If I have an addiction, can I still be saved?

Yes. You can always receive salvation whether you are a good person or a mass murderer. The Bible says in Romans 5:8, "But God demonstrates his own love for us in this: While we were still sinners, Christ died for us."

This, after we are told in Romans 3:23, "For all have sinned and fall short of the glory of God."

There is nothing you need to do to receive salvation other than surrender your life to God, pray and ask Jesus to come live in your heart and to be the Lord of your life. If we had to clean up our lives before we could receive salvation then no one would ever get saved. Isaiah 64:6 tells us that in the eyes of God, "all our righteous acts are like filthy rags."

With God, salvation is a 'come as you are' invitation. Once you accept Jesus as your savior, only then will God begin to work in your life. If you allow the blood of Christ to cover over your sins and make Jesus the Lord of your life then He will do a work to change your heart. In time this change of heart will result in your being changed from the inside out if you honestly begin to seek to follow Jesus daily in developing a personal relationship with Him.

A dear friend's adopted son was a cold-blooded killer before he was saved, but now a prison evangelist.

I have several friends who were drug dealers and users when they prayed to receive salvation. Obviously they are now free of the drug culture in that one is now a pastor and the other is a praise and worship music leader. However, they did not need to clean up their act before asking Jesus to come into their heart. All they needed to do was ask Jesus to come into their heart and be the Lord of their lives. From there on Jesus began to lead them in a way that took care of the rest.
