DENVER — California has suspended 394 marijuana business permits in a move that critics say will temporarily reduce the number of legal cannabis shops in the state.

Reporting from Sacramento — A state bill that would have allowed cities to prohibit home deliveries of marijuana has been sidelined for the year amid concerns that doing so would further hamper California’s lagging market for cannabis.

Cannabis may be legal in California, but the new rules of the road are so confusing that even former California Highway Patrol officers are struggling with them.

SACRAMENTO — California authorities have tripled the number of raids on unlicensed cannabis shops in the last year and seized $30 million in pot products, but legal industry leaders say enforcement is still inadequate to break the dominance of the black market in the state.
