Puberty? I'm young im 14?

You are never too young to start puberty. You should probably not smoke though, I started smoking when I was 13 and it took me 6 months to quit and now I'm 16 and I haven't had one in eight months! It can really be bad to your health when you are older. Try eating healthier and start going to the gym too. During puberty you are more subjective to putting on weight and getting acne when you smoke, drink or eat junk.
