Why does heroin make me hiccup?

Heroin can lead to hiccups due to its effects on the central nervous system, which may disrupt normal respiratory patterns and irritate the diaphragm. Additionally, the drug can cause gastrointestinal issues, leading to increased pressure in the abdomen that may trigger hiccups. Individual reactions to heroin can vary, so not everyone will experience this side effect. If hiccups persist or cause concern, it’s important to consult a medical professional.
