Chronic alcohol use alters brain function and weakens willpower, rendering self-control extremely difficult when exposed to triggers.

Original passage

The man who has formed the habit of using intoxicants is in a desperate situation. His brain is diseased, his will power is weakened. So far as any power in himself is concerned, his appetite is uncontrollable. He cannot be reasoned with or persuaded to deny himself. Drawn into the dens of vice, one who has resolved to quit drink is led to seize the glass again, and with the first taste of the intoxicant every good resolution is overpowered, every vestige of will destroyed. One taste of the maddening draft, and all thought of its results has vanished. The heartbroken wife is forgotten. The debauched father no longer cares that his children are hungry and naked. By legalizing the traffic, the law gives its sanction to this downfall of the soul and refuses to stop the trade that fills the world with evil.
