Long-term or habitual use can lead to severe neurological damage. [3] Nitrous oxide is said to enhance the effects of psychedelics. [6] Since nitrous oxide can cause dizziness, dissociation, and temporary loss of motor control, it is unsafe to inhale while standing up. Safer use can involve inhalation while seated to decrease risks of injury by ...
Administration of nitrous oxide anesthesia can precipitate subacute combined degeneration in people with subclinical vitamin B 12 deficiency, while chronic nitrous oxide exposure can cause it even in persons with normal B 12 levels. Posterior column dysfunction decreases vibratory sensation and proprioception (joint sense).
As a final step, NOS is dephosphorylated yielding nitric oxide (NO), which accumulates in the brain, increasing its oxidative stress. There are several ROS, including superoxide, hydrogen peroxide and hydroxyl, all of which lead to neurotoxicity. Naturally, the body utilizes a defensive mechanism to diminish the fatal effects of the reactive ...
Common examples of neurotoxins include lead, [7] ethanol (drinking alcohol), [8] glutamate, [9] nitric oxide, [10] botulinum toxin (e.g. Botox), [11] tetanus toxin, [12] and tetrodotoxin. [6] Some substances such as nitric oxide and glutamate are in fact essential for proper function of the body and only exert neurotoxic effects at excessive ...
Toxic encephalopathy is a neurologic disorder caused by exposure to neurotoxic organic solvents such as toluene, following exposure to heavy metals such as manganese, as a side effect of melarsoprol treatment for African trypanosomiasis, adverse effects to prescription drugs, or exposure to extreme concentrations of any natural toxin such as cyanotoxins found in shellfish or freshwater ...
Nitrous oxide is thought to be particularly non-toxic, though heavy long-term use can lead to a variety of serious health problems linked to the destruction of vitamin B12 and folic acid. [17] [18] Nitrous oxide "whippets" are small aerosol containers designed for charging whipped cream dispensers.

People with normal vitamin B 12 levels have stores to make the effects of nitrous oxide insignificant, unless exposure is repeated and prolonged (nitrous oxide abuse). Vitamin B 12 levels should be checked in people with risk factors for vitamin B 12 deficiency prior to using nitrous oxide anaesthesia.
