I'm interested in how addiction is so much more likely in some people than others. For over 20 years I loved to drink all sorts of different things. Once I had kids and hit 40+ it was so unpleasant in the morning so I decided to massively reduce. In the UK drinking is so pervasive. I limited my intake to <=2 drinks per night and never had an issue and would only break that maybe once a year. Recently I decided to reduce it even more. I will have a pint of ale in a pub if I go, but hardly anything else. It really didn't feel that hard.

Again at uni I found lots of people smoked cigs and mj and so I did it too a little bit, but decided after a year or 2 to stop and I've never really done it since. My dad was the same.

I've had the same realisation with certain foods recently and coffee, massively cutting down on sugar, salt and coffee.

Probably my only addiction at the moment is too much scrolling on my phone.

I totally accept this is a huge issue for many people, but no real idea why...
