I'd say my biggest vices are internet addiction, video games, and porn but the last 2 maybe an hour or two a day only when I am not busy. I can go weeks to months without.

I am 30 and am pretty much retired. Do people get addicted to drugs and alcohol because of the pressure of making money and surviving? Why wouldn't they just see that they are wasting money and just work and save or invest the money? Help me understand.
