You Have Been Summoned to an Apartment Complex for an Unknown

You have been summoned to an apartment complex for an unknown medical call. On scene, the police meet you and inform you that they have a 24-year-old male who smoked some "bath salts" and is acting erratically. As an EMT, you recognize that bath salts are:

A) drugs that depress the central nervous system.
B) drugs that increase circulating norepineprhine.
C) drugs made synthetically from bath and shower cleaners.
D) drugs that sedate and slow the respiratory drive when taken in excess.
