Morphine is addictive and can be habit-forming.

In fact, you can become dependent on the drug both, psychologically and physically. Morphine addiction is very cruel, as the drug causes strong cravings, strong enough to drive addicts to commit acts they would never otherwise commit. Withdrawal from morphine can cause a number of issues, too depending on the dosage taken and how long it was used.

So, what does morphine use and addiction look like? We explore here. Then, we invite your questions or comments at the end.

Morphine’s mechanism of action

Morphine binds to opioid receptors… more specifically to

1) The Mu-receptors, which are present in the brainstem and the thalamus. The activation of these receptors can result in pain relief, sedation and euphoria as well as respiratory depression, constipation and physical dependence.

2) Kappa receptors, found in the limbic system, a part of the forebrain called the diencephalon, the brain stem and spinal cord. When activated it’s responsible for pain relief, sedation, loss of breath and dependence.

3) Delta receptors present in the brain and also present in the spinal cord and digestive tract. Stimulation of this receptor leads to analgesic as well as antidepressant effects.

How addictive is morphine?

  1. I was born with a tethered spinal cord. I began having pain when I was 16 in 1980, it was at first easy to control with a Tylenol or aspirin but, by the time I was 20 I was on and off opiate pain killers, sometimes going months without them but eventually needing them more and more. I am 53 now I had surgery in 2004 when I finally found a doctor at Georgetown University Hospital found the problem plus two benign tumors located in the filume. After surgery I did all recommend rehab and was very positive and staying far away from any negative thoughts and PEOPLE but, the pain never left they did nerve studies and found that the calcifications around all the nerve roots had done irrecoverable damage even after they did all they could to remove it from around the nerve root. I am what they call dead end they can’t do anything thing else to help me so basically they don’t even look each month I go pee in the bottle spend 5 minutes telling how my month was then get handed two scripts and out the door till next month. I’m tired I’m so very tired and depressed to know each and everyday of my life from now till I die is going to be just like this. I have been disappointed so many times with different procedures and medication changes and what it’s done to my body that I believe allot of people would have just given up. I want help and need it and I will not give up.

  2. I was addict to morphine from 1999-2005, I received help through MMT until 2010, I relapsed onto methamphetamine for weight loss, then back to morphine. I again went onto MMT from 10-2013 until March,2015 where I began Suboxone and SAIOPT. I go to 1 or 2 twelve step meetings a day, work the 12 steps with a sponsor and my life has become a place that I love! Recovery is a daily process and I am a work in progress! The gates of Heaven didn’t open up and let me in but the gates of Hell opened up and let me out!!!!!!!!
