Oklahoma City — A Tulsa medical marijuana grower is suing the state over what it calls excessive fees and taxes.

Caulfield Holdings Botanicals, a Tulsa company that intends to grow marijuana for the medical market, and Alicia Vargas, a medical marijuana patient from Weatherford, filed a lawsuit on Friday and will ask an Oklahoma County district judge to make it a class-action case.

In the suit, they argue the Oklahoma State Department of Health overstepped its bounds when it required growers to register with the Oklahoma Bureau of Narcotics and Dangerous Drugs Control.

A narcotics license for a grower costs $500, on top of the $2,500 that cannabis businesses must pay to the Oklahoma Medical Marijuana Authority.
