Addiction develops over time and usually starts with misuse, moving toward abuse and leading to addiction.
To minimize emotional or physical distress, someone might experiment with drugs or alcohol. One may use drugs or alcohol to be comfortable in a social setting, and decide to take the substance again simply to have fun. Relieved of emotions of unpleasantness, the person will continue to use substances or alcohol again, and again, and so on.
Before long the person boosts use to sustain the longed for effects of euphoria and escape from reality. The problems of origin remain unattended and/or unresolved. Problems will be created because of the usage if the person didn't have issues at the beginning of usage. Continuous efforts to gratify the physical body's cravings for the substance or alcohol emerge as the person's new reality.
Tremendous time and effort is spent acquiring the alcohol or substances. Once the addict or alcoholic is totally entrenched in the cycle of addiction, the health, economic, emotional and social penalties show up. The addict may simply feel that they have been unlucky, or blame the penalties on other people as opposed to their addiction.
