Oxidative Stress In Morphine Addiction
In addition, morphine also affected other oxidative stress-related proteins. Long-term treatment with morphine not only increased the MDA level, but also decreased activities of SOD, glutathione-s-transfrase , and catalase in the liver of rats . Morphine accelerated the disease progression of HIV-infection in macaques due to the deteriorated oxidative stress, including the 50% drop of CAT and SOD . In rat primary neuronal striatal cells, three oxidative stress-related proteins – glyceraldehyde-3-phosphate dehydrogenase , dihydrolipoyl dehydrogenase , and aldehyde dehydrogenase – were significantly upregulated after morphine administration . Proteomic analysis demonstrated that oxidative stress-related proteins, such as peroxiredoxin-2 and Heat shock protein 70 , were significantly decreased in the NAc of morphine-dependent monkeys .

Morphine Effects And Abuse
As a Narcotic drug, Morphine is often abused for its pleasurable effects. Those suffering from chronic pain have the potential to misuse their medication, which increases their likelihood of developing a substance use disorder.
Common effects of Morphine include:
- False or unusual sense of well-being
- Relaxed or calm feeling
Any time someone uses Morphine without a prescription, it is considered abuse. Although it is a legal substance when prescribed, it is a heavily regulated one. Possession of Morphine without a prescription is a criminal offense, the degree of which varies based on the jurisdiction and the amount of the drug in possession.
Those who abuse Morphine in high doses put themselves at risk of overdosing. Signs of a Morphine overdose include slurred speech, inattention, intense drowsiness, fever, elevated blood pressure, increased thirst, lower back or side pain, decreased responsiveness, extreme sleepiness, swelling of the face and extremities, lack of movement, slowed breathing, muscle cramps, spasms, pain, and stiffness. This is because Morphine depresses the central nervous system . Overdosing on Morphine can lead to unconsciousness, coma, or slowed breathing to the point of death.

The Changed Set Point Model
The changed set point model of drug addiction has several variants based on the altered neurobiology of the DA neurons in the VTA and of the NA neurons of the LC during the early phases of withdrawal and abstinence. The basic idea is that drug abuse alters a biological or physiological setting or baseline. One variant, by , is based on the idea that neurons of the mesolimbic reward pathways are naturally set to release enough DA in the NAc to produce a normal level of pleasure. Koob and LeMoal suggest that opioids cause addiction by initiating a vicious cycle of changing this set point such that the release of DA is reduced when normally pleasurable activities occur and opioids are not present. Similarly, a change in set point occurs in the LC, but in the opposite direction, such that NA release is increased during withdrawal, as described above. Under this model, both the positive and negative aspects of drug addiction are accounted for.
Emerging Trends In Substance Misuse:
- MethamphetamineIn 2019, NSDUH data show that approximately 2;million people used methamphetamine in the past year. Approximately 1;million people had a methamphetamine use disorder, which was higher than the percentage in 2016, but similar to the percentages in 2015 and 2018. The National Institute on Drug Abuse reports that overdose death rates involving methamphetamine have quadrupled from 2011 to 2017. Frequent meth use is associated with mood disturbances, hallucinations, and paranoia.
- CocaineIn 2019, NSDUH data show an estimated 5.5 million people aged 12 or older were past users of cocaine, including about 778,000 users of crack. The CDC reports that overdose deaths involving have increased by one-third from 2016 to 2017. In the short term, cocaine use can result in increased blood pressure, restlessness, and irritability. In the long term, severe medical complications of cocaine use include heart attacks, seizures, and abdominal pain.
- KratomIn 2019, NSDUH data show that about 825,000;people had used Kratom;in the past month. Kratom is a tropical plant that grows naturally in Southeast Asia with leaves that can have psychotropic effects by affecting opioid brain receptors. It is currently unregulated and has risk of abuse and dependence. The National Institute on Drug Abuse reports that health effects of Kratom can include nausea, itching, seizures, and hallucinations.

How Fast Can You Develop A Morphine Addiction
If youve received a morphine injection, you know that it can cause a rush of euphoria. Not only does it help with physical pain, but it can make you forget about emotional distress too. And that can be very addictive.
Morphine can also change your brains physical chemistry. Its an opiate and it interacts with receptors in the brain to lessen the sensation of pain throughout the nervous system.
- First, it floods the brain with neurochemicals, including dopamine and serotonin. These chemicals are what give people a euphoric, high sensation.
- Then, over time, the brain adapts to the presence of these chemicals and starts sending signals that it needs more of them to feel normal. This adjustment to the presence of morphine as the brains new normal, or homeostasis, is the first big marker of addiction.
Everyone is different. Many people can tolerate receiving morphine for pain management without becoming addicted. Some people are more sensitive to the drugs effects. Some are particularly genetically vulnerable to opiate addiction. But everyone has at least some potential to become addicted to the drug, and the longer you are on it, the more likely you are to develop a physical dependence.
- Frequent fatigue and/or mental confusion
- Gastrointestinal problems, such as constipation and diarrhea
- Nausea, possibly with vomiting
- Trouble breathing and maintaining equilibrium

How Long Does It Take To Feel Effects
Morphine is prescribed in several different forms, including a liquid solution and extended-release tablets and capsules. The timing of dosage is important for it to reach therapeutic levels but not a level that could cause an overdose.
Different formulations of morphine have different onset times and durations:
- Extended-release morphine delivers the dosage in stages, the effects lasting for 1224 hours
- Instant-release morphine’s effects begin within 15 to 60 minutes and last 4 to 6 hours
Other effects of morphine besides pain suppression include:
- Altered mental status
The body becomes tolerant when morphine is used over time and dosage may need to be adjusted to provide the desired effects. Morphine also leads to dependence and the body can have withdrawal symptoms if it is stopped. For this reason, it is important to follow the schedule provided by your doctor when it is decided to stop morphine.

Why Don’t Patients With Pain Become Addicted To Morphine
Oncology NEWS International
GLASGOW-Pain specialists continually stress the message that clinicians should not fear prescribing adequate doses of opioids for pain patients, since such patients are not at risk of becoming “addicted.”
GLASGOW-Pain specialists continually stress the message that cliniciansshould not fear prescribing adequate doses of opioids for painpatients, since such patients are not at risk of becoming “addicted.”
Now a study from the University of Glasgow confirms what painspecialists intuitively know: Pain patients do not become psychologicallydependent on drugs because they are taking narcotics to relievetheir pain and for no other reason; drug abusers, on the otherhand, use narcotics strictly for mood alteration or to inducesleep.
The researchers surveyed three groups who were receiving narcotics:cancer pain patients , patients with chronic nonmalignantpain , and drug addicts enrolled in a methadone maintenanceprogram .
The cancer pain patients had been using opioids for a mean of6 months; the chronic pain patients for 2.2 years; and the drugabusers for 13 years. Median daily morphine equivalent doses weremuch higher in the cancer patients than in the chronicpain patients or the drug abusers .
The results showed that pain patients are not psychologicallydependent on strong opioids. “They have a need to use themfor pain, and when that pain isn’t there, they basically don’tneed them,” Dr. Fallon said.
Opioid Tolerance Dependence And Withdrawal
From a clinical standpoint, opioid withdrawal is one of the most powerful factors driving opioid dependence and addictive behaviors. Treatment of the patients withdrawal symptoms is based on understanding how withdrawal is related to the brains adjustment to opioids.
Repeated exposure to escalating dosages of opioids alters the brain so that it functions more or less normally when the drugs are present and abnormally when they are not. Two clinically important results of this alteration are opioid tolerance and drug dependence . Withdrawal symptoms occur only in patients who have developed tolerance.
Opioid tolerance occurs because the brain cells that have opioid receptors on them gradually become less responsive to the opioid stimulation. For example, more opioid is needed to stimulate the VTA brain cells of the mesolimbic reward system to release the same amount of DA in the NAc. Therefore, more opioid is needed to produce pleasure comparable to that provided in previous drug-taking episodes.
The Neurobiological Basis of Dependence and Withdrawal
The locus ceruleus is an area of the brain that is critically involved in the production of opioid dependence and withdrawal. The diagrams show how opioid drugs affect processes in the LC that control the release of noradrenaline , a brain chemical that stimulates wakefulness, muscle tone, and respiration, among other functions.

Common Questions About Morphine
Morphine is from a group of medicines called opiates, or narcotics.
It works in the central nervous system and the brain to block pain signals to the rest of the body. It also reduces the anxiety and stress caused by pain.
When morphine blocks the pain, there are other unwanted effects, for example, slow or shallow breathing. It also slows down digestion, which is why morphine can cause constipation.
This depends on the type of morphine you take.
A morphine injection into a vein gives the quickest pain relief. It works almost straight away.
Fast-acting morphine taken by mouth works in 30 to 60 minutes but it wears off after 4 to 6 hours. Slow-acting morphine taken by mouth can take a day or 2 to start working but the pain relief will last for longer.
It’s difficult to say how long morphine suppositories take to work, as it varies from person to person.
Yes, morphine is addictive. If you need to take it for a long time your body can become tolerant to it. That means you need higher doses to control your pain.
But in reality, if you’re taking morphine to relieve pain it’s very unlikely you will get addicted to it because you’re not taking it to get a “high”.
If you’re addicted to morphine, you may find it difficult to stop taking it or feel you need to take it more often than necessary.
Talk to your doctor if you’re worried about addiction or if you want to know more about how to prevent withdrawal symptoms.
Factors Influencing Withdrawal And Detox
Detox in general lasts 5-7 days. Withdrawal severity and duration can be influenced by many contributing factors, such as:
- Amount and duration of drug use: The longer and more morphine someone uses on a regular basis, the more likely the person is to be more heavily dependent on the drug.
- Biological or genetic influences: Personal or family history of addiction and other biological factors can contribute to a persons level of drug dependence.
- Co-occurring disorders: Underlying medical or mental health conditions may impact drug dependence, treatment, and withdrawal.
- Polydrug abuse: Abusing more than one drug, or alcohol, with morphine can increase the odds for developing a more significant dependence more rapidly and will need to be addressed during detox.
- Environmental factors: Stress, peer pressure, and a persons external environment can also contribute to drug abuse and dependence.

Naloxone And Opioid Overdoses
Fentanyl overdoses have so much media attention that many people forget that there are many other types of opioids out there. Morphine is also one of the most dangerous opioids on the market that can cause an overdose.
Fortunately, there is now a âcureâ or an âantidoteâ that can reverse the effects of the opioid overdose. This âantidoteâ is known as naloxone. This miracle drug is one of the many ways that the government is using to fight the rising opioid epidemic in America.
What Are The Risks Of Morphine Addiction
Over 155 Americans die each day from opioid addiction, which includes prescribed painkillers such as Morphine, as well as illicit substances like heroin. Morphine is a Schedule II narcotic under the Controlled Substances Act, which means it has the highest potential of abuse for a drug that can still be legally used for medical treatment. Those who misuse the drug also experience effects similar to that of heroin because the Schedule I semi-synthetic drug is derived from morphine.
Morphine abuse can lead to an overdose occurring, which may result in a coma, or death if left untreated.
Here are the signs of a morphine overdose:
- Respiratory depression
- Constricted pupils
The most serious psychological side effects of morphine addiction is depression. Prolonged morphine abuse causes a feeling of euphoria while preventing your body from being able to create a sense of well-being without the drug. The lack of natural well-being causes the user to feel depressed whenever they are off the drug, making it difficult to stop using.
