Abstract: The influence of the Poincaré Conjecture on the following problem of M. Cohen is examined.

Problem. Does there exist a four-dimensional $ h$-cobordism with nontrivial Whitehead torsion?

It is proved (assuming the Poincarè Conjecture) that none of the following groups may be the fundamental group of a $ 4$-dimensional $ h$-corbordism with nontrivial Whitehead torsion: generalized quaternion groups, cyclic groups $ {Z_8}$, $ {Z_{12}}$, the binary octahedral group, the binary tetrahedral group.
