Addiction is this really scary thing I saw on tv about downtown Philadelphia and fentanyl killing people buy that's far away and couldn't happen here. Sure, I have friends who are fat and are unable to stop themselves from drinking 8 cans of coke a day but they're not shooting up with needles and I know them so they can't be this scary kind of person called an addict. Also I know this one girl who's glued to her phone all day and can't do anything else and she's also definitely not an addict.
Addiction hits the same part of the brain, no matter if it's chemical, physical, or digital. Just because our culture sees them differently doesn't make it the same underlying problem.
