Here is the fact, we have many addicted celebrities on earth who are rich, wealthy in a fact, and they can't escape relapse either. Maybe addiction treatments must concentrate on the history of one's addiction as much as the present of the addiction.
Here is a list of famous celebrity addicts. Here is how this web site makes its statement about this, which I think is true:
Drug and alcohol addiction knows no boundaries when it comes to social classes, wealth, ethnicity or status. Addiction is a part of every group of people everywhere.
This list of famous and celebrity addicts is by no means comprehensive. Sometimes it is helpful that people who are struggling with addiction know some famous names that have struggled or are struggling with the same issues. It helps one to not feel so alone in the process.
