Cocaine Definition, Uses & Addiction

Many people who are addicted to cocaine go through a phase called withdrawal when they first do this. Many people start to build a tolerance after their first use of cocaine. Another reason cocaine can lead to substance use disorder is that each time you use it, your body builds a tolerance. That same year, about 24,486 people died from an overdose that involved cocaine. With cocaine use disorder, you may become both physically and mentally dependent on the drug.

Dependence and withdrawal

This dopamine surge, simultaneous with the euphoric effects of the drug, teaches the brain that this reward is desirable and to seek it again. When people smoke cocaine (inhalation), they inhale its vapor or smoke into the lungs, where absorption into the bloodstream is almost as rapid as by injection. When snorted (intranasal use), cocaine powder is inhaled through the nostrils, where it is absorbed into the bloodstream through the nasal tissues. This form of cocaine is sometimes called crack, which refers to the crackling sound of the rock as it’s heated. Human studies also show that alcohol use increases the risk of transitioning from cocaine use to addiction.

Short-term effects

Recent research has also examined the use of prescription psychostimulants for cocaine dependence, following the Self-Medication Hypothesis. 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.

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. Regardless of the specific type of substance use disorder treatment, it is important that patients receive services that match all of their treatment needs.

Levamisole-induced necrosis syndrome (LINES) is a complication characterized by necrosis resulting from exposure to levamisole, a medication with immunomodulatory properties. Cocaine use can cause serious heart problems like sudden death, heart inflammation, arrhythmias, and heart attacks. Cocaine also may cause an unborn baby to have a stroke, irreversible brain injury, or a myocardial infarction. Cocaine-exposed babies also tend to have smaller heads, which generally reflect smaller brains. Cocaine base/crack can be smoked because it vaporizes with little or no decomposition at 98 °C (208 °F), which is below the boiling point of water.

Cocaine

• So you might keep taking the drug to prolong the good feelings and put off the unpleasant comedown.
• Cocaine intoxication mirrors core traits of narcissism—both involve a dopamine-driven, compulsive drive for reward.
• Recent research points to an important role of circadian mechanisms and clock genes in behavioral actions of cocaine.
• 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
• If you do attend rehab, continuing treatment afterward (aftercare) is important to help you avoid relapse.
• Every month, 150,000 people search for addiction or mental health treatment on Recovery.com.

The faster the drug is absorbed, the more intense the resulting high, but also the shorter its duration. Cocaine’s effects appear almost immediately after a single dose and typically disappear within a few minutes to an hour. The stress circuits of the brain are distinct from the reward pathway, but research indicates that there are important ways that they overlap. This reinforcement sets in motion the addiction cycle.8,9 Another specialized protein called a transporter removes dopamine from the synapse to be recycled for further use.6

Cocaine should not be used in individuals with a known allergy or hypersensitivity to the drug or any components of its topical formulation. This effectively destroys some of the cocaine and yields a sharp, acrid, and foul-tasting smoke. Powder cocaine (cocaine hydrochloride) must be heated to a high temperature to be smoked (about 197 °C), and considerable decomposition/burning occurs at these high temperatures. Crude cocaine preparation intermediates are marketed as cheaper alternatives to pure cocaine to local markets while the more expensive end product is exported to United States and European markets.

Using cocaine during pregnancy can cause problems for both the parent and the developing baby. There are about 750,000 cocaine-exposed pregnancies each year. Some research has suggested that cocaine damages the way immune cells work in your body, which could make HIV worse. Your chances of getting HIV, the virus that causes AIDS, are higher if you use cocaine. They can also add other drugs like amphetamine, fentanyl, heroin, or procaine. To make more money, dealers may “cut” the drug with other substances, like flour, baking soda, cornstarch, or talcum powder.

Coca leaves

• 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.
• Mexican cartels also operate labs in Central and South America to process coca leaves into cocaine.
• In addition, some parts of Europe, the United States, and Australia allow processed cocaine for medicinal uses only.
• Many people who are addicted to cocaine go through a phase called withdrawal when they first do this.

For example, cocaine acts by binding to the dopamine transporter, blocking the removal of dopamine from the synapse. The mechanisms of drug euphoria or reward are only somewhat understood but are now believed to involve several dispersed brain structures called “hedonic hotspots” that produce especially intense pleasure when activated simultaneously.4,5 Their activation involves several different chemical messengers including the body’s naturally occurring opioids. Drugs like cocaine powerfully activate reward and reinforcement mechanisms in the brain. Any route of administration can potentially lead to absorption of toxic amounts of cocaine, causing heart attacks, strokes, or seizures—all of which can result in sudden death.2,3

It’s absorbed through the tissues in your nasal passages and moves into your bloodstream. The traditional way to use cocaine is to sniff or snort it into your nostrils. Crack is stronger and more addictive than the powder form of the drug,

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.

Just as cocaine produces a brief high that temporarily enhances the sense of worth, narcissists rely on external admiration to feed an addiction to their self-esteem, resulting in a self-reinforcing feedback cycle. It also disrupts dopamine levels and blood flow, accelerating brain aging and causing long-term neurological harm. Brain imaging studies consistently report that individuals who misuse cocaine exhibit structural and functional abnormalities compared to non-users, supporting the classification of cocaine as a neurotoxic substance. In 2025, the Liberty House Clinic in the United Kingdom noted that chronic cocaine usage in fact had a higher risk of death than alcoholism. 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.

Crack Cocaine Process

Farmers are able to use unregulated and highly toxic pesticides due to the clandestine nature of drug production. Such areas are chosen for coca cultivation due to their remote locations, minimising chances of detection. The UNODC approximated that 97,622 hectares of primary forest were cleared for coca cultivation during 2001–2004 in the Andean region. Due to the illegal nature of coca production, farmers make little effort in soil conservation and sustainability practices as seen in the high mobility and short life of coca plots in Colombia. Many of these hazardous substances, such as solvents and acids, remain in the paste after processing.

How can I help someone who is addicted to cocaine?

These mice self-administer cocaine at lower doses and display a greater propensity for relapse Cocaine Withdrawal Guide after withdrawal ΔFosB also enhances sensitivity to reward by upregulating the AMPA receptor subunit GluR2 and downregulating the expression of dynorphin. Cocaine abuse can trigger addiction-related structural neuroplasticity in the human brain, although the permanence of such changes remains uncertain. According to the Global Burden of Disease Study, cocaine use is responsible for approximately 7,300 deaths annually.
