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. Cocaine is rarely prescribed in modern medicine due to its high potential for abuse and significant risk of adverse effects; its use is now almost exclusively limited to health facilities for specific diagnostic procedures or surgeries. Although cocaine was once widely preferred for topical anesthesia, the search for replacement agents intensified due to rising costs, strict regulations, and its habit-forming potential. In 1986 an article in the Journal of the American Medical Association revealed that U.S. health food stores were selling dried coca leaves to be prepared as an infusion as “Health Inca Tea”.
Cocaine intoxication mirrors core traits of narcissism—both involve a dopamine-driven, compulsive drive for reward. Cocaine produces a spectrum of psychiatric symptoms including agitation, paranoia, anxiety, irritability, psychosis, hallucinations, delusions, violence, as well as suicidal and homicidal thinking. Cocaine use damages gray matter in brain regions critical for memory, attention, and emotion, leading to cognitive and behavioral impairments.
What Does It Mean To Have a Substance Abuse Problem?
The article stated that drinking two cups of the tea per day gave a mild stimulation, increased heart rate, and mood elevation, and the tea was essentially harmless. 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. Since 1961, the Single Convention on Narcotic Drugs has required countries to make recreational use of cocaine a crime.
Psychiatric symptoms
Depressive symptoms are linked to worse outcomes like longer depression, treatment, Cocaine and Alcohol Mix and risky behaviors. About 25% of adults with attention deficit hyperactivity disorder (ADHD) use cocaine, and 10% develop a cocaine use disorder during their lifetime. These mice self-administer cocaine at lower doses and display a greater propensity for relapse 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.
Cocaine (Crack)
A typical dose of snorted cocaine is between 30 and 70 milligrams. These unpleasant effects often make you want to use the drug again. The effects fade quickly, but how quickly depends on how you take the drug. How long does it take cocaine to kick in?
In 1994, the US 9th Circuit Court of Appeals cited findings that in Los Angeles, three out of four banknotes were tainted by cocaine or another illicit drug. When insufflating cocaine, absorption through the nasal membranes is approximately 30–60% Insufflation of cocaine also leads to the longest duration of its effects (60–90 minutes).
The dopamine transporter can no longer perform its reuptake function, and thus dopamine accumulates in the synaptic cleft. Cocaine binds tightly at the dopamine transporter forming a complex that blocks the transporter’s function. Cocaine increases levels of serotonin, norepinephrine, and dopamine in the synaptic cleft, leading to heightened post-synaptic activation, with dopamine contributing to euphoria and arousal, and the other monoamines enhancing additional effects.
What is cocaine (crack)?
Many issues play a role, including other mental health disorders, your background, and your environment. Drug use disorder, or addiction, is a complicated disease that involves changes to your brain structure. If you use a lot of cocaine, or the batch you use is stronger than you expect, you could overdose.

Others dissolve the drug in water and inject it with a needle. For this reason, you might hear the terms “crack” and “freebase” used interchangeably. It’s most often smoked in a pipe in the same way as crack. It gets its name because it crackles when heated up. In the 1970s, it became a popular recreational drug. It comes in powder form as well as solid chunks.
Cocaine Overdose
Withdrawal symptoms include disrupted sleep, irritability, depression, and reduced ability to experience pleasure (anhedonia). Cocaine can induce tolerance after a single dose, and repeated use frequently leads to the development of addiction and prolonged craving. With excessive dosage, tremors, convulsions, and increased body temperature are observed. Acute exposure may induce arrhythmia, including atrial fibrillation, supraventricular tachycardia, ventricular tachycardia, and ventricular fibrillation. This irritation leads to symptoms such as a runny nose, nasal congestion, and excessive or thickened mucus. Cocaine use has been linked to homicide, with up to 31% of homicide victims testing positive for the drug.
The increased concentration of dopamine in the synapse activates post-synaptic dopamine receptors, which makes the drug rewarding and promotes the compulsive use of cocaine. Family history is a known risk factor, as relatives of cocaine users have an increased likelihood of developing cocaine addiction. Repeated use raises the risk of developing “cocaine nose,” referring to severe nasal tissue damage from intranasal use, as well as “crack lung,” a condition involving lung tissue damage caused by inhaling crack cocaine. Aside from the toxic effects of cocaine, there is also the danger of circulatory emboli from the insoluble substances that may be used to cut the drug.
Cocaine Addiction Treatment
- Once the cocaine has reached the United States, Mexican traffickers sell it to American wholesale dealers.
- Another specialized protein called a transporter removes dopamine from the synapse to be recycled for further use.6
- Coca herbal infusion (also referred to as coca tea) is used in coca-leaf producing countries much as any herbal medicinal infusion would elsewhere in the world.
- Cocaine also may cause an unborn baby to have a stroke, irreversible brain injury, or a myocardial infarction.
- This therapy can also be used in conjunction with other treatments, thereby maximizing the benefits of both.38
The manufacturer says the torches only work on much purer forms of cocaine than are found on the street. A Newsbeat investigation found that “cocaine torches” used by UK police to detect cocaine use are ineffective on typical street cocaine, as independent lab tests showed they fail to make the drug fluoresce. This interest is partly motivated by the strong physiological effects of cocaine, but a further incentive was the unusual bicyclic structure of the molecule. As a tropane alkaloid, cocaine is a weak base and readily forms salts when combined with acids. In addition to this, cocaine has some target binding to the site of the κ-opioid receptor.
