"Poppers" might permanently cause eye damage.
"Poppers," a slang term for pills containing alkyl nitrite compounds, commonly known as club drugs, are inhaled at discos to enhance the loud throbbing music and flashing lights. They are also used for sexual effects. These compounds appear to be toxic to the fovea of the eye and can also cause visual problems known as maculopathy. Abstention generally results in partial to full recovery.
PositiveTip: Avoidance of popular psychoactive compounds is the best and safest policy.
