Learn about drug induced psychosis, including its symptoms, causes, and treatment options in this informative article.

What Is Drug-Induced Psychosis?

Often, psychosis occurs as the result of a mental disorder; however, it can also develop through substance use. Drug-induced psychosis, also known as stimulant psychosis, is characterized as experiencing a psychotic episode (e.g., delusions, hallucinations, paranoia) triggered by substance abuse and misuse.

Drug-Induced Psychosis vs. Schizophrenia

While these two conditions share similarities, there are a few differences between drug-induced psychosis and schizophrenia.


Schizophrenia is a mental health disorder that causes an altered sense of reality, affecting how people think, feel, and behave due to periods of psychosis. While there is no singular established cause of schizophrenia, research shows that substance abuse can trigger schizophrenia symptoms. For example, one study found that 11% of participants with substance-induced psychotic disorder developed schizophrenia.1

Drug-Induced Psychosis

Drug-induced psychosis is a psychotic episode that occurs from substance abuse. While it can develop during active drug use, it’s more common during withdrawal. In addition, unlike schizophrenia, which is a lifelong disorder, drug-induced psychosis is temporary, lasting no more than a few days.

How Common Is Drug Induced Psychosis?

Because the statistics surrounding drug-induced psychosis vary based on the substance, it can be difficult to understand exactly how common it is. Nonetheless, a study has provided perspective on the prevalence of drug-induced psychosis for amphetamines, cannabis, cocaine, and opiates in individuals ranging from no substance use disorder to severe substance use disorder.

Different Drugs That Can Trigger Drug Induced Psychosis

The findings of this study will be detailed below:2


  • Amphetamines: 5.2% to 100%
  • Cannabis: 12.4% to 80.0%
  • Cocaine: 6.7% to 80.7%
  • Opiates: 6.7% to 58.2%

How Long Does Drug-Induced Psychosis Last?

The drug-induced psychosis timeline can vary based on many factors, including the substance, severity of abuse, and duration of abuse. However, research has found that only 10% of drug-induced psychosis cases last longer than six months after use. The majority usually resolve one month following the last time the substance was abused.3

How Dangerous Is Drug-Induced Psychosis?

Due to the nature of drug-induced psychosis symptoms, this condition can pose a significant risk to the people affected and those around them. In addition, the short-term and long-term effects pose a risk of their own, especially without treatment.

Short-Term Effects of Drug-Induced Psychosis

Drug-induced psychosis may not be recognized while the substance is still active in the body. However, as the body begins to metabolize and eliminate the drug, the short-term effects of drug-induced psychosis can become more apparent. These can include:

  • Delusions
  • Hallucinations
  • Social withdrawal
  • Agitation
  • Confusion

Long-Term Effects of Drug-Induced Psychosis

Psychosis can have a lasting impact on the brain and mind, especially when treatment is postponed or avoided altogether. While many of the effects of drug-induced psychosis will fade within a couple of days, others can take weeks, months, or possibly even longer, depending on the severity.

Some of the long-term effects of drug-induced psychosis can include:

  • Structural brain damage
  • Continued hallucinations and delusions
  • Social struggles
  • Development of mental health disorders, such as New Windowpost-traumatic stress disorder

Drug-Induced Psychosis Symptoms

Drug-induced psychosis can lead to a variety of symptoms, many of which are similar to other mental health disorders, such as schizophrenia.


Paranoia is an unrealistic thought or feeling of being threatened, especially when no risk is presented. While it can often be a mild symptom of drug-induced psychosis, it can vary in severity, with more severe instances of paranoia possible.


Delusions are false beliefs. These can be about yourself or your surroundings, including other people. Types of delusions include:

  • Grandeur
  • Erotomania, or delusion of love
  • Somatic
  • Persecutory
  • Jealousy


Hallucinations are false perceptions. They can affect all five senses, meaning people may hear, smell, taste, see, or feel things that aren’t there. Types of hallucinations include:

  • Auditory
  • Visual
  • Olfactory
  • Gustatory
  • Tactile

Anti-Social Behavior

Paranoia, delusions, and hallucinations can make it difficult to connect with friends and loved ones and feel safe in public spaces. As a result, drug-induced psychosis may lead to anti-social behaviors such as avoidance and isolationism. This can also lead to panic attacks and confusion.

Drug-Induced Psychosis Causes and Risks

Drug-induced psychosis can make it difficult for people to differentiate between reality and false beliefs and perceptions caused by psychotic episodes. As a result, it can introduce an elevated risk for dangers such as suicide, violent outbursts, and injury. Because of this, drug-induced psychosis often requires hospitalization.

What Causes Drug-Induced Psychosis?

Drug-induced psychosis typically occurs when the body is introduced to a toxic amount of drugs. This can be caused by taking too much of a single substance or a combination of substances. In addition, this condition can occur during substance withdrawal.

What Drugs Cause Drug-Induced Psychosis?

The drugs that are most often reported to cause psychosis are mind-altering substances, especially cannabis. In fact, recent studies have shown that cannabis can increase the risk of psychosis and has the highest conversion rate to schizophrenia at 47%.4

Nonetheless, many different substances can cause drug-induced psychosis, including:

  • Cannabis

  • Alcohol
  • Amphetamines, such as methamphetamine, ecstasy, and MDMA
  • Stimulants, such as cocaine
  • Hallucinogens, such as LSD, PCP, and psilocybe mushrooms

Risk Factors

There are certain factors that can elevate the risk of drug-induced psychosis. They include:

  • Abnormal brain changes, such as through an injury or stroke
  • Family history of psychotic disorders
  • Brain disorders
  • Brain tumors and cysts

Diagnosis for Drug-Induced Psychosis

Because drug-induced psychosis can mimic other conditions, including psychosis caused by a psychotic disorder, it is important to properly diagnose the condition either through a drug-induced psychosis test or by utilizing drug-induced psychosis diagnostic criteria. Because drug-induced psychosis relies on a substance to be present in the body, that is one of the leading determinate factors when identifying a diagnosis.

Treatment for Drug-Induced Psychosis

While drug-induced psychosis can be distressing, there is treatment available to help.

Drug-Induced Psychosis Treatment Program

Drug-induced psychosis treatment programs combine a New Windowvariety of treatment methods for a multifaceted approach.


The first step is a medically supervised detox, a process that safely eliminates the substance from the body to begin working towards recovery.


The most commonly used and efficient therapy is cognitive behavioral therapy (CBT). CBT helps create a better understanding of how negative thoughts impact the mind and behaviors and actively changes them to more positive ones.


Medication to manage substance withdrawal symptoms, such as cravings, anxiety, depression, and psychosis, can help ensure a safe and more comfortable recovery.

Support Groups
