How to make an exception in Erlang?

I'm new to Erlang, and I found how to handle exceptions in the User Guide, but not how to throw them. Is it possible to identify and then throw my own exception?

this is from raising erlang exceptions

An example of creating an Erlang exception with an exit (why).

-module(exceptions).

-export([sample_error/0]).

sample_error() -> throw("some bad happened").

Now let's compile our exception module, call the sample_error () function and observe> the output of the raised exception.

erlc –o ebin src/exceptions.erl
erl –pa ebin

1> exceptions:sample_error().
** exception throw: "some bad happened"
  in function  exceptions:sample_error/0
