In some states bestiality is legal, does that mean it is ok to forget your dog?
No.. but the reason it's not okay to forget your dog isn't because it's illegal.
On another note people don't realize they are addicted to stuff most of the time, my parents think I am addicted to video games and majority of people here probably think I am addicted to ponies but I think neither are right.
Did you really just say that?
Except drugs mess with your brain causing it to be an addiction so your comparison is flawed.
Other things cause a lot of the same actions as drugs do. Winning a boss battle in a game causes a surge of dopamine similar to railing off a line of cocaine.
