When I think of "vice," I think of something I take pleasure in which really isn't good for me. I guess smoking cigarettes is my worst vice. I probably drink a little too much alcohol too. I overspend money a bit on energy drinks when I really should just be buying those Mio water enhancers with caffeine in them, but I'm probably going to end up doing that soon enough. I do drugs now and then. But they don't adversely affect my life, so I don't consider my drug use a vice.
