Legend
Just wanted to acknowledge you sharing thatI have never played with anyone who had a substance abuse problem. I have played with people who have mental health issues such as depression, bi polar and PTSD.
I have all three of those diagnosis so I deal with mental illness everyday of my life. I have found that people with mental health issues are attracted to things like gaming because it allows you to play being someone else.
Though I have never played with anyone who made it impossible because of their issues to have them at the table.
I have also played with a great many well adjusted people.
Because of the nature of gaming I think you are more likely to see the illness manifest itself than if you were just going to the movies.

I think of gaming as a form of creative expression, and artistic highly intelligent people tend to suffer some degree of madness. Robin Williams used to play D&D and suffers bipolar disorder...
