Hello there. My son (15) years of age told me he smoked around 3-4 cigarrettes the other day, he said he did NOT inhale them. This was his second time ever smoking, and he never wants to do it again. And now he is very afraid that it will delay his growth and his puberty or it will stop him from growing. Is this true, after these 4 cigarrettes will he stop growing and will it damage his stage of puberty? Thank you.
