Definition - What does Opioid mean?
Opioids are a class of drugs that includes both natural opiates derived from the opium plant and synthetic emulators of those drugs. Some medical professionals use the term opioid to distinguish synthetic versions of the drug from their natural counterparts. However, the two terms opiate and opioid are generally used interchangeably.
SureHire explains Opioid
Despite the fact that opioids are highly addictive, they continue to be prescribed for pain relief. Many patients who do not respond to other pain treatments benefit from the use of opioids. The body naturally produces opioids which attach to opioid receptors in the brain. Manufactured opioids attach to these same receptors, blocking pain and calming the body. In addition to relieving pain, these opioids induce feelings of joy or satisfaction.
