This is the example I'm shocked more people don't invoke in these discussions. Gambling addiction is indisputably real, and slot machines (or craps tables or the ponies down at the track) don't even have stick a needle in you to get you hooked. Actions and reactions are more than enough.
Compulsive overeating relies on the same behavioral/reward mechanisms, with the added bonus of food being something you do physically ingest in the process.
