Casey Hardison

Casey Hardison, an infamous DIY chemist and longtime advocate of psychedelic drugs, was arrested in Yorkville, California, last week, two years after he led cops on a high-speed chase through Jackson following a botched drug bust.

Hardison is wanted on a $500,000 arrest warrant in Teton County on charges of delivery of marijuana and aggravated assault and battery. He’s in the Mendocino County, California, Jail awaiting extradition back to Wyoming.

Deputies there encountered Hardison on July 28 after a welfare check came in for a woman, Mendocino County sheriff’s Lt. Quincy Cromer said.

“It was a concerned sister,” Cromer said. “She got a call from her sister, who was involved with Mr. Hardison. She was worried about her.”

Deputies went to Hardison’s house on Elkhorn Road in Yorkville and found Hardison and the woman.

“They checked on her, and she needed medical attention,” Cromer said.

An ambulance responded to take the woman to a hospital. Her name and the reason she needed medical care were not available.

Hardison wasn’t charged with any crimes related to the woman.

He was arrested based on his felony warrant in Teton County and a misdemeanor warrant he has in San Francisco for failure to appear on a misdemeanor count of false imprisonment.

The Teton County Sheriff’s Office has until the end of August to work out transportation logistics to get Hardison back to face pending charges, which stem from an Aug. 6, 2018, incident in Jackson.

According to court documents, agents with the Wyoming Division of Criminal Investigations tried to arrest Hardison in an undercover drug sting.

But the interaction left Hardison with $6,000 of government cash and the cops with 2 pounds of marijuana.

Police said Hardison almost ran them over when he realized he was about to be arrested, hence the aggravated assault charges.

Hardison told the News&Guide that he took off quickly because he thought he was about to be robbed.

“They were in unmarked cars and plain clothes,” Hardison previously told the News&Guide.

“They displayed no insignia and were wearing none,” he said. “At that point in time, I had the right to protect my safety.”

Police chased Hardison through Jackson but eventually stopped for safety reasons, they said.

Hardison, 49, is known for challenging U.S. drug laws and spending time in prison for running a European LSD lab. In various online articles he’s referred to as a semifamous drug wizard and chemist.

He waived extradition in California, meaning he isn’t challenging his return to Wyoming.
