"Opioid" refers to a class of drugs that are used to reduce pain. They act on opioid receptors in the brain and body, mimicking the effects of naturally occurring pain-relieving chemicals. Opioids can be natural, derived from the opium poppy (such as morphine and codeine), or synthetic and semi-synthetic, like oxycodone, hydrocodone, and fentanyl.
While opioids can be effective for pain management, they also carry a risk of addiction, dependence, and overdose. The misuse and over-prescription of opioids have led to significant public health issues, commonly referred to as the opioid crisis in many regions, particularly in the United States.
In summary, opioids are powerful pain-relieving medications that must be used responsibly due to their potential for abuse and serious side effects.
