Is It Possible to Overdose on Nitrous Oxide? What Is the Lethal Amount?

What is nitrous oxide, and how dangerous is it?

Nitrous oxide (also known as laughing gas) was discovered in the late 1700s and has been utilised for therapeutic purposes for many years. It’s a tiny inorganic compound with a variety of applications outside of medicine. It’s widely employed in the food processing, semiconductor, and even auto racing industries. Because it is a result of combustion, nitrous oxide is also considered a pollution.

Individuals who inhale nitrous oxide gases from a variety of sources, including commercial whipped cream dispensers (commonly known as “whippets”) and other similar containers, are also abusing the gas. Replacement nitrous oxide containers for these commercial-grade goods are widely accessible and possessing them is not unlawful. Furthermore, nitrous oxide is found in a variety of over-the-counter goods that can be found in any local supermarket, such as vegetable spray, culinary sprays, and so on.

How Long Does Laughing Gas Keep You Laughing?

Nitrous oxide is typically absorbed by the lungs because it is a gas. Laughing gas has a very short half-life of about five minutes, and it is mostly expelled by breathing.

Because of the substance’s incredibly short half-life, the psychoactive effects are fleeting and powerful, leading to people bingeing on the gas repeatedly to maintain the effects. The use of nitrous oxide is not thought to induce physical reliance, but it may cause emotional or psychological reliance, such that individuals may feel compelled to take it to cope with stress, worry, or everyday problems.

What Are the Symptoms of an Overdose of Nitrous Oxide?

The following are signs of hazardous exposure, including overdose:

  • Irritation of the eyes, nose, and/or throat is a common ailment.
  • Wheezing or a cough that is getting worse
  • Seizures or severe respiratory depression, both of which are potentially lethal.
  • Chest constriction or choking
  • Dizziness, lightheadedness, or headache
  • Breathing problems (dyspnea)
  • Fingers, toes, or lips that are bluish
  • Changes in blood pressure, rapid heart rate, and the risk of a heart attack or stroke
  • Psychosis (hallucinations and/or delusions) is a condition in which a person has hallucinations and/or delusions.

Because this is a gas, no recommended or stated dosage for toxicity or overdose are available. The World Health Organization (WHO) has established guidelines for the safe use of nitrous oxide in both chronic and acute exposures (acute exposure being for the use of medicinal reasons and not designed to specify exposures associated with recreational abuse of the substance).

The maximum nitrous oxide exposure for chronic exposure is 20 parts per billion (representing a ratio between nitrous oxide and breathable air), and the maximum acute exposure is 100 parts per billion for one hour.

Individuals who abuse laughing gas by inhaling containers of it easily exceed this safe ratio, resulting in toxic and overdose effects after several minutes of continued exposure; however, due to the drug’s short half-life, overexposure to nitrous oxide should dissipate quickly once the person stops breathing in the substance and breathes air. Continuing to breath the drug for more than a few minutes can cause serious health problems. Chronically misusing nitrous oxide (inhaling it on a daily basis) can result in major chronic difficulties, including hazardous exposure.

Individuals who inhale excessively concentrated volumes of nitrous oxide and do not breathe sufficient amounts of oxygen could potentially die if they suffer major brain damage as a result of a shortage of oxygen to the brain.

What Are Nitrous Oxide’s Medical Applications?

  • During surgical treatments, particularly dental surgery, for anaesthetic.
  • For the alleviation of persistent pain, such as that caused by many types of cancer.
  • For children receiving arthritic pain injections
  • Other medical treatments that are modest

Individuals who inhale overly concentrated doses of nitrous oxide and do not breathe enough oxygen may die if they suffer serious brain damage as a result of a lack of oxygen in the brain.

What Are the Medical Uses of Nitrous Oxide?

  • For anaesthetic use during surgical procedures, particularly dental surgery.
  • For the relief of chronic pain, such as that induced by a variety of cancers.
  • Injections for arthritic discomfort in youngsters
  • Other less-expensive medical procedures

With only a few exceptions, the gas is considered to be relatively safe:

Abuse of nitrous oxide is a serious problem. As previously said, it is rather easy to come by, and there is no set age limit for purchasing nitrous oxide canisters known as whippets, cream chargers, and so on. Furthermore, people can buy nitrous oxide-containing goods, such as whipped cream, in grocery stores and inhale the gas.

How Does Nitrous Oxide Make You Feel?

  • Feelings of extreme euphoria
  • Experiencing periods of “deep pondering” or becoming more abstract
  • An increase of positive emotions
  • A light burst of energy
  • Inhibitions are lost.

What Are Some Negative Nitrous Oxide Reactions?

  • Dizziness
  • It should not be used by people who have serious respiratory problems.
  • It should not be used in people who have had intraocular surgery with an intraocular gas.
  • When used by those with a history of heart disease, stroke, or vitamin B12 deficiency, it should be used with caution.

Welders, firefighters, military personnel, and others who operate in occupations where nitrous oxide is regularly inhaled are at risk for difficulties linked with long-term exposure, as are chronic nitrous oxide abusers. Organic material, such as corn and other grains, may also produce nitrous oxide as a byproduct. Farmers may be at danger of chronic exposure if these are stored in silos and ferment.

In a research article published in the American Journal of Addictions in 2016, an assessment of the available case studies revealed the following:

  • There were 29 incidences of abuse that resulted in death.
  • Neurological problems were frequently linked to fatalities.
  • There were 11 incidences of psychosis linked to abuse that were documented.
  • Abuse of nitrous oxide has been linked to a slew of additional health problems.

The authors concluded that this is a significant concern due to the difficulty in medically recognising the toxicity associated with nitrous oxide usage. Clinicians should familiarise themselves with the symptoms in order to recognise them.
