
