Definition

Cocaine use disorder is when the use of cocaine harms a person’s health or social functioning, or when a person becomes dependent on cocaine. The powdered form of cocaine can be snorted or dissolved in water and injected. “Crack,” which is cocaine in a rock crystal form, can be heated and its vapors smoked.

Cocaine use disorder is treatable. But, it takes perseverance and determination. Talk to your doctor if you think you have this condition.

Causes

Cocaine stimulates the brain to release large amounts of the hormone dopamine. Dopamine results in the euphoria commonly reported by cocaine abusers. As a person continues to use cocaine, a tolerance is developed. This means that higher doses and more frequent use are required to maintain the euphoria.

Release of Dopamine in the Brain

The dopamine connecting to the receptors causes a euphoric feeling. This occurs naturally, but cocaine causes an exaggerated response that can lead to addiction.

When a cocaine user stops using abruptly, he experiences a crash or withdrawal. This results in an extremely strong craving for more cocaine. It also results in fatigue (being tired), loss of pleasure in life, depression, anxiety, irritability, and sometimes paranoia. These withdrawal symptoms often prompt the user to seek more cocaine.

The following factors increase your chances of developing cocaine use disorder. If you have any of these risk factors, tell your doctor:

Diagnosis

Your doctor will ask about your symptoms and medical history. He will also do a physical exam. The doctor will ask specific questions about your cocaine use, like how long you have been using the drug and how often.

Treatment

Talk with your doctor about the best treatment plan for you. Treatment programs may be inpatient or outpatient and may:

  • Require that you have already stopped using cocaine
  • Involve a detoxification program

Medications

Treatment with medicine centers on the symptoms of euphoria and craving. But, there are currently no medicines to specifically treat cocaine use disorder. Medicines that have shown some promise include:

  • Modafinil
  • N-acetylcysteine
  • Topiramate
  • Disulfiram
  • Agonist replacement therapy
  • Baclofen
  • Antidepressants—may be helpful for people in the early stages of cocaine abstinence

Behavioral Therapy

Behavioral therapies to help people quit using cocaine are often the only available, effective treatment for cocaine use disorder. Therapies include contingency management. With this program, people receive positive rewards for staying in treatment and remaining cocaine-free. Also, cognitive behavioral therapy helps people to learn how to abstain and remain abstinent from cocaine.

Rehabilitation Programs

In rehab programs, people with cocaine use disorder stay in a controlled environment for 6-12 months. During this time, they may receive vocational rehab and other support to prepare them to return to society.

Prevention

The best way to prevent cocaine use disorder is to never use cocaine. It is highly addictive.
