Although total synthesis is possible, it is complex and not used for production. Historically, cocaine was a standard topical medication used as a local anesthetic with intrinsic vasoconstrictor properties. However, its high abuse potential, adverse effects, and cost have limited its medical use and led to its replacement by alternative medicines. Street cocaine is commonly snorted, injected, or smoked as crack cocaine; its effects last up to 90 minutes depending on the route of administration. Pharmacologically, cocaine acts as a serotonin–norepinephrine–dopamine reuptake inhibitor (SNDRI), producing reinforcing effects such as euphoria, increased alertness, concentration, libido, and reduced fatigue and appetite. Cocaine has numerous adverse effects. Acute use can cause vasoconstriction, tachycardia, hypertension, hyperthermia, or seizures, while overdose may lead to stroke, heart attack, or sudden cardiac death. It also produces a spectrum of psychiatric symptoms, including agitation, paranoia, anxiety, irritability, psychosis, hallucinations, delusions, violence, Cocaine is a central nervous system (CNS) stimulant and tropane alkaloid, derived primarily from the leaves of two coca species native to South America: Erythroxylum coca and E. novogranatense.

Prenatal exposure poses risks to fetal development. Chronic use may result in cocaine dependence, withdrawal symptoms, neurotoxicity, and nasal damage, including cocaine-induced midline destructive lesions. While rarely used medically anymore, its accepted uses include serving as a topical local anesthetic for the upper respiratory tract and as an antihemorrhagic agent to stop bleeding in the mouth, throat, and nasal cavities. === Traditional medicine === ==== Coca leaves ==== It is legal to use coca leaves in the Andean Community, such as Peru and Bolivia, and Argentina, where they are chewed, consumed as tea, or sometimes incorporated into food products. Coca leaves are typically mixed with an alkaline substance (such as slaked lime) and chewed into a wad that is retained in the buccal pouch (mouth between gum and cheek, much the same as chewing tobacco is chewed) and sucked of its juices. Because it is not absorbed into the bloodstream in significant amounts when used this way, topical application does not produce the psychoactive effects associated with recreational cocaine use. ===== Topical anesthetic ===== Cocaine is sometimes used in otorhinolaryngology as a topical anesthetic and vasoconstrictor to help control pain and bleeding during surgery of the nose, mouth, throat, or lacrimal duct. It is also used for topical airway anaesthesia for procedures such as awake fibreoptic bronchoscopy or intubation. Although some absorption and systemic effects may occur, the use of cocaine as a topical anesthetic and vasoconstrictor is generally safe, rarely causing cardiovascular toxicity, glaucoma, and pupil dilation. Occasionally, cocaine is mixed with adrenaline and sodium bicarbonate and used topically for surgery, a formulation called Moffett's solution. It is occasionally used in surgeries involving the pharynx or nasopharynx to reduce pain, bleeding, and vocal cord spasm. Illicit cocaine is frequently adulterated with substances such as fentanyl, levamisole, or local anesthetics, increasing its toxicity. Concurrent use with alcohol produces cocaethylene, a metabolite that significantly increases the risk of sudden death. According to the Global Burden of Disease Study, cocaine use is responsible for approximately 7,300 deaths annually. Cocaine abuse can trigger addiction-related structural neuroplasticity in the human brain, although the permanence of such changes remains uncertain. Family history is a known risk factor, as relatives of cocaine users have an increased likelihood of developing cocaine addiction. Numerous medications have been investigated for use in cocaine dependence, but as of 2015, none of them were considered to be effective. Drugs which help to re-stabilize the glutamate system such as N-acetylcysteine have been proposed for the treatment of addiction to cocaine, nicotine, and alcohol. However, none have sufficient evidence or regulatory approval for routine clinical use, so psychosocial interventions remain the mainstay of treatment. ==== Cocaine nose ==== "Cocaine nose" or "coke nose" are
