Am I the only person who doesn't drink or smoke?

I don’t drink alcohol or smoke pot but it seems that everyone around me does. I’m 19 years old and in college, so I guess this is normal, but I’m just wondering if tehre are any flutherites in other life situations who are also sober all around. To be clear, I don’t necessarily have a problem with pot or alcohol, so I hope everyone answers honestly and without malice.
