DNA does not make anyone an alcoholic or drug user. There are markers that show a greater propensity toward rewards from such behavior, but a huge number of people never have issues, despite these markers.
A person who eats too much gets fat. That is also not a disease, yet larger people say they can’t stop it. Fat cells, after dieting, release more hormones to encourage eating to regain weight. Still, this “genetic” behavior does not make eating too much a “disease.”
Alcoholism is simply a matter of self-control, just as eating too much is, too.
You are so uninformed
Keep on keeping on though. Because ignorance is boiss
