Is it possible that smoking hookah daily for 2 years between ages 16-18 have stunted my growth? i feel underdeveloped and was a late bloomer.

No it is not: No smoking hookah will not cause stunted growth.

Possibly: A Université de Montréal study of 1,293 teens over a 5 yr period, funded by Canadian Cancer Society indicated “a boy who smokes 10 cigarettes a day from age 12 to 17 will be about an inch shorter than a boy who does not smoke at all.” https://www.sciencedaily.com/releases/2008/03/080331135155.htm. I was unable to find the actual study to review it. I haven’t seen this reported elsewhere.
