LANSING (AP) — The state of Michigan has created rules so there are testing standards for the first crop of industrial hemp.

The state launched a pilot program this year allowing for the growing and processing of hemp. The state’s Department of Agriculture and Rural Development on Thursday announced emergency rules that establish sampling and analytical testing methods for measuring the concentration of tetrahydrocannabinol in the emerging crop.

Hemp contains ultra-low levels of the THC that creates a high in marijuana. The rules will be in place for six months and can be extended for an additional six months.
