Overview InformationCoca is a plant. The leaves of the coca plant are the source of cocaine, which is an illegal drug that is used nasally, injected, or smoked for mind-altering effects. Cocaine is also an FDA-approved Schedule II drug. This means cocaine can be prescribed by a healthcare provider, but the process is strictly regulated. The worry about cocaine is that it is unsafe and highly addictive.
People use coca leaves to relieve hunger and fatigue, to enhance physical performance, and for asthma, altitude sickness, and other conditions, but there is no good scientific evidence to support these uses. Using coca can also be unsafe.
How does it work?The cocaine found in coca can cause an increase in brain activity and have numbing (anesthetic) effects. Cocaine is highly addictive.
Uses & Effectiveness
Likely InEffective for
- Athletic performance. Coca increases heart rate, but doesn't seem to improve heart output or other bodily responses to physical exercise.
Insufficient Evidence for
- Cocaine use disorder. Early research suggests that chewing coca leaf might improve mental health in people addicted to cocaine.
- Altitude sickness.
- Stimulation of stomach function.
- Other conditions.
Side Effects & SafetyWhen taken by mouth:Coca leaf without the cocaine (decocainized) is LIKELY SAFE for most people when used in normal food amounts. The cocaine contained in the coca leaf is LIKELY SAFE for use on the eye or skin when prescribed and monitored by a medical professional.
The cocaine contained in coca leaves is LIKELY UNSAFE when taken by mouth for medicinal uses and UNSAFE when taken by mouth for recreational uses. Cocaine is illegal and can cause hyperactivity, restlessness, excitement, migraine headaches, seizures, strokes, heart attacks, aneurysms, high blood pressure, and liver and kidney failure. As little as 1/4 of a teaspoon of cocaine can be deadly. Cocaine is highly addictive.
When inhaled: The cocaine contained in coca leaves is UNSAFE when inhaled for recreational uses. Cocaine is illegal and can cause hyperactivity, restlessness, excitement, migraine headaches, seizures, strokes, heart attacks, aneurysms, high blood pressure, and liver and kidney failure. As little as 1/4 of a teaspoon of cocaine can be deadly. Cocaine is highly addictive.
Special Precautions & Warnings:Pregnancy and breast-feeding: It's UNSAFE to inhale coca or take it by mouth if you are pregnant. The cocaine in coca might cause a miscarriage or birth defects. Coca use is also associated with sudden infant death syndrome (SIDS).
It's also UNSAFE to inhale coca or take it by mouth if you are breast-feeding. The cocaine in coca is excreted into breast milk, and harmful effects can occur in infants breast-fed by mothers who were recently exposed to cocaine.
Asthma: The cocaine in coca can make asthma worse. Don't use it.
Heart disease: The cocaine in coca can make heart disease worse. Don't use it.
Diabetes: Coca or the cocaine found in coca might increase blood sugar levels in some people. Coca might affect blood sugar control in people with diabetes.
High blood pressure (hypertension): Coca or the cocaine found in coca might increase blood pressure in some people. People prone to high blood pressure should avoid using coca.
History of stroke or at risk for stroke: If you have a history of stroke or are at high risk for having a stroke, do not use coca. The cocaine in coca increases the chance of dying from a broken blood vessel in the brain.
A condition called plasma pseudocholinesterase deficiency (PPD): People with PPD are more likely than others to have seizures and/or die after using coca.
Do not take this combination
Alcohol interacts with COCA
Coca contains cocaine. Cocaine can affect your thinking. Alcohol can also affect your thinking. Do not take coca if you have been drinking alcohol.
Nifedipine interacts with COCA
Coca contains cocaine. Taking cocaine with nifedipine increases the risk of serious side effects such as seizure.
The appropriate dose of coca depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for coca. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
