After an investigation that spanned close to five years, federal authorities have indicted a Louisiana veterinarian with treating horses with an illegal synthetic drug.

The Associated Press reports that veterinarian Kyle Hebert has been charged with injecting at least four horses with dermorphin, a powerful Class 1 painkiller.

Authorities charge that Hebert intentionally mislabeled syringes containing the drug, claiming instead that it was an “herb,” and telling trainers that it would help their horses run faster.

The charges brought against Hebert stem from an investigation that began in 2012, when the Louisiana State Racing Commission suspended several trainers after many of their horses tested positive for dermorphin (a.k.a ‘frog juice’).
