Counties in the U.S. state of California continue to put up roadblocks for hemp growing. Both Contra Costa and Tehema counties recently halted new grows. Smells coming from the plantations and hemp’s similarity to marijuana were cited in the stoppages. Contra Costa County’s Board of Supervisors approved a 45-day moratorium, saying current regulations are under review. The board said the moratorium could be extended for as long as another year. Tehama County Board of Supervisors this week extended a current moratorium to March 1, 2021, also to give county officials time to sort out local regulations.
