Alcohol Addiction Rehab

Is it necessary in the detoxification treatment of addiction to alcohol?
My best friend is an alcoholic. I accompanied him to a rehabilitation of alcohol on Wednesday because I finally convinced him to get some help. The doctor and the adviser said that he has to undergo a detoxification first. What is detoxification? Is it really necessary? My best friend is making me these questions and I do not know what to say.
Yes is very important. See, detoxification is the removal of all that excess alcohol in the body. It really is the first step toward recovery. Your friend has to cleanse your body and eliminate all the filth that caused his alcoholism. A clean body complements a clear mind. Detoxification will help your friend to be sober.
