Cocaine haptens are chemically modified derivatives of cocaine that retain key immunogenic features, allowing them to be attached to carrier proteins such as keyhole limpet hemocyanin or bovine serum albumin. It provides a highly reliable, conservative record of cocaine movements and interdiction efforts, revealing that despite large seizures, interdiction captures only a small fraction of trafficking events and has minimal impact on U.S. cocaine prices. One of the major implications of cocaine production is deforestation as large areas of forest are cleared for coca cultivation. The environmental destruction caused by the production of cocaine has been well documented, with reports made the UN and other government bodies. Most of the world’s cocaine is produced in South America, particularly in the Andean region. This combination of affordability, accessibility, and toxicity makes cocaine paste particularly damaging to vulnerable populations in cocaine-producing regions.
Cocaine vaccines
Ask a healthcare provider about programs and services for people affected by another person’s cocaine use. Over time, using cocaine may increase the risk of medical issues, some of which may be life-threatening. One study showed 15% of people who used cocaine became addicted to the drug within 10 years. As people keep on using cocaine, their brains get used to the huge overstimulation and they need stronger, more frequent doses. But that cocaine-driven dopamine release or rush fades quickly, leaving them wanting more of those feelings — and the drug.
Movies present examples and information that support the development of coping skills; quizzes, games, and homework assignments reinforce the lessons and provide opportunities to practice skills.43-45 Studies have shown that adding CBT4CBT to weekly counseling boosted abstinence43 and increased treatment success rates up to 6 months after treatment.44 Cognitive-behavioral therapy (CBT) is another effective approach for treating cocaine addiction. Research indicates that CM benefits diverse populations of people who use cocaine.
How Common Is Cocaine Use?
Information provided by NIDA is not a substitute for professional medical care or legal consultation. NIDA is a biomedical research organization and does not provide personalized medical advice, treatment, counseling, or legal consultation. Once inpatient treatment ends, ongoing support—also called aftercare—can help people avoid recurrence. For example, an unemployed patient would benefit from vocational rehabilitation or career counseling along with addiction treatment.
- Learn about causes, symptoms, risks, and treatment for cocaine withdrawal.
- The UNODC approximated that 97,622 hectares of primary forest were cleared for coca cultivation during 2001–2004 in the Andean region.
- Cocaine is made from leaves of the coca plant.
- But with the proper support, many people are able to overcome a crack cocaine addiction.
- Persons with regular or problematic use of cocaine have a significantly higher mortality rate, and are specifically at higher risk of traumatic deaths and deaths attributable to infectious disease.
How does cocaine work in the brain?
This discrepancy is not shared with other dopamine reuptake inhibitors like bupropion, sibutramine, mazindol or tesofensine, which have similar or higher potencies than cocaine as dopamine reuptake inhibitors. Cocaine’s binding properties are such that it attaches so this hydrogen bond will not form and is blocked from formation due to the tightly locked orientation of the cocaine molecule. The 5-HT2 receptor (particularly the subtypes 5-HT2A, 5-HT2B and 5-HT2C) are involved in the locomotor-activating effects of cocaine. The most extensively studied effect of cocaine on the central nervous system is the blockade of the dopamine transporter protein.
How Is Recovery.com Different?
A 2021 study found that cocaine use disorder impairs emotion recognition, especially for happiness and fear, with improvement after long-term abstinence. A 2020 study found that men with cocaine use disorder have greater difficulty identifying emotional expression in female faces, affecting relationships and suggesting a target for intervention. In 1989 Fulton County, 40% of homicide victims had cocaine metabolites, especially Black and firearm victims.
Psychiatric symptoms
Stress can contribute to cocaine recurrence, and cocaine use disorders frequently co-occur with stress-related disorders. This pathway originates in a region of the midbrain called the ventral tegmental area and projects to other brain areas including the nucleus accumbens, where one of the brain’s hedonic hotspots is also located.6 Besides reward and reinforcement, this circuit also regulates emotions and motivation.7 Cocaine is a Schedule II drug, which means that it has high potential for misuse but can be administered by a doctor for medical uses, such as local anesthesia for some eye, ear, and throat surgeries. It is made from the leaves of the coca plant (Erythroxylon coca), which is native to South America.1
Cocaine and its major metabolites may be quantified in blood, plasma, or urine to monitor for use, confirm a diagnosis of poisoning, or assist in the forensic investigation of a traffic or other criminal violation or sudden death. Cocaine overdose may result in hyperthermia as stimulation and increased muscular activity cause greater heat production. When nasal damage is too severe for reconstruction, a nose prosthesis may be used to restore appearance and quality of life. Repair may involve rhinoplasty, which includes creating a new internal lining with nasolabial flaps and restoring support with costal cartilage grafts. Chronic intranasal usage can degrade the cartilage separating the nostrils (the septum nasi), leading eventually to its complete disappearance. Cocaine use should be considered as a potential cause of persistent or unexplained rhinitis, including in adolescent patients.
Long-term effects
The euphoric effects of sniffing cocaine are relatively transitory and wear off after about 30 minutes. In other cultures the active alkaloid is chemically extracted from coca leaves and is converted into the hydrochloric salt of cocaine, cocaine hydrochloride. More importantly, cocaine when ingested in small amounts produces feelings of well-being and euphoria, along with a decreased appetite, relief from fatigue, and increased mental alertness.
Over time, cocaine use may change other brain functions. The 2021 (U.S.) National Survey on Drug Use and Health (NSDUH) concludes 4.8 million people age 12 and older used cocaine in 2020. People use crack cocaine by heating it in a glass pipe or adding it to marijuana or tobacco. More commonly, people use cocaine to boost feelings like being energized, happy and alert. Cocaine is a powerful stimulant drug that’s extracted and processed from coca plant leaves in South America.
Furthermore, a similar response-occupancy discrepancy has been observed with methylphenidate, which also stabilizes the dopamine transporter in an open outward-facing conformation. Re-administering cocaine beyond this threshold does not significantly increase DAT occupancy but still results in an increase of euphoria which cannot be explained by reuptake inhibition alone. Conflicting findings have challenged the widely accepted view that cocaine functions solely as a reuptake inhibitor. Research studies have suggested that the affinity for the transporter is not what is involved in the habituation of the substance so much as the conformation and binding properties to where and how on the transporter the molecule binds. An overabundance of 5-HT3 receptors is reported in cocaine-conditioned rats, though 5-HT3’s role is unclear. The dopamine transporter can no longer perform its reuptake function, and thus dopamine accumulates in the synaptic cleft.
- 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.
- Many of these hazardous substances, such as solvents and acids, remain in the paste after processing.
- The traditional way to use cocaine is to sniff or snort it into your nostrils.
- Countries that transport cocaine across national lines, such as Mexico or Caribbean countries including Haiti, the Bahamas, and the Dominican Republic, are also big players.4,5,11,12,13,15
- The 5-HT2 receptor (particularly the subtypes 5-HT2A, 5-HT2B and 5-HT2C) are involved in the locomotor-activating effects of cocaine.
- It provides a highly reliable, conservative record of cocaine movements and interdiction efforts, revealing that despite large seizures, interdiction captures only a small fraction of trafficking events and has minimal impact on U.S. cocaine prices.
This syndrome is marked by skin necrosis, often affecting areas such as the ears, face, and extremities, and is thought to result from levamisole’s effects on blood vessels and the immune system. In the body, levamisole is converted into aminorex, a substance with amphetamine-like stimulant effects and a long duration of action. Before trafficking to the United States, the cocaine is frequently adulterated with levamisole. It can also become a serious risk at high doses due to cocaine’s blocking effect on cardiac sodium channels. Cocaine as a drug has a low molecular weight and high water and lipid solubility which enables it to cross the placenta and fetal blood-brain barrier.
The FDA hasn’t approved any medicine to treat cocaine addiction. Counseling and other types of therapy are the most common treatments for cocaine use disorder. Many people who are addicted to cocaine go through a phase called withdrawal when they first do this.

Read about the history of cocaine in the U.S., from its early use in medicine to the crack cocaine epidemic in the late 20th century. Learn about the signs of cocaine addiction, how to help someone with cocaine addiction, and how to pursue the path to recovery. Mexican cartels also operate labs in Central and South America to process coca leaves into cocaine. But crackdowns on the Caribbean route and on Colombian cartels led to Mexican cartels playing a larger role in trafficking cocaine to North America.
Depression is modestly linked to current drug use in cocaine users but does not clearly predict treatment participation or future use. Research has shown that both acute and chronic cocaine use can lead to significant reductions in cerebral blood flow, disrupt neurovascular interactions, and impair brain function. Cocaine- and levamisole-induced vasculitis (CLIV) is often used as an umbrella term for the vasculitic and necrotic complications seen with levamisole-adulterated cocaine, including both LINES and CLAAS.
