Bloomington Mayor Tari Renner said the city is unlikely to opt out of legalization. Normal Mayor Chris Koos said it's too soon to tell if or how the town would address opting out.

Barickman said he won't vote for any proposal that doesn't allow employers to choose whether or not they can hire or continue to employ people who test positive for marijuana use. He'd also like to include taking away driver's licenses from those who use marijuana before they're 21 years old.

He noted working people and youths are not the demographics that have changed behavior most in the states with legal recreational marijuana.

"It's those who are empty nesters, who may or may not have used cannabis when they were younger, in college. They're rule followers. They don't use today because it's against the law. But they may change their habit. You don't have to raise your hand," said Barickman with a laugh.

Barickman said legalization is not only potentially lucrative but also would end an expensive and failing effort to prohibit marijuana use.
