Kiddo, stop now. Recreational smoking is loads of fun until you get addicted. I know you think you’re stronger than that and you’re the exception to the rule, but sometimes part of being a teenager is learning that you’re not smarter than everyone older than you.
I started when I was 14 and wasn’t addicted for about 2 years. Thought I was beating the system. Turns out, the system was built to win.
Stop smoking, start running. Really.
