Published: June 2023

Recreational use of nitrous oxide (NO) has increased rapidly in recent years and is now the second most commonly used recreational drug among young people in the UK. There has been a corresponding rise in cases of nitrous oxide-induced subacute combined degeneration of the cord (NO-SACD), a pattern of myeloneuropathy usually associated with severe vitamin B deficiency. This can cause serious and permanent disability in young people but, if recognised early, may be effectively treated. All neurologists should be aware of NO-SACD and its treatment; however, there are currently no agreed guidelines. Based on our experience in East London, an area of high NO use, we provide practical advice on its recognition, investigation and treatment.

Whippets abuse, prevalent among recreational drug users, poses significant health risks, particularly through the inactivation of vitamin B12 by nitrous oxide (NO). This deficiency can lead to myelopathy, resulting in serious neurological complications. We present two female patients, aged 22 and 35, with a history of regular whippet use over the past three years, who exhibited clinical symptoms of myelopathy, including motor weakness, rigidity, sensory changes, and gait abnormalities.

Article Synopsis
  • Nitrous oxide, commonly used as an anesthetic, is increasingly abused recreationally, leading to neurological issues in users.
  • A study reviewed seven patients aged 19-32 who inhaled nitrous oxide and subsequently experienced ataxia and sensory dysfunction, with some showing coexisting encephalopathy.
  • Although patients had poor short-term outcomes, most showed significant recovery after more than six months, indicating potential long-term improvement despite initial symptoms.

Under standard conditions, nitrous oxide (NO) manifests as a colorless, odorless gas with a mildly sweet taste. The compound finds applications in various fields, including its use as an aerosol propellants, an accelerant in motor racing, and an anesthetic in surgical procedures and dentistry. Unfortunately, the recreational misuse of NO has become prevalent among young individuals due to its euphoric and hallucinogenic effects.

Introduction: Cases of nitrous oxide (NO)-induced myeloneuropathy are increasing at UK hospitals. At our centre, a dedicated ambulatory care pathway, endorsed nationally, was established to treat and monitor patients with NO-myeloneuropathy in 2021 and refined through three audit cycles. We analysed the outcomes of patients on this pathway to better understand factors associated with non-engagement.

Longitudinal follow-up and prognostic factors in nitrous oxide-induced neuropathy.

Reference Center for Neuromuscular Diseases and ALS, La Timone University Hospital, Aix-Marseille University, Marseille, France.

Background And Aim: Recreational use of nitrous oxide (NO) has been associated with the development of severe nitrous oxide-induced neuropathy (NOn). Follow-up of these patients poses challenges, and their clinical progression remains largely unknown. The identification of prognostic factors is made difficult by the lack of standardized longitudinal assessments in most studies.
