What are the side effects of chronic inhalant abuse?
respiratory failure, rhabdomyolysis, and cardiac arrhythmias. Brain imaging studies show diffuse cerebral, cerebellar, and brain stem atrophy with white matter disease
What are side effects of long term toluene abuse
personality changes and cognitive dysfunction. Moreover, long-term exposure damages myelin sheaths of CNS neurons, resulting in ataxia, corticospinal tract signs, nystagmus, or optic nerve dysfunction, similar to patients with multiple sclerosis; however, unlike multiple sclerosis, toluene-induced demyelination is associated with both cognitive and physical impairment.
Where would you find toluene to abuse?
Paint thinner, Airplane glue, Cement solvent
What are notable side effects of nitrous oxide abuse?
Nitrous oxide lacks the qualitative subjective sleepiness, making it unique as it lacks the CNS depressant effects noted with most inhalants. Long-term use has been associated with diffuse polyneuropathy and myelinopathy reminiscent of vitamin B12 deficiency. Nitrous oxide inactivates vitamin B12 (cyanocobalamin) by oxidizing the cobalt within the molecule.
