For years "snowbirds" has been a nickname given to out of state tourists flocking to the mountains every winter.
After January first there might be a new nickname..."smokebirds."
"Yeah, we follow the smoke," Robert Cox said.
Cox and his wife, Miranda, just got married in Texas and decided to spend their honeymoon in Colorado getting high.
"It's like a corner store with weed! Where we're from it's like a back alley deal," Cox said.
David Peebler, from New Jersey, is on a cross-country RV trip with his family.
"We timed it so we could be in Colorado for this momentous occassion," Peebler said.
According to Marisol Therapeutics owner Mike Stetler, 3 out of every 4 customers so far have been from out of state.
"They come for a quarter or an eighth. They travel all this way just to get that receipt to make history," Stetler said.
Each person we talked to from out of state said they think it's just a matter of time before the laws change across the country.
"It's like this, once toothpaste is out of the tube, you can't stick it back in. It's just a matter of time," Peebler said.
