not enough information. even though you are 16 i don't know if you are male or female or if you have completed your natural growth. a person cannot grow after their growth plates have closed and it would take an x-ray to make that determination. also i don't know your genetics. tall parents tend to have taller kids etc. and some kids do grow taller after 16. some do not. finally i don't think anyone should smoke anything. not good for the lungs and the overall health. whether smoking will "stunt your growth" is really not the issue. smoking is just bad. period. you don't need to smoke on a hookah no matter what your friends are doing.
okay so i am 16 and i want to grow about 3 more inches if i smoke hookah once or twice will i grow to my goal height!
