Which drug's withdrawal symptoms include vomiting, insomnia, and nausea?

Heroin, being an opioid, leads to a range of withdrawal symptoms when a person stops using it after a period of regular consumption. The body becomes physically dependent on the drug, and the abrupt cessation triggers a variety of distressing symptoms as it readjusts to functioning without the substance. Common withdrawal symptoms of heroin include vomiting, insomnia, and nausea, among others.

These symptoms occur as the brain's neurotransmitter levels, which were altered by the drug's influence, start to normalize in the absence of heroin. This results in a strong physical discomfort that can last for days to weeks, depending on the severity of the dependence. Understanding the withdrawal process is crucial for law enforcement and healthcare professionals as they deal with individuals who may be suffering from substance use disorders.

Other substances listed, such as cocaine and meth, can also have their own withdrawal symptoms, but they differ significantly in nature. Alcohol withdrawal has its own severe complications and symptoms but should not be confused with the unique opioid withdrawal symptoms experienced by those addicted to heroin.
