Route, dose, contaminants, repeated use, dehydration, exertion, and other drugs affect risk.<\/p>\n<div class=\"ai-evidence-box\">\n<h3>Key distinctions<\/h3>\n<ul>\n<li>Do not ignore chest pressure, fainting, palpitations with weakness, or breathlessness<\/li>\n<li>disclose cocaine use honestly to emergency clinicians because it changes assessment.<\/li>\n<\/ul>\n<\/div>\n<h2>Signs and patterns clinicians assess<\/h2>\n<p>A clinician looks at the pattern over time, its severity, the person\u2019s baseline, and the consequences\u2014not at one isolated behaviour. Relevant features can include:<\/p>\n<ul>\n<li>strong craving, binges, or repeated use despite plans to stop<\/li>\n<li>sleep loss, reduced appetite, agitation, suspiciousness, or mood swings<\/li>\n<li>spending increasing time obtaining, using, or recovering from stimulants<\/li>\n<li>nasal, respiratory, injection-related, or oral health problems depending on route of use<\/li>\n<li>a crash marked by fatigue, low mood, disturbed sleep, and reduced pleasure after stopping<\/li>\n<\/ul>\n<p>These signs are not a self-diagnosis. Intoxication, withdrawal, prescribed use, pain, sleep disorders, and mental-health conditions can overlap, so assessment should establish what is happening and what is immediately unsafe.<\/p>\n<h2>Health and safety risks<\/h2>\n<p>Risk depends on the substance or medicine, route, dose, frequency, combinations, physical health, mental health, and environment. Important concerns include:<\/p>\n<ul>\n<li>chest pain, arrhythmia, heart attack, stroke, seizure, overheating, or severe hypertension<\/li>\n<li>panic, aggression, paranoia, stimulant-induced psychosis, and suicide risk during a crash<\/li>\n<li>unpredictable strength or contamination, including possible opioid contamination in some markets<\/li>\n<li>injury and impaired decision-making during prolonged wakefulness<\/li>\n<li>complications from combining cocaine with alcohol or other drugs<\/li>\n<\/ul>\n<h2>Assessment and treatment<\/h2>\n<p>Good care starts with consent, dignity, and a clear assessment of immediate risk. Treatment intensity should be matched to clinical need rather than to marketing labels or a fixed programme length.<\/p>\n<ul>\n<li>medical and mental-health assessment, including cardiovascular and suicide-risk screening<\/li>\n<li>supportive withdrawal care focused on sleep, hydration, nutrition, mood, and safety<\/li>\n<li>structured psychological treatment, with contingency management where available<\/li>\n<li>treatment of co-occurring anxiety, depression, trauma, ADHD, or psychosis<\/li>\n<li>relapse prevention that addresses triggers, access, social networks, and high-risk situations<\/li>\n<\/ul>\n<p>Recovery plans should state who is responsible for medication, crisis support, physical-health follow-up, family communication, and continuing care. A lapse should trigger prompt reassessment and additional support\u2014not abandonment or shame.<\/p>\n<section class=\"ai-urgent-help\">\n<h2>When to seek urgent help<\/h2>\n<p>Call emergency services for chest pain, collapse, seizure, severe headache, one-sided weakness, extreme agitation, hallucinations with unsafe behaviour, overheating, breathing difficulty, or suspected overdose. Do not assume a person can simply sleep it off.<\/p>\n<\/section>\n<h2>Questions to ask a treatment provider<\/h2>\n<ul>\n<li>Who performs the medical and psychiatric assessment, and what are their current qualifications and registrations?<\/li>\n<li>How is withdrawal, overdose, suicide risk, medication, and physical illness managed?<\/li>\n<li>Which treatments are offered for this specific condition, and what evidence supports them?<\/li>\n<li>What happens if symptoms worsen or hospital care is required?<\/li>\n<li>How are outcomes, complaints, safeguarding, discharge, and continuing care handled?<\/li>\n<\/ul>\n<h2>Frequently asked questions<\/h2>\n<details class=\"ai-faq\">\n<summary>Can this condition be treated?<\/summary>\n<p>Yes. Treatment should be matched to the substance or behaviour, severity, withdrawal and overdose risk, physical and mental health, previous response, goals, and available support. More than one episode of care may be needed.<\/p>\n<\/details>\n<details class=\"ai-faq\">\n<summary>Does withdrawal mean someone has an addiction?<\/summary>\n<p>Not necessarily. Withdrawal can indicate physical dependence, including during appropriate prescribed treatment. Addiction additionally involves impaired control, prioritisation, and continued use despite harm. A clinician can distinguish these patterns.<\/p>\n<\/details>\n<details class=\"ai-faq\">\n<summary>What is the safest first step?<\/summary>\n<p>Arrange a confidential assessment with a qualified addiction or medical service. Use emergency services immediately for overdose, seizure, breathing difficulty, severe confusion, dangerous psychosis, or immediate suicide risk.<\/p>\n<\/details>\n<nav class=\"ai-related-guides\" aria-label=\"Related clinical guides\">\n<h2>Related guides<\/h2>\n<ul>\n<li><a href=\"https:\/\/addictioninfo.org\/cocaine-addiction\/\">Cocaine Addiction: Signs, Risks and Treatment<\/a><\/li>\n<li><a href=\"https:\/\/addictioninfo.org\/cocaine-withdrawal\/\">Cocaine Withdrawal: Symptoms, Timeline and Support<\/a><\/li>\n<li><a href=\"https:\/\/addictioninfo.org\/cocaine-detox\/\">Cocaine Detox: What It Involves and What Comes Next<\/a><\/li>\n<\/ul>\n<\/nav>\n<section class=\"ai-sources\">\n<h2>Sources and clinical guidance<\/h2>\n<p class=\"ai-source-note\">Sources are selected for clinical authority and public accessibility.
