"opiate" 的定义和意义

What is an "opiate"?

An opiate is a drug made from opium, a substance taken from the poppy plant. Opiates include both natural substances and artificial drugs. They are commonly used for pain relief because of their ability to attach to specific receptors in the brain and spinal cord, reducing the sensation of pain. However, they also cause drowsiness, constipation, and can lead to feelings of extreme joy and excitement. Misuse of opiates can result in addiction, respiratory issues, overdose, and other serious health problems. Because of their addictive nature and potential for abuse, opiates are strictly controlled substances in most countries.
