Cocaine and Crack Abuse

Cocaine is typically snorted or injected into a vein. It can also be rubbed onto the gums. Crack is made from cocaine. It can be smoked for a stronger effect. Cocaine causes a very powerful mental and physical dependence. 

Once you have a dependence, you'll do just about anything to get the drug and have the feeling it gives you. This can increase your risk for:

  • Overdose that may lead to death

  • Loss of your job, your home, or your family

  • Accidental injuries to yourself or others while you are under the influence of the drug (in a car or at home)

  • Arrest, conviction, and jail sentence for possession of an illegal substance or for driving under the influence

Medically, cocaine can affect every organ in your body. It can cause:

  • Chest pain, heart rhythm problem (arrhythmia), heart attack, and heart failure

  • Very high blood pressure

  • Severe headache, seizures, loss of consciousness, and stroke

  • Anxiety, psychosis, confusion, paranoia, and hallucinations

  • Nasal damage from snorting

  • Nausea, belly (abdominal) pain, and loss of appetite

  • Chronic bronchitis and shortness of breath from smoking

  • Higher risk for HIV infection, hepatitis B or C, and heart infection. This is from IV use, risky sexual behavior while high, or both. 

  • Kidney failure

Home care

These tips will help you care for yourself at home:

  • Admit you have a drug problem. Ask for help from your family and close friends.

  • See a mental health provider or counselor if you have depression or anxiety.

  • Join a self-help group for drug abuse.

  • Stay away from people who abuse drugs themselves or who tempt you to continue abusing the drug.

  • Eat a balanced diet and start a regular exercise program.

If you continue to use IV cocaine, lower your risk of getting or spreading infection by:

  • Using only sterile equipment

  • Not reusing or sharing equipment

  • Cleaning your skin before injecting

Call 911

  • Seizure

  • Hard time breathing or slow, irregular breathing
