Coca (also referred to as ‘Bolivian’ or ‘Huanuco’ coca) that the majority of cocaine supply is extracted [21,22]. The coca plant presents large, thick, dark green leaves with an elliptical shape and a somewhat sharp apex, and has small red fruits [23]. Circa 18 different alkaloids can be found in the leaves of the coca plant, such as cinnamoylcocaine, tropacocaine, methylecgonine, benzoylecgonine (BE) and pseudotropine—all of these are significantly less euphoric and less toxic than cocaine (Figure 1) [21,22]. Sudden death with the first use of cocaine is also a known possibility.
7. Effects and Toxicity of Cocaine
Therapeutic communities or residential programs with stays of several months are also on offer for treatment for those who abuse cocaine. Therapeutic communities focus on the resocialization of the individual and can include on-site vocational rehabilitation and an array of other supportive services. Binge cocaine use, in which the drug is taken repeatedly and at increasingly higher doses, leads to a state of increasing irritability, restlessness, and paranoia. It may result in a full-blown paranoid psychosis in which the individual loses touch with reality and experiences auditory hallucinations. The scientists believe that the basal ganglia were already enlarged before the addiction began.

Mark S. Gold, M.D., is a pioneering researcher, professor, and chairman of psychiatry at Yale, the University of Florida, and Washington University in St Louis. His theories have changed the field, stimulated additional research, and led to new understanding and treatments for opioid use disorders, cocaine use disorders, overeating, smoking, and depression. Although Dr. Dave does not think marijuana should be criminalized, his views toward the drug have considerably shifted since the 1960s, slowly over the years. He says, “More emphasis needs to be placed on preventive treatment, particularly in youth. In some cases, even after receiving the administration of oxygen, aspirin, benzodiazepines, and nitroglycerin, the subjects still have chest pain. In these instances, administration of the non-selective α-adrenoceptor antagonist phentolamine is recommended to induce vasodilation, as β-adrenergic blockers are not useful in treating this clinical manifestation [2,96].
- An estimated 27% of children who spend 3 or more hours a day on social media exhibit symptoms of poor mental health.
- Researchers have attempted to measure the addictiveness of cocaine and other drugs.
- Additionally, a delay in ventricular depolarization ensues, ultimately causing a decrease of the left ventricular function [99].
- As with any disorder, treatment strategies need to assess the biological, social, emotional, and pharmacological aspects of the individual’s drug abuse.
- Cocaine, especially crack cocaine, is strongly addictive for several reasons.
- NAc nerve cells make five types of dopamine receptors; drugs that affect the functioning of one or more of them could, in theory, produce a palliative effect on cocaine addiction.

Injecting the drug can increase your risk of a serious skin infection, such as a bacterial staphylococcus infection. Cellulitis (a severe type of skin infection) and necrotizing fasciitis (destruction of the infected tissue), and a systemic infection can develop as well. There are a number of complications of cocaine addiction, and they can differ depending on your method of using the drug. According to the National Institute on Drug Abuse, around 68% of people seeking cocaine treatment regularly use crack cocaine.
When the user finally stops, they will often sleep for an abnormally long time, and become irritable, anxious, and depressed, which will drive them to repeat this behavior. However, snorting the drug still causes an intense and rapidly-developing addiction. The high from cocaine is short-lived and makes an individual feel extremely good before it wears off, at which point intense drug cravings begin, as does depression and an increasing inability to experience pleasure without drugs.
There are quite a few known interactions between cocaine and other substances, including over-the-counter (OTC) and prescription medications and other drugs. More people are admitted to emergency rooms for cocaine-related issues than any other illicit substance. It’s not a https://sober-home.org/ sign of weakness, bad judgement or other personal characteristics. The best way to support someone coping with addiction is to encourage them to find help. It’s also important to remember cocaine use often has a ripple effect, putting stress and strain on relationships.
A subject who drank a cup of the Peruvian (4.14 mg cocaine) or Bolivian teas (4.29 mg cocaine) had, in their urine, a BE concentration of 3940 ng/mL and 4979 ng/mL, 10 and 3.5 h after ingestion, respectively [58]. Crack cocaine is the smokable form of the drug and comes as crystals known as rocks or stones. Crack and cocaine powder can be injected but doing this is linked to many harmful effects. Cocaine produces dopamine buildup wherever the brain has dopamine transporters. Dopamine-responsive cells are highly concentrated in this system, which controls emotional responses and links them with memories. Cocaine is a highly addictive substance that sends signals to the user, making them feel that they must continue using it to feel happy.
When snorted (intranasal use), cocaine powder is inhaled through the nostrils, where it is absorbed into the bloodstream through the nasal tissues. Dissolving cocaine in water and injecting it (intravenous use) releases the drug directly into the bloodstream and heightens the intensity of its effects. 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. The impairment of these cognitive centers can lead to the compulsive use of cocaine—with little to no regard for the consequences.
Taken in combination, the two drugs are converted by the body to cocaethylene, which has a prolonged duration of action in the brain and is more toxic than either drug alone. The mixture of cocaine and alcohol is the most common two-drug combination that https://sober-home.org/comorbid-post-traumatic-stress-disorder-in-alcohol/ results in drug-related death. The team scanned the brains of 120 individuals, half of whom were addicted to cocaine. Results showed a widespread loss of gray matter among cocaine users. The loss was greater among those who had used the drug for longer.
This can make it very difficult to quit using without professional assistance. This combination of brain-changing effects can evolve into the user focusing on cocaine instead of relationships, food, or other natural rewards. With ongoing use, the reward pathway becomes dysregulated, resulting in decreased responsiveness to natural reinforcers such as food. In addition, the stress response becomes heightened, leading to irritability and negative moods when not using cocaine. Animal research suggests the orbitofrontal cortex sustains some level of damage over long periods of cocaine use.
Soccer, believes there are holistic ways football can help reduce the need for substances. One coach recalls witnessing senior players in their thirties celebrate two years of being snus-free, reminded of the landmark by the rehab app on their phone. “I also wonder whether it is because they are obsessive people,” says one head of performance with experience working across Championship and Premier League clubs. “These young men need support in understanding their emotions, being self-aware and able to self-regulate.
Hallmark physiological effects of cocaine include those of the cardiovascular nature, such as vasoconstriction, tachycardia, and hypertension. When cocaine is consumed, an exacerbated dopaminergic activity along the mesocorticolimbic pathways occurs. Neurons from these pathways are located in the ventral tegmental area and project to other brain locations, including the nucleus accumbens [78]. This could explain why the drug has such an addictive potential, since it is well acknowledged that the nucleus accumbens may have an important role in the rewarding and addictive properties of cocaine and other drugs [79]. However, it should be mentioned that cocaine’s capacity to increase serotoninergic activity (which may induce seizures) could also contribute to the drug’s addictive potential [80,81].
Get professional help from an online addiction and mental health counselor from BetterHelp. Research indicates that cocaine use can significantly increase the risk of a heart attack or stroke. The basal ganglia, a part of the brain that houses the reward system, was found to be larger among individuals who were dependent on cocaine.
Furthermore, cocaine can stimulate a cascade of reactions, including caspase-3 activation and cytochrome c release, leading to hepatocellular apoptosis [62]. Huestis et al. carried out a study resorting to 6 human subjects, where they investigated the urinary excretion pattern of cocaine and of some metabolites (BE, EME, m-OH-BE, p-OH-BE, NBE and EC), following smoking [33]. This study demonstrated a dose-dependent increase of the Maximum Concentration (Cmax) of all analytes, while the parameter Time-to-Maximum (Tmax) failed to show direct proportionality. Among the metabolites, EME presented the longest detection time (up to 164 h after a 40 mg dose).
This first case was consistent with earlier and later studies [119,120,121]. The hallmark hepatic lesion following cocaine use is hepatocellular necrosis, which was also demonstrated in animal studies [83,122]. Other pathological characteristics of cocaine-induced hepatic injury include increased infiltration with fatty acids, increased blood aspartate aminotransferase levels and pernicious conjugates of reactive cocaine metabolites with cellular macromolecules [83]. The vasoconstrictive properties of cocaine also affect the respiratory system, particularly at the nasal level for intranasal administration. The cocaine-induced midline destructive lesion occurs because of the continuous vasoconstriction, which the vessels in the nasal lining mucosa are subjected to when users ‘snort’ cocaine [3]. Prolonged vasoconstriction of the tissue leads to the development of ischemia and, in conjunction with the inflammatory process, ultimately results in the perforation of the nasal septa [3].
This center artificially “rewards” the person after cocaine use with pleasure and euphoria. Cocaine works by blocking the decrease of dopamine in the body, leading to increased amounts. Increased dopamine levels activate the part of the brain that is referred to as the reward center, the ventral tegmental area (VTA). The brain of someone addicted to cocaine begins craving the drug shortly after use begins, and it doesn’t take long for them to need to use cocaine just to feel normal.
There is great risk regardless of the method of use, and it is possible to overdose fatally. Compulsive cocaine use may develop even more rapidly if the substance is smoked rather than snorted. Smoking allows extremely high doses of cocaine to reach the brain very quickly and brings an intense and immediate high.
Another reason cocaine can lead to substance use disorder is that each time you use it, your body builds a tolerance. Research suggests that certain communities may be more prone to using drugs, including cocaine. For example, those who identify as LGBTQ are more than twice as likely to use illicit drugs as heterosexual people. LGBTQ adults are also more than twice as likely to have a substance use disorder. At cocaine rehab, people can receive support and evidence-based treatment that matches their specific needs.
To diagnose a cocaine addiction, your doctor will discuss your current usage and health history. And they will try to determine the degree of your dependence and will suggest treatment options. Behavioral treatment includes psychotherapy and other psychosocial interventions. These approaches help to maintain abstinence from cocaine after detox. Often, behavioral therapy is initiated right when you begin detox, or even before you stop using the drug.
They further regulate the amount of dopamine available to stimulate the receptors by pulling some previously released dopamine molecules back into themselves. Dopamine originates in a set of brain cells, called dopaminergic (dopamine-making) cells, that manufacture dopamine molecules and launch them into their surroundings. Some of the free-floating dopamine molecules latch onto receptor proteins on neighboring (receiving) cells.
