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 cocaine use disorder.


Cocaine stimulates the brain to release large amounts of the hormone dopamine, which, when amassed in sufficient quantities, results in the euphoria commonly reported by cocaine abusers. As a person continues to use cocaine, a tolerance is developed, and 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.

Furthermore, when a cocaine user stops using abruptly, they experience a crash or withdrawal. This results in an extremely strong craving for more cocaine, as well as fatigue (being tired), loss of pleasure in life, depression , anxiety , irritability, sleepiness, and sometimes paranoia. These symptoms often prompt the user to seek more cocaine to alleviate these symptoms of withdrawal.

Your doctor will ask about your symptoms and medical history, and perform a physical exam. He or she will ask you specific questions about your cocaine use, such as how long you have been using cocaine and how often you use it.


Talk with your doctor about the best treatment plan for you. Treatment programs may be in- or outpatient. They may require that you have already stopped all cocaine use, they may involve a detoxification program, or they may begin working with you even though you are still actively using cocaine.


There are currently no medications available to treat cocaine use disorder specifically, but topiramate, modafinil, and baclofen have shown some promise in treating cocaine use disorder. In addition, antidepressant drugs may benefit people who are 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. Such therapies include contingency management, in which people receive positive rewards for staying in treatment and remaining cocaine-free. Also, cognitive behavioral therapy helps people who are addicted to cocaine learn to abstain and remain abstinent from cocaine.

Rehabilitation Programs

In rehabilitation programs, people with cocaine use disorder stay in a controlled environment for 6-12 months, during which they may receive vocational rehabilitation and other support to prepare to move back into society.


The best way to prevent cocaine use disorder is to never use cocaine, since it is highly addictive.
