It was perhaps the starkest display yet of legal pot states' uncertainty on how to regulate the drug under President Donald Trump. Alaska marijuana regulators recently delayed planned rules for on-site pot consumption at dispensaries.
Colorado's measure, which would have allowed users to bring their own pot to clubs, initially had substantial bipartisan support. But lawmakers ultimately sided with Gov. John Hickenlooper, who has warned that bold changes may anger federal drug enforcers.
"Given the uncertainty in Washington, this is not the time to be ... trying to carve off new turf and expand markets and make dramatic statements about marijuana," Hickenlooper told The Denver Post last month.
