Should I throw their addictive substance away?

My bf has admitted his addiction to me and has been trying to quit for a few months now because of the stress it puts on our relationship. He wants to quit really badly, but frequently relapses. I thought maybe if I removed temptations from the home, it would help him. But I’ve heard mixed advice on this from friends and family. What do you think reddit? Should I just throw everything away?

(Yes I’m purposefully being vague about his addiction because there’s a wholeeeee story about it and didn’t want to write a super long post.)
