Understanding Opioid Drugs: Types, Uses, and Risks

## What Are Opioids? Opioids are a class of drugs that include both legal prescription pain relievers and illegal substances. They work by binding to specific receptors in the brain, spinal cord, and other areas of the body, primarily: * Mu receptors (μ) * Kappa receptors (κ) * Delta receptors (δ) This interaction results in: > Pain reduction, euphoria, and sedation through the inhibition of pain signals and the release of dopamine in the brain's reward centers. ## Types of Opioids ### Natural Opioids Natural opioids, derived from the opium poppy plant (*Papaver somniferum*), include morphine and codeine. These substances have been used for thousands of years and remain important in modern medicine.
