I think there can be Christian culture stuff which helps to cause addiction. I mean if parents are not really Christians and they have only tried to get their kids to copy-cat what the parents have been doing. And then the children discover that it does not work to keep them deeply satisfied. So, the children go elsewhere with peers to try to find satisfaction. And the ones they associate with also do not know how to love. God's love is not satisfying them.
And so, in trying to kick an addiction, they might include various ideas, instead of submitting to God and learning with Jesus >
"'Take My yoke upon you and learn from Me, for I am gentle and lowly in heart, and you will find rest for your souls.'" (Matthew 11:29)
Also, there are children who rebel against how their parents showed them the right way. So, they go where they get nowhere, trying to pick and choose what will get them out of their addiction. And they can get isolated with people who are telling them what they want to hear. They might stop the addiction, but deeply they are not being cured in their character the way God is able to cure our nature in His love with almighty power against the nasty nonsense which drives people to substance abuse.
Only God through Jesus is able to change our nature so that the dominating and tormenting feelings and drives and reacting of addiction can not get the better of us. And only God is able to form Jesus in us as our new inner Person (Galatians 4:19) so we can please God like Jesus does (1 Peter 3:4, 2 Corinthians 2:14-15) and love like Jesus does (Ephesians 5:2) . . . more and more with growth and correction (Hebrews 12:4-11) and each other's help and good example (1 Peter 3:4).
So, ideas and practices and theories are not what really do all we need and all which God is committed to doing in us.
"Trust in the LORD with all your heart,
. And lean not on your own understanding;
. In all your ways acknowledge Him,
. And He shall direct your paths."
