Rapid onset. Actual dosage may vary significantly with product purity.
Effects vary widely by individual, dose, and context.
The physical effects of cocaine can be broken down into several components which progressively intensify proportional to dosage.
The cognitive effects of cocaine can be broken down into several components which progressively intensify proportional to dosage. The general head space of cocaine is described by many as one of extreme mental stimulation, increased focus, and powerful euphoria. It contains a large number of typical stimulant cognitive effects. Although negative side effects are usually mild at low to moderate dosages, they become increasingly likely to manifest themselves with higher amounts or extended usage. This particularly holds true during the offset of the experience.
These combinations are considered extremely harmful and should always be avoided. Reactions to these drugs taken in combination are highly unpredictable and have a potential to cause death.
There is considerable risk of physical harm when taking these combinations, they should be avoided where possible.
These combinations are not usually physically harmful, but may produce undesirable effects, such as physical discomfort or overstimulation. Extreme use may cause physical health issues. Synergistic effects may be unpredictable. Care should be taken when choosing to use this combination.
Cocaine has a high potential for psychological addiction and compulsive redosing. Its effect on dopamine levels is primarily responsible for its addictive properties. Craving can be triggered rapidly by environmental cues, situations, or memories associated with use. Tolerance can develop after a single dose, and repeated use frequently leads to addiction and prolonged craving.
Physical dependence develops after even brief periods of regular use. Withdrawal symptoms include disrupted sleep, irritability, depression, fatigue, increased appetite, and reduced ability to experience pleasure. While uncomfortable, cocaine withdrawal is not life-threatening. Depressive withdrawal symptoms are associated with worse treatment outcomes and increased risk of relapse.
The estimated minimum lethal dose is 1.2 grams according to the European Union Drugs Agency. However, sensitive individuals have died from as little as 30 milligrams applied to mucous membranes. In contrast, tolerant individuals may use up to 5 grams per day. Overdose can cause acute myocardial infarction, respiratory failure, stroke, cerebral hemorrhage, and sudden cardiac arrest. There is no specific antidote for cocaine overdose.

Cocaine is cardiotoxic and can cause serious heart problems including arrhythmias, heart inflammation, and myocardial infarction at both acute high doses and with chronic use. Long-term use accelerates atherosclerosis and increases blood clot formation risk.
Both acute and chronic cocaine use can lead to significant reductions in cerebral blood flow, cognitive deficits, and increased risk of hemorrhagic and ischemic strokes. Gray matter damage occurs in regions critical for memory, attention, and emotion.
Chronic intranasal use causes progressive damage to nasal mucosa, septum, and surrounding structures; approximately 30% of regular users and 47% of daily users experience nasal irritation, crusting, and frequent nosebleeds. Severe cases progress to cocaine-induced midline destructive lesions with erosion of the palate and sinuses.
Acute hepatotoxicity can occur with overdose, typically due to toxic metabolites; most cases resolve quickly but fatal outcomes from multiple organ dysfunction are possible.
Renal impairment can occur as part of cocaine toxicity syndrome, particularly in overdose situations involving rhabdomyolysis and hyperthermia.
Rhabdomyolysis can occur with acute cocaine toxicity, particularly at high doses or during prolonged physical activity while intoxicated.
Chronic use is associated with general weakening of immune function. Levamisole-adulterated cocaine causes severe agranulocytosis in a subset of users, with skin necrosis affecting the ears, face, and extremities.
More than half of people who abuse cocaine report experiencing psychotic symptoms at some point. Typical symptoms include paranoid delusions of being followed or watched, accompanied by supporting hallucinations. Delusional parasitosis with formication, commonly called 'cocaine bugs,' is a fairly common symptom. Cocaine-induced psychosis shows sensitization, meaning psychosis becomes more severe with repeated intermittent use.
Cocaine can cause convulsions and reduces seizure threshold. Seizures are more commonly associated with overdose situations and high doses but can occur with acute exposure. Overdose may cause seizures alongside abnormally high body temperature and marked blood pressure elevation.
Coca chewing dates back at least 8,000 years in South America, making it one of the oldest known psychoactive plant practices. The leaves were integral to Andean civilizations including the ancient Wari and Inca cultures, where they served both stimulant and medicinal purposes. Traditional…

Controlled drug requiring prescription for medical use. In Western Australia, the Misuse of Drugs Act 1981 specifies threshold quantities: 4.0 grams determines court of trial jurisdiction, 2.0 grams creates presumption of intent to supply, and 28.0 grams constitutes trafficking.
Cocaine hydrochloride pharmaceutical preparations are available for legitimate medical purposes. Topical solutions have been marketed since the 1990s for clinical applications. Recreational possession, production, and distribution remain prohibited.
Traditional coca leaf consumption is permitted, including chewing and preparation as tea. The National Coca Company, a state enterprise, produces and sells coca-based teas and medicinal products, and exports leaves internationally for pharmaceutical use. However, production, sale, and recreational consumption of refined cocaine are illegal.
Coca cultivation for traditional indigenous consumption is protected under the Bolivian Cato accord, which specifies allowable annual yields for farmers. Coca leaves may be chewed or consumed as tea. Production, distribution, and consumption of refined cocaine remain criminal offenses.
Cultivation of coca leaf is permitted for traditional consumption by indigenous populations. Manufacturing, trafficking, and recreational use of cocaine are prohibited under national drug control legislation.
Classified as having high abuse potential with accepted medical uses. The 1970 Controlled Substances Act regulates manufacture, importation, possession, and distribution. Medical cocaine products remain available for topical anesthesia, including Goprelto (approved December 2017) and Numbrino (approved January 2020). Historical legislation includes the Harrison Narcotics Tax Act of 1914, which established licensing requirements, and the Jones-Miller Act of 1922, which imposed manufacturing restrictions. The Anti-Drug Abuse Act of 1986 created significant sentencing disparities between powder and crack cocaine.
