Understanding Dissociative Substances and Their Effects
At Pathways Recovery Center, we believe education is a crucial component of addiction treatment and prevention. Understanding the nature of substances like nitrous oxide (often called “laughing gas”) and similar drugs can help individuals make informed decisions about their health. This article explores drugs that share mechanisms or effects with nitrous oxide, their medical uses, recreational risks, and treatment options.
What is Nitrous Oxide?
Nitrous oxide is a colorless, slightly sweet-smelling gas that has been used medically for over 150 years. In clinical settings, it’s used as:
- A mild sedative in dentistry
- An anesthetic adjunct in surgery
- A pain management tool during brief medical procedures
When used medically, nitrous oxide is always administered with oxygen to prevent oxygen deprivation. It produces rapid effects that include:
- Feelings of relaxation and euphoria
- Mild dissociative effects
- Reduced anxiety
- Analgesic (pain-relieving) properties
Nitrous oxide works by acting as an NMDA receptor antagonist in the brain. According to the National Institute on Drug Abuse (NIDA), dissociative drugs like nitrous oxide “block the action of N-methyl-D-aspartate (NMDA) receptors” which are “part of the brain’s system for transporting glutamate,” creating feelings of detachment from one’s body and environment. At Pathways Recovery Center, we understand how substances like nitrous oxide affect the brain and body, which informs our evidence-based approach to addiction treatment.
Similar Drugs: The NMDA Antagonist Class
Several drugs share nitrous oxide’s mechanism of action as NMDA receptor antagonists. These substances form a category called “dissociative drugs” because they cause users to feel detached from their environment and themselves.
Ketamine
Ketamine is perhaps the most well-known dissociative drug similar to nitrous oxide. Originally developed as an anesthetic, ketamine:
- Is used medically for anesthesia and increasingly for treatment-resistant depression
- Produces more potent dissociative effects than nitrous oxide
- Can create profound alterations in perception and consciousness at higher doses
- Works through the same NMDA receptor blocking mechanism
According to the National Institute on Drug Abuse (NIDA), ketamine and other dissociative drugs affect “the balance of certain chemicals in the brain,” leading to altered perception and feelings of disconnection from one’s body and environment. For more detailed information about ketamine and similar dissociative drugs, visit the NIDA’s resource page on psychedelic and dissociative drugs.
Unlike nitrous oxide’s very short duration (minutes), ketamine’s effects typically last 1-2 hours when used medically.
Phencyclidine (PCP)
PCP is another NMDA receptor antagonist, originally developed as an anesthetic but discontinued due to severe side effects:
- Causes more intense dissociation than either nitrous oxide or ketamine
- Often produces more unpredictable behavior and thought patterns
- Has a much longer duration of action (4-6 hours or more)
- Is rarely used medically today but remains a recreational drug of concern
PCP is chemically related to ketamine but produces stronger and potentially more dangerous effects.
Dextromethorphan (DXM)
DXM is commonly found in over-the-counter cough medicines but at high doses acts as an NMDA antagonist similar to nitrous oxide:
- Produces dissociative effects at doses far above the medical recommendation
- Is more accessible than other dissociatives due to its presence in OTC medications
- Effects can last 3-6 hours, much longer than nitrous oxide
- Can cause significant impairment and health risks when misused
Methoxetamine (MXE)
MXE is a newer synthetic dissociative drug designed to mimic ketamine effects:
- Creates similar dissociative states to other NMDA antagonists
- Often marketed as a “legal” alternative to ketamine
- Has a duration of 5-7 hours
- Carries significant health risks due to limited research on its safety profile
Why Are These Drugs Similar Yet Different?
While all these substances work primarily by blocking NMDA receptors, their effects vary based on:
- Potency: How strongly they bind to NMDA receptors
- Selectivity: Whether they affect other neurotransmitter systems besides glutamate
- Duration: How long they remain active in the body
- Route of administration: How they’re taken affects onset and intensity
Nitrous oxide stands out from other dissociatives because of its:
- Extremely short duration (minutes versus hours)
- Medical safety profile when properly administered
- Rapid elimination from the body
- Primarily inhalation-based route of administration
Health Risks of Dissociative Drugs
All dissociative drugs, including nitrous oxide, carry health risks, especially when misused:
Short-term risks:
- Impaired motor function and coordination
- Nausea and vomiting
- Increased blood pressure
- Respiratory depression (slowed breathing)
- Loss of consciousness
- Accidents and injuries due to impairment
Long-term risks:
- Vitamin B12 deficiency (particularly with nitrous oxide)
- Memory problems
- Psychological dependence
- Bladder and urinary tract issues (especially with ketamine)
- Cognitive impairment with chronic use
According to the Substance Abuse and Mental Health Services Administration (SAMHSA), finding appropriate treatment is crucial for individuals struggling with substance use disorders. Their National Helpline offers 24/7 treatment referral and information services for individuals facing substance use disorders.
Many individuals struggling with dissociative drug use may also experience co-occurring mental health disorders. Our dual diagnosis treatment program specifically addresses these complex cases, providing integrated care for both substance use and mental health concerns.
Therapeutic Uses of NMDA Antagonists
Despite the risks, several NMDA antagonists have legitimate therapeutic applications:
- Ketamine: Used for treatment-resistant depression, PTSD, and chronic pain
- Nitrous oxide: Dental procedures, brief surgeries, and labor pain management
- DXM: Cough suppression at appropriate doses
Recent research has shown promising results for ketamine and nitrous oxide in treating depression, particularly in cases where traditional antidepressants have failed.
Understanding the distinction between therapeutic use and misuse is important. At Pathways Recovery Center, our treatment model incorporates this nuanced understanding of how substances affect the brain, allowing us to develop personalized recovery plans for each client.
Treatment for Dissociative Drug Misuse
At Pathways Recovery Center, we provide comprehensive treatment for individuals struggling with dissociative drug use, including:
- Medically supervised detoxification to manage withdrawal symptoms
- Residential treatment for immersive recovery
- Dual diagnosis care addressing both substance use and mental health
- Individual and group therapy targeting the underlying causes of substance use
- Aftercare planning to maintain long-term sobriety
Understanding the Appeal and the Dangers
Dissociative drugs like nitrous oxide appeal to users because they can produce:
- Euphoria and altered states of consciousness
- Temporary escape from emotional or physical pain
- Novel sensory experiences
- In medical settings, therapeutic relief from pain or anxiety
However, these temporary effects come with significant risks, particularly when these substances are misused or obtained outside medical settings.
According to the Nevada County Department of Health, hypoxia (oxygen deprivation) from nitrous oxide use can be fatal in rare instances, and while the substance is not physically addictive, psychological dependence can develop. The Centers for Disease Control and Prevention (CDC) recommends seeking professional help for substance use issues through resources like the SAMHSA treatment locator.
For many people, what begins as recreational use can develop into a substance use disorder requiring professional intervention. The residential inpatient treatment at Pathways Recovery Center provides a safe, structured environment away from triggers and access to substances, creating an ideal setting for initial recovery from dissociative drug use.
