Colorado Gov. John Hickenlooper on Tuesday cautioned other states about the economic impacts of legalizing marijuana.

At a conference in Dallas on public-private partnerships — like the U.S 36 expansion and toll lanes — Hickenlooper was showing a slide that said the U.S. would have 22 million more millennials than baby boomers in the year 2030, when he said:

“You get all those young people who do certain things that some of us oppose and aren’t crazy about, like legalizing marijuana. Let me tell you, if you’re trying to encourage businesses to move to your state, some of the larger businesses, think twice about legalizing marijuana.”

Denver7 followed up with his office to see which businesses spurned Colorado because of legal marijuana.

“The governor knows marijuana is part of the conversation in recruiting companies to Colorado, but it has not had any measurable impact to the economy,” his office wrote in response.

At his State of the State address in January, Hickenlooper made reference to booming economic development in Colorado.
