You're absolutely right.
We all had mothers. My mother is gone now, but I'll testify that she was probably one of the wisest of women. She never smoked, but we would talk about smoking, and obviously with a large family, there were some who smoked. She would say that people need their vices. I can't imagine being in a prison when you're stripped of all those things. I think you described perfectly what that is—a stress reliever—and we have no idea of the types of stress.
Do you think it's a human right for them to smoke in prison?
