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?
Morphine is a potentially highly addictive substance. It can cause psychological dependence and physical dependence as well as tolerance. Morphine also produces euphoria and other positive effects, which compel users to continue. Users have reported feeling addicted to it after few uses. So, this is certainly no “recreational drug”.
