A study of 69 compulsive gamblers published in the American Journal of Psychiatry revealed the following results:
62 percent of the gamblers in the study suffered from a co-occurring psychiatric disorder
42 percent met the diagnostic criteria for a personality disorder
33 percent met the criteria for alcohol abuse or dependence
Study participants with dual diagnoses suffered more negative consequences as a result of their gambling than those who did not have a co-occurring mental illness or substance use disorder
Plus, the guy just looked like an alcoholic/addict. I can spot them a mile away.
