The number of people I see that say "oh I just use it to relax" is quite high. It is a way to ignore what is in front of you and not have to deal with it. I understand the idea quite well.
What twists me on all of this is the blame shaming of people who say 'do not do that junk'. When they can clearly see the chaos these choices bring. Choices are made one at a time and little choices eventually turn into big nightmares or happy times. Not everyone ends up there. But many do. I know a decent number as well.
Then once lets say you get 'cleaned up'. You now have to re-learn how to cope with life. As the usage of whatever is how you used to do it. But that is no longer there. So it is quite an emotional roller coaster for everyone involved.
