I know people who constantly drink to much. This leads to alcoholism
So do I. It's horrible! It can damage the brain, heart, liver, pancreas, and immune system!
Unfortunate for the drinker, they often relapse.  I'm afraid they make bad choices and put other at risk, especially when they drive while drinking
I know. It's so addictive because it rewires the several distinct dopamine pathways in their brain. Every time they drink it's a reward.
I had a friend whose father was an alcoholic.  She spent most of her time at MY home, afraid and alone . Her father had no discipline
I wouldn't say no discipline; addiction is a disorder that leads to compulsive behaviors despite consequences.
