Both my parents smoked and I just didn't get it. I'm really tight with money also, I was probably the only 6 year old that could save money so when I got older I couldn't believe how much tobacco cost. I think it is insane that people smoke, it is really bad for you and it is incredibly expensive.
I can see why vaping has taken off though, it is touted as safer than tobacco, is cheaper, and tastes like candy. Still incredibly bad for you but by vaping you're being a lot more considerate to those around you.
