Thanks you for the suggestions and for pointing to a more realistic point about addiction. As I see - and I've been living in this for many years - addiction has nothing to do with the chemical. Johann Hari has some very good thoughts on the topic. The first time I heard about him was this talk: https://www.ted.com/talks/johann_hari_everything_you_think_y...

His books worth checking out too. As someone who struggled with addiction since childhood it is something I can very much relate to.
