• Cocaine Use Disorder

    (Cocaine Abuse; Cocaine Dependence)

    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 is cocaine in a rock crystal form. It can be heated so its vapors can be smoked.
    Cocaine use disorder is treatable. But, it takes hard work. 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 needed to maintain the euphoria.
    Release of Dopamine in the Brain
    neurotransmitter
    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, a crash or withdrawal occurs. This results in an extremely strong craving for more cocaine. It also results in fatigue, loss of pleasure in life, depression , anxiety , irritability, and sometimes paranoia. These withdrawal symptoms often prompt the user to seek more cocaine.

    Diagnosis

    Your doctor will ask about your symptoms and medical history. A physical exam will be done. The doctor will ask specific questions about your cocaine use, including 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

    There are currently no medicines to specifically treat cocaine use disorder. Treatment with medicine focuses on the symptoms of euphoria and craving. 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 stopping cocaine use

    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.
