No Set Amount But...: There is some evidence that smoking can "stunt" growth by causing bone growth centers to fuse (and therefore stop growing) earlier than normal. But I do not know of any evidence which correlates the amount of smoking required to stop growth. At 22 years of age, you have undergone the vast majority of skeletal growth.

I don't know.: The natural history of nicotine dependence in teens study (funded by the canadian cancer society) published in the journal annals of epidemiology (17 march 2008) showed that on average, teenage boys who smoked were 2.54 cm shorter than their non-smoking counterparts. I have not reviewed this study – so i can not comment on the quality of the research.
