How Do I Know If Someone Is On Morphine?
Morphine is a drug that’s used to treat pain and is classified as an analgesic opiate. It’s used as a prescription pain relief treatment option, but it’s also used recreationally. Even when people are prescribed to morphine, it does carry a chance of addictiveness and physical dependence.

Morphine is derived from the poppy plant and is used for clinical purposes for pain management, primarily in instances of post-surgery recovery or terminal cancer.
It can also be used clinically in situations where there is a significant trauma or injury that occurs, and brand names of morphine include MSiR, MS-Contin, and Roxanol, among others.
Legally, morphine is classified as a Schedule I drug in the U.S.
This narcotic drug can be taken as an extended-release medication, and it’s not intended for use on an as-needed basis. Morphine can be taken by mouth in the form of a tablet or syrup, but the most common way it’s given is by injection.
When someone takes morphine, they feel a euphoric rush, which is the case with most opioids, and then they will tend to move in and out of being awake and then drowsy or periods of nodding off.
Signs someone is on morphine and has developed a tolerance includes taking higher doses than what they’re prescribed for and also taking it more often.
If someone is on morphine recreationally, they will have to take higher doses to achieve the euphoric rush or high that comes with use of this prescription painkiller.

A moderate disorder would include four to five of the above, and a severe problem would include six or more.
If you know someone who is taking morphine with or without a prescription and you’re worried they’re abusing this prescription drug, it’s important to monitor their behavior. People who are on morphine will also often become secretive, absent for unexplained reasons, lack motivation and will display personality changes such as mood swings.
