What Is Chemical Addiction
Accepting that we're dependent on drugs or alcohol is hard. We find we do not fit our idea of an addict or alcoholic. Old family values, cultural beliefs, movies and television shows have given us inaccurate pictures of alcoholics and addicts. These images have influenced our thinking. We may see people who are chemically dependent as losers or failures or as people in the gutter of life which is certainly not the way we want people to see us.
The terms addiction, addict and alcoholic carry a stigma or feeling of shame. Many people believe that addiction is a weakness (if we were just morally or emotionally stronger, we could "lick" this problem), we should be able to stop using on our own and we just do not have enough willpower (if we were more disciplined we'd be able to stop).
The only thing I can tell you is do not buy into these myths. People who've never encountered the true nature of addiction can't conceive of what an addict is going through. They have never experienced the inability to stop chemical use. They just do not understand. The responses of our loved ones and close friends can be particularly hurtful.
We may see the addiction as unfair. No one ever said "Hey you, stand in this line if you'd like to become addicted to alcohol or drugs and ruin your life". Dependency is seen as a curse in which there are no answers. But there is an answer. It is called understanding the addiction process.
Addiction to alcohol/drugs is a complex illness. It is progressive and can be life threatening. It has social, physiological and psychological components.
The process of addiction begins with drug availability to the purity and route of administration. Dose, frequency and duration of use, genetic factors, developmental factors, mental illness, chronic pain and psychosocial factors all influence the process of addiction.
Then there is the brain chemistry of addiction. When mood altering drugs are put into one's body the bloodstream picks up these chemicals and quickly carries them to the brain. Inside the brain, these chemicals set off the complex chemical reactions within the brain and distorts the reality. This altered state is commonly known as "intoxication". Some people find this feeling pleasant. Others find this experience unpleasant.
Addiction is not about willpower or weakness. Research has shown that the addiction process is connected to how the brain is wired. Powerful chemicals called neurotransmitters control brain activity. They carry messages from one brain neuron to another. Whereas the cerebrum is the thinking part of the brain, "I will never use drugs or drink again". It is the brain stem that is home to the limbic system that contains the components of addictive behavior.
The limbic system stimulates the sense of smell, motivation, sex drive and complex emotional responses. It also contains what is called the "pleasure center".
The pleasure center responds to what else, pleasurable stimulation and learns to repeat it. Neurotransmitters endorphins and dopamine activate the pleasure center. Alcohol and drugs increase the activity of these neurotransmitters resulting in feelings of euphoria. The cycle begins with that first drink or that first pill.
Over time, the body stops making these neurotransmitters on their own because they have become accustomed to the presence of alcohol/drugs. Without the alcohol/drugs , the let-down begins as the brain is awaiting more alcohol/drugs. When the body is out of balance, the cravings begin. The need for the use of alcohol/drugs becomes intense and eventually takes over. The "thinking part" of the brain screams "stop". The "limbic part" of the brain screams "go".
