How Can I Support a Friend Who's Gone Through Drug/Alcohol Rehabilitation?

If you are asking this question, it shows that you are a caring friend, and that is probably the most important way you can support your friend. There are lots of other ways that you can support him/her too. One is to help your friend avoid situations where there’s a possibility that he/she could relapse and go back to using. Go with your friend to places that are drug and alcohol free rather than to parties where there are likely to be drugs.
