BG Daily News reports the Senator as saying,

“Originally what inspired me was a group of retired Teamsters,” Clark said. The Teamsters knew that using marijuana was a cheaper alternative to costly prescription painkillers they needed, he said. “They didn’t want to be criminalized for something that shouldn’t have been criminalized in the first place,” he said.

Clark’s bill is heavily based on Colorado Amendment 64, which legalized cannabis there in 2012, he said. The proposal was put on a statewide ballot by popular initiative and was approved by 55.32 percent of the total vote. During the 2014-15 fiscal year, the state raised $100 million in taxes on adult recreational marijuana sales. In addition, marijuana arrests and citations have gone down roughly 80 percent and the state’s tourism has increased by 10 percent, Clark said.
