Cocaine is often cut with other substances such as baking soda, caffeine, lidocaine, or even dangerous drugs like fentanyl. These additives can increase profits for dealers, change the effects of the drug, and significantly raise the risk of serious health complications or overdose.
Understanding What Cocaine Is
Cocaine is a highly addictive stimulant drug (National Institute on Drug Abuse, 2024). Users take it for its mood-enhancing and euphoric effects. A person can become addicted to cocaine after only one use because it is so addictive. Signs of cocaine addiction include cravings, weight loss, paranoia, lying or stealing money to get more cocaine, and failing to uphold responsibilities.
Cocaine affects dopamine, a natural chemical your brain makes, and essentially hijacks your body’s reward center. A person with a substance use disorder sees cocaine as a reward, which makes the brain want more.
It has become more common for dealers and manufacturers to “cut” the drug with chemical agents due to several reasons. For one, cocaine is a very expensive drug, and by adding in another substance, they can make it look like the user is getting more than they really are. Another reason they do this is to intensify the high so the user becomes hooked more quickly, driving them to purchase more in a shorter timeframe.
What Do People Cut Cocaine With?
Cocaine is commonly cut with a range of substances that either increase volume or enhance effects. Some additives are relatively inexpensive fillers, while others are active drugs that can increase danger. Common cutting agents include:
- Baking soda
- Laxatives
- Laundry detergent
- Boric acid
- Levamisole (a deworming medication)
- Caffeine or amphetamines
- Lidocaine or benzocaine (numbing agents)
- Fentanyl (increasingly common and highly dangerous)
Because there is no regulation of illegal drugs, users often have no way of knowing what substances are present. This unpredictability significantly increases the risk of overdose, infection, and long-term health complications.
Where Cocaine Comes From
Cocaine is made from leaves harvested from the coca plant, which is indigenous to South America (Biondich and Joslin, 2016). It has several alkaloid compounds and has been a staple of Andean life for thousands of years. Miners and others who work in the Andes chew on the leaves to help them cope with the altitude.
One of the alkaloids found in the coca leaf is cocaine, which is a stimulant. Cocaine is extracted and sold in many forms. The most common forms are a white powder as well as a crystalline form that is referred to as “crack” cocaine. Users of these substances consume them by snorting, smoking, or injecting the drug into their bodies.
The Effects of Cocaine Consumption
Cocaine creates a feeling of euphoria in users and also energizes them. In the Andes, a typical user of coca leaves might consume about 4 milligrams of alkaloids a week. However, a typical user of cocaine can consume up to 50mg in a session, and those using crack can consume even more. This can lead to blood concentrations that are 50 times greater for users of powder forms of cocaine than for those who chew the leaves.
People using cocaine or crack will experience a brief period of euphoria. During this “high,” they will feel exhilarated and energized. They may be more talkative and mentally alert. They might discover it’s easier for them to perform both mental and physical tasks, and they may find that cocaine use decreases their need for food and sleep. Some users also report feeling more sensitive to sensory inputs such as light or sound.
What Happens After the High Wears Off?
Unfortunately, this “high” seldom lasts for more than an hour, and when it’s over, users experience a deep “low.” Users find themselves craving the “high” again and will often seek more cocaine. For this reason, cocaine is extremely addictive and is classified as a Schedule II narcotic by the US Drug Enforcement Administration (DEA, n.d.).
In addition to the perceived effects of the drug on users, there are also physiological effects such as dilated pupils and increased blood pressure. As users seek ever larger doses of the drug, they may start to exhibit erratic and even violent behavior. Many users of cocaine report feeling paranoid, restless, irritable, or anxious. There may also be physical ramifications, such as vertigo and tremors.
Tampering With or “Cutting” Cocaine
Dealers often “cut” cocaine and crack with other substances, adding to the potential for adverse side effects. These impurities can often create health hazards separate from any that are intrinsic to cocaine itself.
Because cocaine and crack are illicit drugs, there is no government oversight ensuring the purity of the product. Consumers take a risk every time they buy these drugs for recreational use. They can only hope that the vendor is selling them a pure product as advertised.
Common Reasons Cocaine Is Cut
One obvious reason for cutting cocaine is that by substituting some volume of the drug with cheaper substances, dealers can increase their profits. Therefore, those who sell drugs have a vested interest in tampering with the product.
Another reason to cut cocaine seems counterintuitive. Some dealers will add substances that actually increase the high that the user will experience. However, they typically only do this for new customers to get them more firmly hooked on the product.
Another less egregious motivation for cutting cocaine is to actually make the powder flow better, making it easier to use. Some cutting agents will change the texture of the drug, for example, making it easier to inhale. Since cocaine will often pass through many hands before getting to the end-user, many types of substances may be added to the product that is ultimately consumed.
Common Additives Used to Cut Cocaine
Substances Used to Increase Volume
- Laundry detergent
- Baking soda
- Laxatives
- Meat tenderizer
- Boric acid
- Levamisole (a cattle dewormer)
- Talcum powder
Substances Used to Intensify Effects
- Caffeine
- Amphetamine
- Creatine
- Aspirin
- Benzocaine and Lidocaine (pain relief medications)
- Procaine (a local anesthetic)
The addition of numbing agents to cocaine helps numb the nasal passages for users, thus giving them a feeling of less irritation.
One alarming trend is the increasing presence of fentanyl in cocaine, which dramatically raises the risk of overdose and death, even in small amounts (National Institute on Drug Abuse, 2025).
Levamisole is another dangerous substance added to cocaine. It is normally used to deworm cattle. While doctors formerly used it to treat people for parasites, it was discontinued as it severely depletes white blood cells. By 2011, it was discovered that almost three-quarters of all cocaine tested by the DEA contained levamisole.
Other Forms of Cocaine
Dealers not only cut cocaine to better “hook” customers or to make more money from a certain volume of product, but they also alter its form in other ways. For example, some dealers may sell “freebase cocaine.” Freebasing increases the potency of cocaine by altering its structure (Santos-Longhurst, 2020). Users cannot heat or smoke cocaine in its normal form. However, once it is free-based, users can smoke it, allowing a more potent delivery system.

Why is cocaine cut with other substances?
Dealers cut cocaine to increase profits, enhance effects, or change the texture of the drug. This practice makes the drug more dangerous and unpredictable.
What is the most dangerous substance found in cocaine?
Fentanyl is one of the most dangerous substances found in cocaine today. It is extremely potent and has been linked to a growing number of overdose deaths.
Can you tell what cocaine is cut with?
No, it is often impossible to tell what cocaine is cut with by appearance alone. Many additives look similar to cocaine, making testing the only reliable method.
