How do you help a steroid abuser who does not want to quit or even acknowledge that there is a problem?

*show what will happen (negative side effects)
*explain deeply about steroid and tell them that it is very harmful for the body
*change their mind by telling them to quit
*tell them that their life will shorten
*explain to them the other ways to build body such as exercising and having a good diet
*tell them that they can build a good shaped body without using steroids
