			 The complaints, one aimed at state government officials and the 
			other at marijuana businesses, were filed in U.S. District Court in 
			Denver by a hotel operator and the owners of a Colorado horse ranch. 
			 
			Colorado is among four states where voters have approved the 
			possession and sale of marijuana for recreational purposes, although 
			pot is illegal for any purpose under federal law. 
			 
			President Barack Obama's administration has allowed states that 
			permit medicinal or recreational marijuana leeway in regulating its 
			use. 
			 
			In a news conference to announce the lawsuits, the plaintiffs' 
			lawyer, David Thompson, accused Obama of turning a blind eye to the 
			enforcement of federal drug laws, saying: "In this country, only 
			Congress can change federal law, not the president." 
			 
			Thompson, a lawyer with Safe Streets Alliance, a Washington-based 
			organization aimed at reducing youth drug use and violence, said 
			Colorado's regulatory scheme amounted to an illegal drug conspiracy 
			and as such was "a quintessential racketeering enterprise." 
			  
			The hotel operator's lawsuit said: "Marijuana businesses make bad 
			neighbors. They drive away legitimate businesses customers, emit 
			pungent, foul odors, attract undesirable visitors, increase criminal 
			activity, increase traffic, and reduce property values." 
			 
			Another plaintiff, Hope Reilly, told reporters she planned to open 
			an animal-assisted therapy program for children on the 105-acre 
			horse property she owns in the south of the state. 
			 
			"Having a recreational marijuana cultivation facility next door 
			interferes with that," she said. 
			 
			In December, Colorado's marijuana laws were challenged in the U.S. 
			Supreme Court by the neighboring states of Nebraska and Oklahoma, 
			which say marijuana sold in Colorado has been smuggled across state 
			lines.

			The Colorado Attorney General's Office has vowed to defend against 
			that lawsuit, and a spokeswoman for the office said on Thursday the 
			agency would likewise fight the latest legal action in order to 
			uphold state law. 
			 
			The owners of the marijuana businesses named as defendants in the 
			lawsuit could not immediately be reached for comment, but supporters 
			of the industry spoke in favor of the state's regulatory efforts. 
			 
			Democratic State Representative Jonathan Singer said Colorado had 
			reaped millions in taxes and fees for much-needed programs since 
			recreational cannabis became legal. 
			 
			"The sky hasn't fallen," Singer said. "We have to stop rehashing the 
			fights of old."
