Recognizing the signs of cocaine use isn’t always easy, especially if the person is trying to hide it. But early detection is critical. Whether it’s a loved one, friend, or coworker, knowing what to look for, and how to respond, can make all the difference.

In this guide, we’ll explore the physical, behavioral, and psychological symptoms of cocaine use, how to intervene with care, and what treatment options are available to support long-term recovery.

Physical Signs of Cocaine Use

Cocaine affects the body quickly and dramatically. Some of the most noticeable physical indicators may include:

Short-Term and Visible Indicators

1. Dilated pupils and bloodshot eyes
2. Runny nose or frequent nosebleeds (especially without illness)
3. Burned lips or fingers, typically from smoking cocaine
4. White powder residue around the nostrils or on belongings
5. Significant weight loss and loss of appetite

You may also notice increased restlessness or fidgeting as the stimulant effects of the drug take hold. The National Institute on Drug Abuse (NIDA) offers additional resources on drug-related physical effects.

Common Cocaine Paraphernalia

Keep an eye out for items such as:

1. Rolled-up dollar bills or straws
2. Razor blades and small mirrors
3. Small baggies, capsules, or vials
4. Hollowed-out pens or syringes (for users who inject)

These items may be hidden in plain sight or disguised among everyday belongings.

Behavioral and Emotional Changes

Cocaine impacts more than just the body. It often alters mood, judgment, and overall behavior.

Mood and Personality Shifts

1. Sudden bursts of high energy or talkativeness
2. Overconfidence or risky behavior
3. Anxiety, paranoia, or aggressive mood swings
4. Irritability or volatility
5. Withdrawal from friends, family, or responsibilities

In many cases, someone using cocaine may seem “up” one moment and agitated or emotionally distant the next. These behavioral changes are among the most telling signs of substance use. Healthline offers a detailed breakdown of stimulant-related behavioral symptoms.

Mental and Psychological Effects

Cocaine also has a direct effect on brain function, often worsening existing mental health symptoms or triggering new ones.

Common Psychological Symptoms

1. Restlessness and insomnia
2. Paranoia or delusional thinking
3. Depression, especially after a binge or “crash”
4. Hallucinations (in cases of prolonged or high-dose use)
5. Fatigue and apathy during withdrawal phases

Over time, the highs become less intense, and the psychological crashes become more severe. This cycle can significantly disrupt a person’s ability to think clearly or make safe decisions.

Long-Term Health Risks and Consequences

Continued cocaine use can cause serious long-term health issues, some of which can be irreversible.

Serious Health Complications

1. Chronic nosebleeds or “coke nose” (damaged nasal tissue)
2. Heart attacks, strokes, and seizures
3. Loss of smell and breathing problems
4. Ongoing mental health decline, including suicidal ideation
5. Legal, financial, or employment troubles due to erratic behavior

For families and caregivers, these consequences can be heartbreaking to witness. The SAMHSA National Helpline is available 24/7 to provide information and support for those facing substance use concerns.

Recognizing Cocaine Addiction and Dependence

Occasional use can quickly escalate into dependency. Here’s how to tell when cocaine use may have become an addiction:

Signs of Cocaine Addiction

1. Increased tolerance, requiring more of the drug for the same effect
2. Intense cravings when not using
3. Withdrawal symptoms like fatigue, depression, or irritability
4. Neglecting responsibilities like work, school, or family
5. Hiding use or reacting defensively when asked about it

Addiction is a medical condition, not a character flaw. Understanding this distinction is key to approaching the situation with empathy rather than judgment.

How to Help Someone You Suspect Is Using Cocaine

If you’re concerned about someone’s behavior, the way you approach them matters. Avoid blame or panic, and instead aim for a supportive, fact-based conversation.

Compassionate Conversation Tips

1. Choose a quiet time to talk, without distractions
2. Express your concern using specific observations
3. Use “I” statements, like “I’ve noticed you’ve been really anxious lately”
4. Stay calm, even if they deny or downplay their use
5. Avoid issuing ultimatums or threats

Sometimes, even the most heartfelt conversations aren’t enough to spark change. That’s when it may be time to seek outside help.

When to Seek Professional Support

1. Contact an addiction specialist or licensed therapist
2. Consider organizing a structured intervention
3. Encourage a mental health evaluation, especially if symptoms include paranoia or suicidal thoughts
