In this article, we take a closer look at cocaine, what it is, how it is used, the side effects of cocaine use and more.

What is cocaine?

Cocaine is a stimulant drug produced from the leaves of the coca plant (Erythroxylum coca), a plant that grows across Central and South America. However, it can also be manufactured synthetically.

Cocaine is available in two forms: cocaine hydrochloride (a white powder) and cocaine base (cream-colored rocks).

When a person uses cocaine, it is converted by the body into the metabolites benzoylecgonine and norcocaine.

What are the street names for cocaine?

Some of the most common street names for cocaine include:

  • Coke
  • Coca
  • Crack
  • Crank
  • Rock
  • Snow
  • Soda
  • Flake

What does cocaine look like?

Cocaine is available in several forms including a powder, which is often white/off-white in color, a white or light brown paste, or white/off-white crystals. These crystals are known as crack cocaine.

How is cocaine used?

Recreational drug users typically snort, smoke, or inject cocaine. It is also rubbed into the gums.

How do people behave when they take cocaine?

After using cocaine, a person may experience a ‘cocaine high’ leading to increased confidence, agitation, and/or feelings of intense pleasure, power, and increased energy.

However, it can also make a person more prone to violence, anxiety, panic attacks, aggression and risk-taking.

What are the side effects of cocaine?

The physical side effects of cocaine can vary and depend on several factors, including how the drug is ingested, frequency of use, and the metabolism and weight of the person.

Some common side effects include:

  • Headaches
  • Seizures
  • Stomach cramps
  • Paranoia
  • Raised body temperature
  • Erosion of the nasal cavity over time (if snorted)

More serious risks of taking cocaine include heart attacks and strokes.

What happens when you use cocaine with other drugs?

Below is an overview of the side effects of using cocaine alongside other drugs.


Consuming alcohol alongside cocaine can be extremely risky, leading to increased heart rate and high blood pressure. This can increase a person’s risk of a heart attack.

When a person consumes alcohol and cocaine together, this causes cocaethylene to be formed in the body: a metabolite that is only present when cocaine has been used alongside ethanol (the intoxicating agent in alcoholic drinks).


Heroin and cocaine have opposing effects on the central nervous system, with heroin being a depressant and cocaine being a stimulant.

When the two are used together, this can cause breathing difficulties, as well as putting strain on the heart.

MDMA (Ecstasy)

Both MDMA (ecstasy) and cocaine are stimulant drugs. When used together, this can lead to over-stimulation and increased heart rate, which can prove fatal.

What is the legal status of cocaine in the US?

Because of its high potential for abuse, cocaine> is classed as a Schedule II substance under the Controlled Substances Act.

Can cocaine be used in medicine?

Although rarely used in medical settings, cocaine hydrochloride solution (4% and 10%) can be used as a topical local anesthetic.

When applied to certain areas of the body such as the nose, mouth, or throat, it can cause loss of feeling or numbness, allowing minor procedures to be performed without causing pain.

It can also be used prior to surgery involving the nose, mouth and throat, helping to narrow the blood vessels and reduce bleeding.

How long does it take for cocaine to show up in a drug test?

Even after the ‘high’ has worn off, and long after the drug was first consumed, cocaine use can be detected by a drug test, depending on the type of test you take.

The drug testing detection windows for cocaine are as follows:

  • Oral fluid (saliva) – up to 48 hours
  • Urine – up to 4 days
  • Hair – up to 12 months (depending on the length of hair available)
  • Nails – up to 12 months (up to 6 months for fingernails and up to 12 months for toenails)

Oral fluid and urine drug testing are known as ‘narrow-window’ forms of testing and can be used to detect drug use from 30 minutes after consumption, up to a few days.

This can vary depending on the type of substance and how much was used.

The rate at which hair and nails grow means that both hair drug testing and nail drug testing can provide a ‘wide-window’ of detection for drugs and their metabolites (up to 12 months).
