Isobutyl nitrite, also known as 2-methylpropyl nitrite, is a popper that has been used for decades as a recreational drug. The drug induces a short-lived, euphoric high, and has been commonly used in the party and club scenes. However, due to its negative side effects on health, including dizziness, headache, and increased blood pressure, it is now banned in many countries. Some of the synonyms for isobutyl nitrite include liquid gold, jungle juice, rush, locker room, and poppers. Despite their different names, these poppers all contain isobutyl nitrite as their primary ingredient and should be used with caution to avoid negative health outcomes.
