About Cocaine

Cocaine is a powerful and highly addictive substance. Cocaine hydrochloride remains a schedule II controlled substance, as it has some legal therapeutic application as a pain reliever and vasoconstrictor, useful in association with some medical procedures. In most other cases, cocaine is an illegal substance—one that is widely abused for its pleasurable stimulant effects.

Cocaine can be found in a number of forms, including white powder, paste, or solidified and rock-like (the latter commonly referred to as "crack cocaine"). Whatever the form, cocaine acts as a strong stimulant substance that can:

  • Provide a rapid-onset, rewarding high.
  • Speeds up various physiologic processes via its central nervous system effects.
  • Influence both short- and long-term mental health.

Cocaine Effects Quiz question 1

Short-Term Effects of Cocaine

Dependent on the method with which it is used – e.g., smoked, snorted or injected – cocaine can be quite rapidly acting. One of cocaine’s effects in the brain is to increase dopamine release. Dopamine is a neurotransmitter that plays a role in the brain registering positive feelings, and “rewarding” the behaviors that led to those feelings to begin with. This increase of dopamine is, in part, what leads to the subjective "high" of cocaine use.

The high experienced after cocaine use is accompanied by a number of desired effects, including:

  • Feelings of euphoria.
  • Increased energy.
  • Grandiosity; inflated self-esteem.
  • Elevated mood.

Some people use cocaine in a misguided attempt to enhance performance or meet some other end goal. Since it temporarily decreases the need for sleep, some people will abuse the substance to stay alert, to study or to accomplish a strenuous task. Since it suppresses the appetite, it is also sometimes used as a weight loss tool. The long-term outcomes for both of these scenarios are bleak—people may find themselves tragically ensnared by addiction for what started as a grab for fleeting gains.

In way similar to other drugs of abuse, cocaine use is associated with unwanted short-term effects. Cocaine use may also bring about:

  • Feelings of restlessness.
  • Irritability and anxiety.
  • Panic.
  • Paranoia.

The method by which cocaine is administered has an influence on the short-term effects of the drug:

  • Snorted cocaine can have relatively delayed effects on the body, but leads to a longer high.
  • Smoking or injecting cocaine has a more rapid effect—with onset in as few as 7 seconds, but with duration of only 5-10 minutes.

    • The highs of shorter duration tend to carry more intense symptoms that can increase desire and rate of use. This is why crack cocaine is seen to be so highly addictive even when compared to snorted cocaine.

Cocaine is sometimes abused in combination with a number of other substances—further compounding its risks to health. Combining cocaine and alcohol can be particularly dangerous.

Side Effects

Whether used for short durations or extended stretches of time, any cocaine use is associated with side effects. Cocaine use can lead to a heart attack, even in those that are young and otherwise healthy. Taking large amounts of cocaine is associated with erratic and possibly violent behavior.

Other side effects of cocaine use include:

  • Tremors.
  • Muscle twitches or tics.
  • Paranoia.
  • Vertigo.
  • Constricted blood vessels.

  • Dilated pupils.
  • Increased heart rate.
  • Increased blood pressure.
  • Increased body temperature.
  • Decreased sexual function.

Cocaine Overdose

In 2011, more than 4,500 people died from cocaine overdose. Even though males are more likely to die from taking too much of the substance, it can happen to someone of any gender.

Overdose from cocaine can result in:

  • Cardiac arrest.
  • Stroke.
  • Respiratory arrest.
  • Sudden death.

The risk of overdose is compounded when cocaine is used with another dangerous substance like alcohol or other drugs. The combination of cocaine and heroin is particularly deadly. Known as a speedball—this mixture creates a serious risk of overdose.

Lasting Health Effects of Cocaine

When short-term use crosses the line into long-term use, the risks increase for new and exaggerated negative results. These lasting health risks illustrate the drastic impact cocaine has on the abuser’s physical health.

The potential health consequences of long-term use include:

  • Chronic, extreme fatigue.
  • Unrelenting headaches.
  • Abdominal pain.
  • Nosebleeds.
  • Significant weight loss.
  • Bloodborne diseases such as HIV and hepatitis from unsafe injection use.

  • Heart arrhythmias and heart attack.
  • Cardiac arrest.
  • Widespread ischemic vascular disease.
  • Stroke.
  • Seizures.
  • Respiratory arrest.
  • Death.

The Influence of Method of Ingestion on Drug Effects

Not only does the method of ingesting cocaine alter the immediate side effects, it also leads to different long-term effects:

  • Snorting cocaine can lead to losing your sense of smell, irritation of the nasal septum, sniffling, nosebleeds, and hoarseness.
  • Injecting cocaine can lead to puncture marks, collapsed veins, localized and systemic infection and allergic reactions.

Cocaine use over a long time period can also lead to addiction, depression, isolation from family and friends, psychosis, paranoia, and severe respiratory infections.

Cocaine Dependence

“My friends and I would go to the mall after school; we said we were getting chicken fingers, but I'd meet the drug dealer and spend $50 on a gram, then a longtime housekeeper would pick us up. We didn't even have our licenses, but there we were, doing coke at each other's houses. The rest of my friends' moms went through their stuff, but my mother trusted me, so I hid everyone's stash in my closet. But because I had access to it, I started doing coke by myself. I'd get high in the school bathroom or at home before writing a paper.”

Christina Huffington

Using cocaine can rapidly lead to tolerance and addiction:

  • Tolerance means that you need increasingly larger amounts of cocaine to get the same feeling because your body is building up a resistance to its effects. With repeated use, the body becomes dependent on, or acclimated to the presence of cocaine to elicit any good feelings.
  • Addiction occurs when you feel the compulsion to keep using in the face of personal and professional troubles caused by the substance use.

According to a paper in Neuropsychopharmacology, 5-6% of people who have recently begun using cocaine will become long-term users. This varies with each person’s individual brain chemistry, but the presence of dopamine in the brain is a highly rewarding feeling that most people will work to replicate.

Risk for addiction increases when there is an untreated mental or physical health concern that cocaine abuse masks. Some will self-medicate with illicit substances—meaning that they address their current problem through use of cocaine. For example, someone with undiagnosed depression may be drawn to the appeal of cocaine’s effects.

Signs of Addiction

Drug addiction is often marked by:

  • Taking risks you would not ordinarily take, such as driving while high or stealing to have enough money for drugs.
  • Abandoning and neglecting life priorities.
  • Experiencing troubled relationships due to more emphasis on abusing cocaine.
  • Entanglements with the legal system.
  • Continuing to use cocaine despite significant negative consequences.

Cocaine Effects Quiz question 5


Cocaine Withdrawal and Addiction Treatment


When a cocaine user becomes dependent on the drug, one’s body will have a strong, negative reaction to periods without cocaine. The most common effect of cocaine withdrawal is a "crash." A crash usually includes symptoms like:

  • Fatigue.
  • Feelings of depressions.
  • Restlessness.
  • Anxiety.
  • Increased hunger.
  • Increased paranoia and mistrust of others.
  • High desire to continue or restart using the substance.

The crash can last from hours to days depending on the frequency, amount, and period of previous use.

The cravings that accompany cocaine withdrawal can be intense, but can be treated with proper care and support. Treatment can take place on an inpatient, residential, or outpatient basis.

Inpatient care means that the cocaine addict is in a supervised, residential setting. Often, these settings will be staffed with medical and mental health professionals. Short-term detoxification may be needed to allow removal of the substance from the body in a safe, monitored environment to decrease withdrawal symptoms.

Residential treatment centers usually have a more home-like atmosphere. Those recovering from cocaine addiction live at the rehab center fulltime and focus exclusively on their recovery. Residential treatment may include individual or group counseling, medical treatment, or other types of therapy.

Outpatient treatment means that the cocaine addict lives at home and continues his or her daily routines while attending treatment on a regular basis. Again, this treatment will include a range of options including individual and group therapy sessions with a focus on mental health and drug and alcohol issues. By diagnosing and treating any underlying medical conditions, such as depression and attention-deficit disorder, there is a better rate of abstinence from cocaine and a higher likelihood of successful and long-term recovery.
