Cocaine is a powerful recreational drug that creates intense feelings of euphoria, happiness, and alertness. It has gained infamy over the years due to its association with popular culture and celebrity abuse. Cocaine continues to be a controversial drug due to its powerful effects, contentious history, and addictive nature.
Read on to discover some unlikely health benefits and learn more about the dangerous effects of cocaine.
NOTE: Selfhacked does not support the use of cocaine, even though it may have some benefits. We feel the negatives far outweigh any of the positives.
What is Cocaine?
In spite of its recent notoriety, cocaine has a documented history of use by the Amara Indians of Peru. This tribe has “used cocaine” for thousands of years by chewing the leaves of the coca plant .
This kind of use has fewer adverse effects, presumably due to the low concentration of the active component in the leaves and the laborious act of extracting cocaine by chewing the leaves .
Modern Use and Abuse
However, everything changed in 1859 when German chemist Albert Niemann purified cocaine .
Around the end of 1884, cocaine started gaining publicity and scientific interest. Sigmund Freud praised the drug in his famous Cocaine Papers describing its therapeutic properties in relieving depression and anxiety .
Following Freud’s publications, Carl Koller discovered the anesthetic properties of cocaine on the human eye. Purified cocaine became commercially available when Merck started refining and producing it [8, 5].
Without regulatory restrictions, cocaine was initially sold as a therapeutic and consumable product. However, the Harrison Narcotics Act of 1914 in the US banned the distribution of cocaine due to its widespread abuse and addiction [6, 9].
Despite regulatory restrictions, the drug is still sold and used illegally around the world. According to a United Nations report, around 18.3 million people used cocaine in 2014 .
Pure cocaine is a white crystal powder that can be snorted, smoked, or injected. It’s called “crack” when smoked (freebase form); street names include coke, flake, snow, and powder .
How It Works
Cocaine is highly addictive and produces a feeling of euphoria by causing a buildup of dopamine in the brain’s pleasure center (the limbic system) .
Desired Short-Term Effects Of Cocaine
- Increased energy, alertness, or sociability
- Inflated self-esteem
- Decreased fatigue
3 Medical Uses Of Cocaine
Besides cocaine, the coca leaves contain essential nutrients such as vitamins and minerals and have many health benefits .
However, refined cocaine is a very powerful stimulant that has a limited number of health benefits. These health benefits do NOT counteract the addictiveness and side effects of cocaine.
1) Produces Topical Anesthesia For Surgical Procedures
The numbing properties of cocaine make it an ideal anesthetic for surgical practices .
When combined with other compounds (tetracaine and adrenaline), it can be used as a topical anesthetic for minor facial and scalp lacerations .
2) Helps Wound Healing
3) Might Help With Weight Loss
Cocaine decreases storage and increases the breakdown of fat through its effects on the brain .
However, given the adverse effects of cocaine consumption, its effects on weight loss are often overlooked.
5 Side Effects/Risks Of Cocaine
Cocaine is a powerful drug that has both short and long-term effects.
How It Works
Mitochondria are the energy generators of the cell. As shown by cell-based studies, cocaine can accumulate inside the cell and damage the functional and structural integrity of mitochondria, disrupting cellular energy production and resulting in cell death .
Also, animal studies showed that cocaine could produce oxidative stress in cells and alter mitochondrial genes .
In the heart, this oxidative stress leads to toxicity and cell death, as observed in human cocaine overdose .
1) Psychological And Mood Disorders
Cocaine can significantly impact the user’s mood and psychological state. Cocaine users have reported a wide range of adverse psychological effects including anxiety, depression, mood swings, paranoia, and panic attacks .
Chronic cocaine use can cause symptoms of delirium and aggression .
Although rare, higher doses can cause hallucinations or false sensory perceptions .
Abstinence from cocaine use can create withdrawal symptoms like mood disturbances and cravings .
2) Sleep Disorders
Cocaine can impair wakefulness and sleep cycles due to chemical changes in the brain .
More specifically, cocaine can lead to a reduction in REM (rapid eye movement) sleep, which has been associated with depression .
Consequently, sleep disturbances and insomnia can cause depression and even lead to suicide .
3) Cognitive Impairment
Magnetic resonance imaging (MRI) studies have shown that cocaine decreases the activity in many regions of the brain .
It reduced memory and learning performance, and these effects lasted for up to 4 weeks of abstinence in 56 chronic cocaine users .
4) Respiratory Complications
The acute respiratory symptoms of smoking cocaine include coughing with sputum, chest pain, shortness of breath, coughing of blood (hemoptysis), and worsening of asthmatic symptoms .
Prolonged exposure to cocaine can lead to obstructive pulmonary disease and fever. Other reports indicate that inhalation of (freebase) cocaine could directly damage the pulmonary gas exchange surface [69, 70].
5) Heart Complications
Cocaine causes short-term physical effects such as increased blood pressure, constricted blood vessels, and increased heart rate. By increasing heart rate and blood pressure, cocaine increases the heart’s oxygen demand [49, 71, 72].
A combination of these effects can damage the blood vessels .
Cocaine use is also associated with hypertension, irregular heart rates, reduced blood flow to the heart, heart attacks, and sudden heart death. The risk of an acute heart attack is increased 24 times after cocaine use in relatively low-risk individuals [74, 75, 76].
An autopsy performed on 40 subjects who were positive for cocaine revealed that cocaine use leads to inflammation and damage to the heart muscle .
Signs of Cocaine Use
Warning signs of chronic cocaine use include:
- Redness or inflammation of the eyes 
- Dilated pupils 
- Runny or bleeding nose with swollen, inflamed mucosa 
- Difficulties standing or sitting 
- Behavioral changes like repetition and ritualistic behaviors 
- Emotional changes 
- Incoherent speech 
Consumption of high doses of cocaine can result in overdose or poisoning. The symptoms of cocaine overdose include :
- Psychosis, agitation, or delirium
- Seizures or stroke
- Heart problems (irregular heart rate and increased blood pressure)
- Respiratory problems
- High body temperature
How To Reduce Adverse Effects
Depletion of dopamine in cocaine users leads to depression, decreased cognitive function, and fatigue. Administration L-tyrosine helps to increase dopamine concentrations in the brain (L-tyrosine>Dopa>Dopamine) .
Tyrosine can come from nutritional supplements or food sources such as chicken, turkey, soy products, or fish .
However, increasing tyrosine may potentially mitigate only a fraction of cocaine adverse effects, and it doesn’t make cocaine use any safer .
Treatment Of Addiction: Cognitive-Behavioral Approach
There are many different strategies or treatments for cocaine addiction. One approach is through cognitive-behavioral therapy (CBT). CBT utilizes several important tasks to combat cocaine addiction, including [87, 88]:
- Maintaining motivation to abstain from drug use by emphasizing the gains/losses through drug use 
- Teaching effective coping skills 
- Identifying and reducing habits associated with drug use 
- Fostering management and tolerance of withdrawal effects such as depression or anger 
- Building and using effective social support and environment to decrease the risks of addiction

Cocaine comes from the leaves of the coca plant. Native Americans have been chewing coca leaves for ages, which contain essential nutrients and tiny amounts of cocaine. Unlike pure cocaine, they improve digestion and alertness with no major side effects.
Pure cocaine gained popularity in the late 19th century, but it was soon prohibited. Millions of people still use it illegally around the globe. Cocaine produces short-term euphoria and alertness by increasing the levels of dopamine, serotonin, and noradrenaline.
Long-term use causes addiction and an array of psychological disorders, sleep disturbances, cognitive impairments, and heart complications. Cocaine overdose can cause severe life-threatening damage to the heart and brain.
Cognitive-behavioral therapy can help cocaine addicts build healthier habits and improve their motivation, coping skills, and socialization.
