Abstrakt: Nitrous oxide (N 2 O), used medically as an anaesthetic, has gained popularity as a recreational drug, with rising prevalence particularly among young adults. While its reinforcing and addictive potential remains debated, N 2 O is proven to be neurotoxic, especially with prolonged, heavy use, which is often unexpected for users. The neurotoxicological mechanism underlying N 2 O-induced neurotoxicity involves inactivation of vitamin B 12 (cobalamin), which disrupts methionine synthesis, essential for maintaining the myelin sheath. This can result in demyelinating diseases, including generalized demyelinating polyneuropathy (GDP). Clinical incidence of N 2 O-induced peripheral neuropathy is largely unknown, although some research suggests it is not uncommon. Treatment includes immediate cessation of N 2 O use and vitamin B 12 supplementation. Although this treatment often reverses damage, residual symptoms such as limb weakness may persist. Additionally, genetic and dietary factors, such as vitamin B 12 deficiency, may heighten individual vulnerability for N 2 O's detrimental effects.
