Crack is a solid form of cocaine, usually smoked. It contains the same active drug as powder cocaine, but smoking delivers it rapidly and the high is typically brief.12

What is the difference between crack and powder cocaine?
Crack is cocaine base. Powder cocaine is usually cocaine hydrochloride, the salt form. The usual route of use helps explain the biggest practical differences. Both can cause addiction, heart attack, stroke, seizures, and overdose.125
| Feature | Crack cocaine | Powder cocaine |
|---|---|---|
| Form | Small, irregular rocks | Usually a white crystalline powder |
| Common route | Smoked | Snorted |
| Typical high by that route | Starts rapidly and often lasts about 5 to 10 minutes | Starts within a few minutes and often lasts about 15 to 30 minutes |
| Route related risks | Airway irritation, wheezing, acute lung injury | Nosebleeds and damage inside the nose |
For nasal damage and the risks of combining cocaine with alcohol, see the powder cocaine guide.15
Is crack more addictive than powder cocaine?
Smoking gets cocaine to the brain quickly. A rapid, short high can reinforce repeated use in the same session. That helps explain why smoking can be particularly reinforcing compared with snorting. Addiction risk also depends on the pattern of use and individual circumstances.156
What does smoking crack do to your lungs?
Smoking crack can cause cough, wheezing, or shortness of breath and can worsen asthma. “Crack lung” describes an acute lung injury after smoking crack. It can involve shortness of breath, fever, low oxygen, or coughing up blood. Several other problems can cause similar symptoms, so tell emergency responders what was used and when if you know.47
Crack cocaine effects and signs of use
Short-term effects can include a rush of energy, increased alertness, a racing heart, sweating, and anxiety. Some people become agitated or paranoid. Repeated use can disrupt sleep and appetite and strain the heart. Coughing or wheezing after smoking can reflect airway irritation. These symptoms alone cannot identify the substance or establish addiction.124
Signs of crack cocaine addiction can include returning to smoking sooner than you planned, repeatedly trying to cut back, or continuing despite harm to your health or relationships. Clinicians assess the pattern as cocaine use disorder, a type of stimulant use disorder. If you’re worried about someone, describe what you’ve noticed and offer to help arrange a conversation with a clinician. See help for families.56
Crack withdrawal symptoms and how long they last
The crash after smoking can feel like exhaustion, irritability, or low mood. After repeated use, cutting back or stopping can bring cravings, more appetite, vivid dreams, and sleep changes. Sleepiness and irritability are common early on. Mood and sleep symptoms can persist for weeks or longer. The brief high and the withdrawal timeline are separate.68
Seek prompt help for severe depression or worsening symptoms. Call 911 if someone is in immediate danger. Tell the clinician about alcohol, benzodiazepines, opioids, or other substances. They can change the risks and what support you need.6
Crack cocaine addiction treatment
An assessment can help you decide what support you need to stop smoking crack. Tell the clinician about your most recent use, breathing problems, mood changes, and what happens between episodes. A clinician can help determine whether outpatient visits, a more intensive program, or medical monitoring are appropriate.6
What to ask a crack rehab program?
- Do you offer contingency management for stimulant use disorder? It uses tangible rewards for agreed treatment goals and has the strongest evidence for this condition.6
- Can you help me plan for the times and situations when I’m most likely to smoke again? Cognitive behavioral therapy and community reinforcement can be part of that plan.6
- Can you coordinate care for breathing problems, depression, or other substance use, and help me plan for the time between appointments?
There’s no FDA-approved medication specifically for cocaine use disorder. A clinician may consider off-label options for some people and treat co-occurring conditions. Peer support can also be part of recovery.68
Start with our treatment finder or a licensed clinician. Ask programs directly whether they treat stimulant use disorder and what services, costs, and insurance coverage you can expect.
