Detailed information on how cocaine affects the body and mind, short-term and long-term risks, overdose, and treatment options.
Pharmacology
Cocaine inhibits the reuptake of dopamine, norepinephrine, and serotonin. It also blocks voltage-gated sodium channels, producing local anesthetic effects.
The result is euphoria, increased energy, reduced appetite, dilated pupils, elevated heart rate, and increased blood pressure.
Dopamine and reward
Elevated dopamine in the mesolimbic pathway reinforces repeated use, contributing to dependence.
Cardiovascular stress
Norepinephrine reuptake inhibition causes vasoconstriction, tachycardia, and hypertension, increasing myocardial oxygen demand.
Local anesthesia
Sodium channel blockade numbs mucous membranes, a property exploited in surgery and mimicked by adulterants.
Short-term effects
Desired effects include euphoria, talkativeness, alertness, and confidence. Adverse effects include anxiety, agitation, panic, paranoia, chest pain, nausea, and headache.
Desired effects
Users report increased energy, sociability, mental clarity, and heightened sensory awareness.
Adverse effects
Higher doses can cause anxiety, panic, paranoia, dizziness, tremor, chest pain, and arrhythmia.
Route differences
Smoking and injection produce the fastest onset and highest overdose risk. Snorting has a slower onset but can damage nasal tissues.
Long-term health risks
Chronic use damages the cardiovascular, respiratory, neurological, and psychiatric systems. Dependence, tolerance, and withdrawal are common with repeated use.
Cardiovascular
Hypertension, cardiomyopathy, aortic dissection, stroke, and myocardial infarction can occur, sometimes in young users.
Respiratory
Smoking crack or freebase can cause lung injury, chronic cough, pneumothorax, and respiratory failure.
Nasal and oral
Chronic snorting can perforate the nasal septum, cause sinusitis, and lead to loss of smell.
Infectious disease
Injection use raises risks of HIV, hepatitis C, endocarditis, abscesses, and septic emboli.
Mental health
Chronic use is associated with depression, anxiety, psychosis, and suicidal ideation.
Overdose and toxicity
Signs of overdose include severe chest pain, seizures, extreme agitation, hyperthermia, irregular heartbeat, and loss of consciousness. Combining cocaine with alcohol forms cocaethylene, which is more cardiotoxic.
Emergency response
Call emergency services, place unconscious people in the recovery position, and monitor breathing. Naloxone reverses opioids but not cocaine toxicity, though it may help if fentanyl is present.
Polysubstance risk
Mixing cocaine with alcohol, opioids, benzodiazepines, or other stimulants dramatically increases overdose risk.
Treatment
Effective treatments for cocaine use disorder include contingency management, cognitive behavioral therapy, motivational interviewing, and community reinforcement. No medication is currently FDA-approved specifically for cocaine addiction, though several are under investigation.
Harm reduction
Strategies include drug checking, fentanyl test strips, naloxone access, supervised consumption, sterile injection equipment, and stimulant-specific treatment services.
