When a gambler gambles under the influence of alcohol or drugs, it has the ability to affect their decision making. Drugs, alcohol or substance use in gambling can make a gambler over gamble, go over their budget, chase a loss, and be totally numb to feeling the effect of losing.
In casinos where free alcohol are served to customers who are gambling, the gamblers will most likely gamble more even without knowing.
