Drug-Induced Psychosis: Signs, Symptoms & Treatment Options

Psychosis is a mental health condition that alters one’s perception of reality, leading to symptoms like hallucinations, delusions and disorganized thinking. While psychosis can occur in psychiatric disorders such as schizophrenia or schizoaffective disorder, it can also happen as a direct result of substance use. This phenomenon is known as drug-induced psychosis or substance-induced psychosis. Because psychosis profoundly affects a person’s thoughts and behaviors, it can interfere with daily functioning, relationships and overall well-being. Early recognition and effective treatment are therefore essential for individuals experiencing this condition.

In this article, we will explore the different aspects of drug-induced psychosis, including what it entails, which substances commonly lead to it, and how to identify the telltale signs of a psychotic episode stemming from various drug classes. We will also discuss the potential mechanisms behind this phenomenon, as well as available treatment options. Our goal is to provide a clear and comprehensive overview so that those affected by this condition can get the help they need from a trusted facility like The Recovery Village Salem or another reputable resource.

What Is Drug-Induced Psychosis?

Drug-induced psychosis is a form of psychosis that arises either during or soon after the use of certain substances. These substances can range from prescription medications to illicit drugs. The primary feature of this disorder is that symptoms of psychosis appear more or less during periods of intoxication, withdrawal or after prolonged use of a specific substance. Symptoms typically include:

• Hallucinations (seeing, hearing or feeling things that are not actually present)
• Delusions (false beliefs not grounded in reality)
• Disorganized thinking or speech
• Paranoia and heightened suspiciousness
• Erratic or unpredictable behavior

While many psychiatric conditions can result in similar symptoms, one hallmark of drug-induced psychosis is that the symptoms are either initiated or exacerbated by substance use and often subside once the substance is out of the body. However, repeated or severe substance use can sometimes trigger long-term psychotic conditions that persist even after cessation. This underscores the importance of immediate evaluation and treatment for anyone experiencing a psychotic episode related to drug use.

How Does Substance Use Lead to Psychosis?

Substance-induced psychosis primarily stems from chemical changes in the brain triggered by drugs. Certain substances can amplify or disrupt neurotransmitters such as dopamine, serotonin, glutamate or GABA. These alterations in brain chemistry can cause hallucinations, delusions and other psychotic symptoms.

For example, stimulants like cocaine and methamphetamine can greatly increase dopamine levels in the brain, thereby pushing the individual’s perception of reality to a breaking point. On the other hand, hallucinogens disrupt serotonin signaling, leading to intense sensory distortions and hallucinations. Depending on the substance, dosage, frequency of use and an individual’s baseline mental health, psychosis may set in temporarily or evolve into a more persistent issue.

Which Drugs Can Lead to Drug-Induced Psychosis?

While any mind-altering substance has the potential to trigger or exacerbate psychosis in vulnerable individuals, certain drug classes carry a higher risk. These include:

• Stimulants: Cocaine, methamphetamine, amphetamines (including certain ADHD medications when misused)
• Depressants: Alcohol, benzodiazepines, barbiturates (psychosis often appears during withdrawal)
• Cannabis (Marijuana): High THC strains or synthetic cannabinoids (e.g., “Spice” or “K2”)
• Hallucinogens: LSD, psilocybin, mescaline, DMT
• Dissociatives: PCP, ketamine, dextromethorphan (DXM)
• Prescription Medications: Corticosteroids, anticholinergics or certain antidepressants in rare cases

Not everyone who uses these drugs will develop psychosis. However, some individuals are genetically or psychologically more susceptible to this effect, particularly those with a personal or family history of psychotic disorders, or with existing mood or anxiety disorders. Recognizing the interplay between substance use and mental health is critical for preventing and managing drug-induced psychosis.

Signs and Symptoms of Drug-Induced Psychosis

The symptoms of drug-induced psychosis can vary based on the type of drug used, the individual’s physiology and mental health and the timing of intoxication or withdrawal. While some general signs like hallucinations, delusions and paranoia can be consistent across the board, the specific presentation may differ for stimulants, depressants, marijuana or hallucinogens.

It is worth noting that the onset of psychosis is not always immediate. In some cases, prolonged or chronic use of a substance gradually accumulates negative effects on the brain. In other scenarios, abrupt discontinuation of a substance can lead to psychosis as part of withdrawal. Below, we outline the signs and symptoms commonly associated with different substances.

Signs of Psychosis From Stimulants

Stimulants such as cocaine, methamphetamine and amphetamines are notorious for inducing psychosis in heavy or chronic users. Key symptoms often include:

• Hallucinations: Users may report tactile hallucinations, such as feeling bugs crawling under their skin (“coke bugs” or “meth mites”), or auditory hallucinations like incessant whispering or ringing.
• Paranoia: Individuals might become hypervigilant, constantly feeling that they are being watched, followed or conspired against.
• Grandiosity or delusions: A person might believe they possess extraordinary powers or are the target of a grand conspiracy.
• Agitation and aggressiveness: Heightened energy levels can morph into irritability, aggression or violent behavior.
• Insomnia: Heavy stimulant use can result in days of little to no sleep, exacerbating mental distress and delusional thinking.

Psychotic symptoms in stimulant users can be severe enough to require immediate intervention. The combination of paranoia, impulsivity and delusions can lead to harmful or even life-threatening scenarios.

Signs of Psychosis From Depressants

While the term “depressant” can be misleading when it comes to psychosis, alcohol, benzodiazepines and other CNS depressants may trigger psychotic symptoms, especially during withdrawal. Some hallmark symptoms include:

• Delirium Tremens (DTs): In severe alcohol withdrawal, individuals may experience delirium marked by severe confusion, hallucinations, tremors, agitation and disorientation.
• Visual hallucinations: Alcohol withdrawal in particular is often accompanied by vivid, sometimes distressing visual hallucinations.
• Paranoid delusions: Both alcohol and benzodiazepine withdrawal can foster an irrational suspicion or paranoia.
• Mood instability: Irritability, anxiety, depression and wild mood swings may accompany psychotic features.
• Physical signs: Tremors, sweating, rapid heart rate and high blood pressure often co-occur with psychosis during withdrawal periods.

Withdrawal-induced psychosis can be dangerous, as individuals might feel out of control and unable to differentiate between reality and hallucinations. In severe cases, medical supervision is necessary to prevent complications like seizures and cardiovascular collapse.

Signs of Psychosis From Marijuana

Marijuana has historically been perceived as a mild or “soft” drug, but heavy or high-potency use, particularly strains high in THC, can lead to or worsen psychotic symptoms. Signs of marijuana-induced psychosis may include:

• Paranoia: This is one of the most commonly reported symptoms of marijuana-induced psychosis. Users may believe they are under surveillance or in danger.
• Heightened anxiety: Excessive worry or panic attacks often accompany psychosis triggered by marijuana.
• Hallucinations: While typically less intense than those from stimulants or hallucinogens, some individuals experience vivid sensory distortions or auditory hallucinations.
• Disorganized thought patterns: Racing thoughts or an inability to concentrate may worsen until they manifest as disorganized speech or behavior.
• Time distortion: Marijuana can alter perception of time, which may become more pronounced and distressing in psychosis.

Although many individuals may use marijuana without experiencing psychosis, those with underlying mental health vulnerabilities or a family history of psychotic disorders face a higher risk.

Signs of Psychosis From Hallucinogens and Dissociatives

Substances like LSD, psilocybin (magic mushrooms), mescaline, PCP and ketamine can cause profound changes in perception, sense of self and reality. While many people seek these substances for psychedelic experiences, some develop acute or even long-lasting psychotic symptoms. Signs can include:

• Intense visual hallucinations: Colorful, geometric and kaleidoscopic visions are common, sometimes morphing into terrifying or threatening images.
• Audio or tactile distortions: Users may experience heightened or distorted sounds or body sensations.
• Out-of-body experiences: Dissociatives like PCP or ketamine can make people feel disconnected from their bodies or environment, contributing to paranoia or delusional thinking.
• Severe mood swings: Shifting rapidly between euphoria and despair, individuals may become highly unpredictable or unstable.
• “Bad trip” phenomena: Extreme distress, fear of death or losing one’s mind can occur, sometimes persisting after the immediate effects of the drug wear off.

While some people recover from hallucinogen-induced psychosis fairly quickly, others may develop prolonged symptoms in the form of persistent psychosis or hallucinogen persisting perception disorder (HPPD). Immediate treatment and ongoing support can help reduce the risk of chronic psychosis.

How Does Drug Use Lead to Psychosis?

From a neurobiological perspective, drugs that induce psychosis often do so by overstimulating or dysregulating neurotransmitter pathways in the brain. Dopamine is frequently implicated in psychosis, with substances like cocaine and methamphetamine dramatically elevating dopamine levels. This overflow can overstimulate reward circuits and frontal brain regions, leading to delusions, hallucinations and erratic behavior.

However, the influence extends beyond dopamine. Serotonin, implicated in mood regulation and perception, is disturbed significantly by hallucinogens like LSD and psilocybin, resulting in altered states of consciousness. Glutamate, a central excitatory neurotransmitter, is disrupted by dissociatives such as ketamine and PCP, often manifesting as dissociation, hallucinations and bizarre thoughts. Meanwhile, during withdrawal from depressants such as alcohol or benzodiazepines, the brain’s GABA levels can plummet, prompting a hyperactive state that may include paranoia and hallucinations.

Additionally, psychological and environmental factors can amplify or mitigate the effects of these neurotransmitter changes. Genetics, stress, unresolved trauma, social isolation and other mental health disorders can all shape how someone experiences a substance and whether that experience escalates into psychosis. Thus, while chemical imbalances in the brain are the immediate cause, the interplay of biological, psychological and social factors ultimately determines whether a person develops a substance-induced psychotic episode.

Treatment Options for Substance-Induced Psychosis

If you or someone you love is experiencing signs of drug-induced psychosis, seeking professional help is vital. Treatment often involves a combination of medical intervention, therapeutic support and long-term rehabilitation. Below, we outline common interventions:

• Medical Stabilization
  
  • Detoxification: The first step often involves ensuring the substance is safely removed from the body. This could require a medical detox program, especially for alcohol and benzodiazepines withdrawal, where sudden cessation can be life-threatening without medical oversight.
  • Medication management: Antipsychotic medications (e.g., risperidone, olanzapine) or benzodiazepines may be used to control acute psychotic symptoms and agitation. In cases of withdrawal-induced psychosis, additional supportive medications to alleviate withdrawal symptoms might be prescribed.
• Psychiatric Assessment and Dual Diagnosis
  
  • Mental health evaluation: A thorough psychiatric exam can determine if a co-occurring mental health disorder (e.g., schizophrenia, bipolar disorder, major depression) plays a role.
  • Dual-diagnosis treatment: When a person has both substance use issues and a mental health disorder, a dual diagnosis program is essential. Comprehensive treatment addresses both conditions simultaneously for the best outcomes.
• Behavioral Therapies
  
  • Cognitive Behavioral Therapy (CBT): CBT can help individuals recognize and reframe distorted thoughts. This is particularly beneficial for those prone to paranoid or delusional thinking.
  • Motivational Interviewing (MI): MI aims to strengthen a person’s motivation and commitment to overcoming substance use and sustaining recovery efforts.
  • Contingency Management: Some treatment settings use incentive-based strategies to reward positive behaviors, like maintaining sobriety or adhering to medication plans.
• Individual and Group Counseling
  
  • Psychoeducation: Learning about how substances affect the brain, how to identify triggers and how to manage cravings is crucial for long-term recovery.
  • Support groups: Group therapy or peer-support programs (e.g., 12-step programs or SMART Recovery) can help individuals feel understood, build social support and maintain accountability.
• Aftercare Planning and Relapse Prevention
  
  • Ongoing therapy: Once the acute phase of psychosis subsides, continued therapy (individual, group or family therapy) can reinforce coping skills and prevent relapse.
  • Lifestyle adjustments: Incorporating stress-reduction techniques such as meditation, exercise and balanced sleep schedules is key to sustaining recovery.
  • Medication monitoring: For those on antipsychotics or other psychiatric medications, regular check-ins with a psychiatrist ensure proper dosage and management of any side effects.
• Family Involvement
  
  • Family therapy: Educating and involving loved ones in the recovery process can help rebuild trust and provide a supportive home environment.
  • Community resources: Connecting with local and online communities can help families access educational resources, support groups and additional healthcare referrals.
