Laughing gas (Nitrous oxide)
Laughing gas, also known as nitrous oxide (N2O), is a colourless and odourless gas that has both medical and recreational uses. It has a long history of use for its anaesthetic and analgesic properties in dentistry and medical procedures.
Recreationally, nitrous oxide is sometimes used for its euphoric and dissociative effects. It is typically inhaled from small canisters or balloons, and the effects are short-lived, lasting only a few minutes. Nitrous oxide is commonly referred to as “laughing gas” because it can induce laughter and a sense of lightheadedness or giddiness.
Nitrous oxide acts as a central nervous system depressant and primarily affects the brain’s neurotransmitters, including inhibiting the action of NMDA receptors. It is believed to induce its effects through the modulation of several neurotransmitter systems, including the release of endogenous opioids.
When used recreationally, nitrous oxide can cause feelings of euphoria, relaxation, and distortions in sensory perception. Some users may experience mild hallucinations or changes in the perception of sound and touch. It is important to note that prolonged or excessive use of nitrous oxide can be dangerous and lead to oxygen deprivation, which can result in serious health complications.
Nitrous oxide is commonly used in medical settings and is considered safe when administered by trained professionals for appropriate medical purposes. However, recreational use of nitrous oxide can carry risks. Inhaling nitrous oxide directly from pressurised canisters can cause injury due to the extreme cold temperature of the gas or the lack of oxygen if used in an enclosed space.
Furthermore, frequent or excessive use of nitrous oxide can lead to vitamin B12 deficiency, which can cause nerve damage and other health problems. Additionally, using nitrous oxide while engaging in activities that require coordination and judgment, such as driving, can be extremely dangerous and is strongly discouraged.
If you have further questions or concerns about nitrous oxide, it is advisable to consult with a healthcare professional or a substance abuse specialist who can provide more specific information and guidance.
