How Do I Help?

so i was talking to a friend and we have been friends for 2 years now. But one thing he told me and my other friend today was that he uses weed and drink when his parents aren't home. So he said he has taken weed at his friends house and that he is involved in gangs. Me and my other friend just couldn't believe it and we do not really know what to do and we do not want to be straight up to him because he might take it the wrong way. I really care for my friend and i don't want him hurting himself with drugs and we are only around high school ages so i don't know what to do. How will i help my friend???
