Heroin quickly binds to opioid receptors in the brain, creating an intense sense of euphoria when these receptors get an adequate supply of the drug. In a very short period of time, the brain requires higher doses at more frequent intervals. Eventually, these changes cause the brain to trick the body when users stop using, creating an intense, sickening, and painful withdrawal experience. Some of the most common heroin withdrawal symptoms include, but are not limited to:
- Nausea and Vomiting
- Insomnia and Bad Dreams
- Hot and Cold Flashes
- Extreme Perspiration
- Severe Joint and Muscle Pain
- Watery Discharge from Eyes and Nose
The heroin withdrawal timeline is different for every patient; however, heroin and other short-acting opioids typically have a duration of around 4 to 10 days, and occur around 8 to 24 hours after the last cycle of use.
