Morphine addiction
What is morphine?
Morphine is a powerful opioid painkiller used in medicine to manage severe pain, often after surgery or in cases of terminal illnesses like cancer. It works by blocking pain signals in the brain, providing significant relief for patients who need strong pain management.
In the UK, morphine is classified as a controlled substance under the Misuse of Drugs Act 1971, meaning it can only be prescribed by a doctor for medical purposes.
While highly effective, it must be used with caution due to its potential for addiction and serious side effects if misused.
Is morphine addictive?
Morphine works by binding to opioid receptors in the brain and spinal cord, which blocks pain and creates feelings of euphoria and relaxation. This intense pleasure can make a person want to continue using morphine, even if they don’t need it for pain management anymore.
Over time, the brain starts to rely on morphine to release feel-good chemicals like dopamine, and it becomes harder to feel pleasure without the drug. This leads to tolerance, where the person needs more of the drug to get the same effect. Eventually, dependence sets in, making it difficult to stop using morphine without experiencing withdrawal symptoms like nausea, anxiety or muscle aches.
Because of this, even when used as prescribed, there’s always a risk of developing an addiction to morphine, especially with long-term use or higher doses.
