The Science of Opioid Addiction
Addiction is a powerful physiological process ... not a weakness of character or lack of discipline. Doctors, lawyers, judges, pastors, star athletes, CEO's, and heads of state have all experienced the gripping reality of a personal opioid addiction.
Opioid dependency is classified as a true medical condition and is the direct result of dramatic brain structure changes. Once these brain structure changes take hold, an individual is no longer left with an easy choice to "simply not use", but is faced with an overpowering & persistent compulsion to feed an opioid drug hunger. No one wants to become addicted. Remember, the person did not want this to happen.
This overpowering urge is a phenomenon that most non-addicted people have difficulty understanding. People often naively ask "Why can't they just stop?" If it were that easy, they would! For an opioid dependent individual, the overpowering urge to use is very similar to a typical person experiencing extreme hunger after not eating for a prolonged period of time. The longer one goes without food, the more intense becomes their physical discomfort, and the hungry person becomes sharply focused on finding something to eat. This is a powerful physiological drive that blocks out other goals & considerations ... until the need is met.
Another illustration is a person severely dehydrated and overcome with the desire to take in fluids. When they get to water, they rapidly gulp it down trying to satisfy their extreme thirst. Yet another example is the powerful sleep mechanism which kicks in after many hours wide awake. If you have ever watched someone fight sleep, you will inevitably see them give in to sleep as the body's physiological need overcomes the individual's intention to remain awake. And such is the case with a physiological dependency on opioids. The drive to use becomes increasingly powerful and eventually overwhelms the addicted individual.
Due to structural changes within the brain, the brain begins to crave opiates like people crave food, water, and sleep. And just as someone becomes intensely symptomatic when deprived of food, water, or sleep, the opioid dependent person becomes increasingly sick from opioid withdrawal, and desperate to end their physical discomfort.
