Which of these symptoms are associated with heroin overdose?

The symptoms associated with heroin overdose are characterized by critical physiological changes that can be life-threatening. Slow and shallow breathing is one of the hallmark signs of a heroin overdose, as heroin is an opioid that significantly depresses the respiratory system. This can lead to a reduced oxygen supply to the body, which is critical in an overdose situation.

Clammy skin is another symptom that can indicate an overdose, often resulting from the body entering into a state of shock or distress due to the effects of the drug. This can coincide with other symptoms, such as respiratory depression.

Convulsions, although not as commonly highlighted, may occur in severe cases or in conjunction with other medical issues that arise due to inadequate oxygenation. Together, these symptoms highlight the dangerous impact of heroin on the body and necessitate urgent medical intervention.

The other options include symptoms that are more associated with other types of drug reactions or behavioral responses rather than the physiological effects specifically linked to heroin overdose.
