Signs of Cocaine Addiction: What to Look for and When to Get Help
What is cocaine use disorder?
Cocaine use disorder is the clinical diagnosis for problematic cocaine use — a DSM-5 diagnosis characterized by a pattern of use that causes significant impairment or distress across at least two criteria over a 12-month period. Mild disorder: 2-3 criteria. Moderate: 4-5. Severe: 6 or more. Casual or recreational cocaine use can become a disorder faster than most people expect, particularly in young adults whose brain reward systems are still developing.
If you’re reading this because you’re worried about someone you care about — or because you’re honest enough to wonder about yourself — the most useful thing is clinical specificity. Not a list of dramatic warning signs that only apply at the end stage, but a clear picture of what cocaine addiction actually looks like in a young adult who’s still functioning.
The DSM-5 Criteria for Cocaine Use Disorder
The American Psychiatric Association’s DSM-5 identifies 11 criteria for stimulant use disorder (which includes cocaine). Two or more in a 12-month period constitutes a diagnosis. The criteria are: taking more cocaine than intended; wanting to cut down but being unable to; spending significant time obtaining, using, or recovering from cocaine; craving cocaine; failing to meet obligations at work or school; continuing use despite relationship problems; giving up activities because of cocaine; using in situations where it’s physically hazardous; continuing use despite knowing it worsens a health problem; tolerance (needing more to achieve the same effect); withdrawal (characteristic crash when stopping).
The list is worth knowing because it shifts the question from ‘does he seem like an addict’ to ‘how many of these are true.’ Most families significantly underestimate the severity of what they’re watching because they’re measuring against a stereotype of end-stage addiction rather than against a clinical standard.
Behavioral Signs
Changes in routine: cocaine users often shift their schedule to accommodate use — later nights, erratic sleep, periods of high energy followed by crashes. Social withdrawal or conversely increased social activity in new, unknown circles. Financial problems that don’t have a clear explanation. Secretiveness about whereabouts, contacts, or finances. Declining performance at work or school that doesn’t match prior patterns.
Physical Signs
Nosebleeds, chronic runny nose, or sniffling unrelated to illness — these result from snorting cocaine, which damages nasal tissue over time. Dilated pupils, particularly in non-bright environments. Weight loss from appetite suppression. Bloodshot eyes. Periods of markedly elevated energy and confidence, followed by profound fatigue or irritability. Neglect of physical hygiene or appearance.
Psychological Signs
Paranoia — cocaine at high doses or with prolonged use produces paranoid thinking that can look like acute psychosis. Mood swings between euphoria and dysphoria. Increased anxiety. Irritability and short-temperedness, particularly when not using. Grandiosity or inflated sense of competence during use. Difficulty experiencing pleasure from ordinary activities (anhedonia) during abstinence, as the dopamine system adjusts.
The Fentanyl Contamination Risk
The cocaine supply has changed significantly in the past several years. CDC overdose data documents a marked increase in cocaine-involved overdose deaths — driven primarily by fentanyl contamination. Someone using cocaine today may be using a product that contains fentanyl without knowing it. People who use cocaine do not have opioid tolerance; a fentanyl-contaminated line that would be a sub-lethal dose for an opioid-tolerant person can be fatal for a cocaine user. This contamination risk is not theoretical — it is a leading cause of death among people who use cocaine and is one of the most important reasons to seek treatment now rather than later.
When Psychological Symptoms Include Suicidal Thinking
The crash period after cocaine use — particularly in someone with heavy, long-term use — can produce severe depression and, in some cases, suicidal ideation. This is a documented feature of cocaine withdrawal and should be treated as a mental health emergency, not a temporary mood that will pass.
If someone is expressing suicidal thoughts:
Call or text 988 (Suicide and Crisis Lifeline) — available 24 hours a day, seven days a week.
Go to the nearest emergency room or call 911 if there is immediate risk of harm.
What to Do When You Recognize the Signs
Having the conversation is the hardest part for most families. Accusations and ultimatums typically don’t work — and confronting someone in a state of cocaine-induced paranoia or mid-crash depression can make things worse. The most productive approach is direct, calm, and specific: naming what you’ve observed without dramatizing it, expressing concern without anger, and having the conversation when the person is neither high nor in the depths of a crash.
If the person isn’t ready for treatment, that doesn’t mean the conversation was wasted. Most people who enter treatment have had multiple prior conversations. SAMHSA’s National Helpline (1-800-662-4357) provides confidential guidance for families navigating this — available 24 hours a day, free of charge.

Frequently Asked Questions
What are the signs of cocaine addiction?
The DSM-5 identifies 11 criteria for stimulant use disorder including cocaine: taking more than intended, failed attempts to cut down, significant time spent on cocaine, cravings, failing obligations, relationship problems, giving up activities, hazardous use, use despite health problems, tolerance, and withdrawal. Two or more criteria over 12 months constitutes a diagnosis.
How can you tell if someone is using cocaine?
Behavioral signs include erratic sleep, financial problems, secretiveness, and social withdrawal. Physical signs include nosebleeds, dilated pupils, weight loss, and energy crashes. Psychological signs include paranoia, mood swings, and irritability. These signs together — especially the behavioral and financial patterns — are often the most visible to families.
Is fentanyl found in cocaine?
Yes. The current cocaine supply is increasingly contaminated with fentanyl. CDC overdose data documents a significant rise in cocaine-involved deaths driven by this contamination. People who use cocaine typically have no opioid tolerance, making fentanyl-contaminated cocaine particularly dangerous.
What should I do if I think a family member is addicted to cocaine?
Have a direct, calm conversation naming specific observed behaviors — not during active use or a crash. SAMHSA’s National Helpline (1-800-662-4357) provides free, confidential guidance for families. If the person is ready for treatment, Red Oak Recovery can walk you through the admissions process.
