Cocaine use can harm many different areas of your body. One of the parts of the body that cocaine can damage is your brain. Cocaine can hurt your brain by interfering with the way you understand the world around you. Doctors have known for a long time that cocaine can cause changes in a person’s mental status. One of those changes is psychosis, which involves losing touch with reality.

What Does Cocaine Do to the Brain to Cause Psychosis?
Cocaine is addictive because it triggers the brain’s reward system. This system causes a release of the brain chemical dopamine. Doctors believe that when too much dopamine releases, psychosis can be a result. Doctors also learned about a brain chemical called brain-derived neurotrophic factor (BDNF). Studies have shown that levels of this chemical can be abnormally low in people with different kinds of psychosis, including cocaine psychosis. Doctors are still learning more about BDNF and what it means for the brain.
Psychosis Symptoms & Risk Factors
Being paranoid is often one of the first symptoms of cocaine psychosis. Some doctors think that the more cocaine you use, the more you will be at risk of certain psychotic symptoms. For example, more cocaine use may put you more at risk for feeling objects (often described as bugs crawling) on your skin that are not there.
Other symptoms of psychosis include:
- Having false beliefs
- Being paranoid
- Seeing, hearing or feeling things that are not there
- Speech that does not make sense
- Inappropriate behavior
- How old you were when you first started using cocaine: People who started using cocaine before the age of 20 may be at a higher risk of psychosis.
- How much cocaine you use: Higher doses of cocaine may be more likely to cause psychosis.
- If you smoke or inject cocaine: Smoking or injecting cocaine have a high risk of causing psychosis.
- If you use other substances along with cocaine: Using alcohol or other drugs, especially other drugs that may cause mental status changes, may increase the risk of experiencing psychosis.
- If you already have any mental health problems: Preexisting mental health issues may put you at higher risk of psychosis.
- How much you weigh: The thinner you are, the more you may be at risk of developing cocaine psychosis.
How Common is Psychosis from Cocaine Use?
Cocaine psychosis is very common. Doctors have found that up to 86% of people who use cocaine may experience psychotic symptoms at some point. About 96% of people with cocaine psychosis will have hallucinations. Hearing the non-existent is the most common kind of hallucination experienced with cocaine. Additionally, along with that 96%, about 90% of people with cocaine psychosis experience symptoms of paranoia.
How Do You Treat Cocaine Psychosis?
Treatment of cocaine psychosis depends on the symptoms. Sometimes the symptoms may go away on their own without treatment. However, in severe cases, specialized care may be needed, like admission to a psychiatric hospital. You should seek medical attention if the person with cocaine psychosis seems to be a danger to themselves or others. Doctors may treat cocaine psychosis with medications like:
Cocaine psychosis may go away on its own 24 to 48 hours after the last dose of cocaine. However, in some cases, it may take a few weeks for symptoms to go away completely. It is also important to note that someone who has had cocaine psychosis is at higher risk for more episodes of psychosis. These future psychotic episodes can happen even if the person is using less cocaine than they did previously.
