hi I was wondering first of all if second smoke while a teenager can stunt growth. I am 5'11, a pretty good height, but on my mom's side my uncles are taller (although my mom herself is not that tall at all), my grandfather is tall, and in their ancestors, they are known to be tall. I never smoked in high school, but in grade 12 I hung around with my friends who did smoke, could it have affected my growing capabilitiesb
