Mark Ryan says at least 84 people around Louisiana have been hospitalized due to paranoia, hallucinations, suicidal thoughts and/or other effects of the drugs.
The Louisiana Poison Center received 91 calls about the drug, while the rest of the U.S. Poison Centers have only received a total of 69 calls.
The drugs are mephedrone (MEF-uh-drone) and MDPV, short for methylendioxypyrovalerone (METH-uh-leen-dy-OX-y-PYro-VAL-uh-rone).
Both drugs keep the brain circulating chemicals called dopamine and norepinephrine, the same chemicals affected by Ritalin and many other prescription drugs.
