Can laser pointers kill you?
I suppose a crate full of them could fall on your head ...
Or someone could shine one in your eyes when you were driving
...
But barring something like that, laser pointers do not have
enough power to harm skin. You shouldn't look directly at them (as
the sign on more than one research laser I've seen says, "Do not
stare directly into beam with remaining eye"), but you can shine it
at your hand for as long as you like.
