Some long-term effects are weight loss, muscle weakness, disorientation, hearing loss, limb spasms, bone marrow and central nervous system (including brain) damage, irritability, depression, liver and kidney damage. This is not a full list of the harmful effects of inhalants and please note different inhalants may produce different effects.
Abusing inhalants is compared to playing a game of Russian Roulette. This is because when you inhale you are depriving your body of oxygen. The inhalant causes the heart to beat rapidly and erratically, which in some cases may result in cardiac arrest (Sudden Sniffing Death Syndrome)- may explain why your heart felt like it would stop.
Does anyone know of any evidence out there linking inhalant abuse and cancer?
