Does nitrous oxide kill brain cells?

Answer 1

Recreational users should be aware, that inhaling nitrous oxide from tanks used in automotive systems is unsafe, because the toxic gas sulfur dioxide is mixed in around 100 ppm, specifically to discourage recreational use.[23] Recreational abuse of the pure gas is also associated with negative health effects. A long term use, can lead to drug addiction. If the gas is inhaled for long-term use in excessive quantities, it has been associated with vitamin B12 deficiency anemia (due to reduced hemopoiesis), neuropathy, tinnitus, and numbness in extremities, unless vitamin B12 supplements are taken to counteract this. Chronic use among pregnant women has been shown to be teratogenic and foetotoxic. Neurotoxicity may also occur from the long term use of nitrous oxide.

Answer 2

Nitrous oxide, commonly known as laughing gas, can temporarily reduce oxygen supply to the brain when inhaled in high concentrations, potentially leading to brain cell damage or death. Prolonged and frequent use of nitrous oxide can have adverse neurological effects, including memory loss, cognitive impairment, and nerve damage.
