Heroin nodding is a dangerous and common state of sedation, drowsiness, or altered consciousness caused by the use of heroin. This deep sleep-like state is often accompanied by an intense feeling of euphoria or relaxation, as well as slurred speech, confusion, and disorientation. However, heroin nodding is not just a harmless side effect. It can lead to dangerous activities such as driving a car while under the influence, resulting in a higher risk of injury or death. Moreover, the body’s respiratory rate decreases during this state, increasing the risk of overdose. Heroin nodding is caused by the drug’s ability to depress central nervous system activity, including breathing rate, heart rate, and body temperature. In extreme cases, this can result in coma or death due to respiratory failure.
