What you are saying ia only half true. While you can get addicted to let's say your phone, it's still natural. You can put it down and pick it up any time, you just have a harder time reasoning with yourself, and will do it sometimes out of habbit.

However drugs manipulate your brain, and getting addicted to drugs is on another level of addiction. The "harder to reason with yourself" part becomes near impossible. Without help you borderline can't stop.

With a "natural" addiction your impulses are still in a healthy range. You are in control, it just guides you to something that you like subconsciously.

I oversimplified and I'm also not a professional at this topic, but I did some research. I was curious about why can't ppl stop playing some videogames, while others are just an activity, nothing more. (Also why the tiktok formula is so addicting)
