Your brain is the most powerful part of your body. That's one thing I think you agree. In both cases you can say no though. There isn't a question of people getting dependent/addicted to things. Are you saying the drug is more powerful than choice?
Again, I am not stating that people are not part of the problem. There are those that allow or embrace the addiction.
Now that we have that out of the way. There are those that have no control over the "addiction" because it becomes a physical and psychological dependency. These drugs work in many different ways. They alter the perceptions in the brain's receptors, they alter the signals sent by nerves throughout the body. These actions have adverse actions that, in many instances, create a psychological and physical dependency created by the patients brain, CNS, muscles, etc...
It is exactly why I live in pain every day myself. Addiction has been linked to genetics. The doctors would only do so much for my shoulder as they could not take any more bone out to try and fix my AC disorder which has contributed to numerous dislocations and tears along with secondary issues attributed to compensation now popping up. As I age, the insurance companies will allow more fixes to be attempted. For now, they want me on long term pain medication.
