How to Identify the Signs of Cocaine Use

Cocaine is a highly addictive drug that is prevalent worldwide. Experts estimate that nearly 25 million people in the United States alone have experimented with cocaine at least once in their lifetime. Cocaine is often snorted through the nose, but it can also be smoked or injected, with each method carrying its own set of risks and negative effects. By learning about the signs and symptoms of cocaine use, you can identify if someone close to you may be using cocaine and decide on the appropriate intervention method.

Watch for dilated pupils. The pupils of a cocaine user’s eyes will enlarge due to the stimulating effects of the drug.

• Observe for enlarged pupils (the dark circle in the eyes) even in well-lit rooms.
• Pupil dilation may also be accompanied by red eyes or visible blood vessels, though this is not always the case.

Look for unusual signs around the nose. Many people use cocaine by snorting it, so one of the key signs of cocaine use is problems with the nose. Keep an eye out for the following symptoms:

• Runny nose
• Nosebleeds
• Damage inside the nose
• Difficulty swallowing
• Decreased sense of smell
• Residue of white powder around the nostrils

Watch for a rapid heart rate. Cocaine is a stimulant, so one of the physical symptoms of cocaine use is an increased heart rate. In some cases, this can lead to arrhythmia (irregular heartbeat), rapid breathing, and even sudden death due to heart failure.

• Normal heart rate for adults is 60-100 beats per minute.
• Note that heart rate can be influenced by factors unrelated to drug use, including physical activity, environmental temperature, body posture, emotional state, and even legal medications. Therefore, you cannot solely rely on heart rate as a definitive sign of stimulant use.

Recognize signs of using crack cocaine. Another method of using cocaine is smoking it. Crack cocaine, often in the form of hard “rocks,” is made by mixing powdered cocaine with water and baking soda.

• Signs of crack cocaine use include burn marks on the fingers or lips caused by lighters and smoking the drug using a special pipe, commonly called a crack pipe.

Look for signs of drug injection. Some people use needles to inject cocaine into their veins. This method provides immediate effects but carries many risks, including endocarditis (inflammation of the heart lining), heart conditions, abscesses/infections, and an increased risk of overdose. Injection drug use also heightens the risk of blood-borne diseases such as hepatitis and HIV.

• Signs of drug injection include needle marks, often seen on the arms, skin infections, or allergic reactions caused by additives mixed with the cocaine.

Recognize cocaine use through oral consumption. Taking cocaine orally is another method of use. Unlike smoking, snorting, or injecting, oral ingestion of cocaine does not show many outward signs. However, it can cause serious damage to the intestines and stomach due to decreased blood flow and the digestive system’s sensitivity to stimulants. When cocaine is consumed orally, the most noticeable signs are typical stimulant symptoms, such as:

• Agitation
• Excessive excitement
• Hyperactivity
• Loss of appetite
• Delirium
• Hallucinations

Pay attention to their speech patterns. Cocaine and other stimulants typically cause overly excited behavior. Common signs in the speech of a cocaine user include:

• Excessive talking
• Speaking rapidly
• Constantly switching topics

Notice reckless behavior. Cocaine can create a feeling of invincibility in frequent users, leading to risky behaviors such as unsafe sexual activity, violent tendencies like fighting, domestic abuse, suicidal thoughts, and even murder.

• Unsafe sexual activity can lead to pregnancy, illness, and/or sexually transmitted diseases.
• High-risk behaviors can result in legal issues, severe injury, or even death.

Recognize behavioral changes. Cocaine users often devote considerable time and energy to their drug use. Signs of such behavior include:

• Avoiding responsibilities or obligations
• Frequently disappearing, going to the bathroom, or leaving the room only to return with an unusual mood

Be aware of dramatic mood swings. Cocaine is a stimulant that can cause sudden and sharp mood shifts. This can manifest as restlessness, sudden bursts of excitement, reckless behavior, or a drastic change between extreme moods.

Watch for signs of social withdrawal. A common behavior among drug users is the tendency to pull away from social interactions, either by isolating themselves or surrounding themselves only with other drug users.

• Although withdrawal from social circles can also be caused by factors like anxiety or depression, it can also indicate drug use.

Look for signs of a loss of pleasure. Many drug addicts lose interest in activities or hobbies they once enjoyed, but this is especially noticeable in cocaine users. The reason is that cocaine damages the brain's circuits responsible for generating pleasure.

• Watch for signs of depression and a lack of joy in daily activities, a common symptom of prolonged cocaine use.

Search for straws and hollow tubes. Depending on the method of consumption, various items can be linked to cocaine use. Snorting is the most common method, so associated items may include:

• Pen casings
• Straws
• Rolled-up bills or those that appear to have been rolled
• Razor blades, credit cards, or ID cards with white powder residue along the edges

Watch for crack cocaine paraphernalia. Cocaine users often use pipes, which can be made from glass or rolled-up aluminum foil. Look for items such as:

• Small glass pipes
• Aluminum foil
• Lighters
• Empty plastic bags, including those used to store small chunks of crack cocaine

Look for signs of drug injection. Although less common than smoking or snorting, injecting drugs is still a widespread method of use. Look out for the following items:

• Syringes
• Tourniquets, including belts or shoelaces
• Spoons that may have burn marks on the bottom
• Lighters
