If you have a layover in Denver, 420 Airport Pickup will take you to a marijuana dispensary, a place to get high and on a scenic tour before dropping you back off at Denver International Airport.
Or there's the art studio where you can smoke pot while painting with acrylics; Kush and Canvases also offers a class on rolling sushi – and joints. On a Budz and Sudz tour, you can visit both craft breweries and a marijuana growing operation in Denver, riding a tour bus stocked with snacks.
Or to get stoned while riding in a limo or party bus, Colorado Cannabis Tours offers "high-end hot boxes on wheels" with "complementary bongs & beverages" – and don't worry, the driver's cabin is walled off with its own air source and filtration.
Since Michigan voters on Tuesday approved a proposal to legalize marijuana, these kinds of attractions could be coming to that state in the next few years. And big cities, such as Chicago and Cleveland – both within a couple hours of the border – don't have legal recreational pot and are likely to have some cannabis-hungry residents.

David Lorenz, vice president of Travel Michigan, said Michigan is already the 11th-largest state for leisure travel. But he said that while legal pot may bring a short-term increase in tourism, he's not expecting it to be as dramatic as some might expect. More: 10 best 4/20 sites: Where marijuana history was made

"I'm thinking there will be a select audience who will travel, they want to consume marijuana legally so much that they will travel for that. But I think this is going to be, like, amid the other attractions," he said. "It's something that you may do while you’re here, but it may not be your main motivation for traveling here."
He pointed out that Canada recently legalized marijuana, offering an alternative for people in the Midwest. And as the 10th state to legalize recreational marijuana, Michigan comes after other travel destinations, such as Las Vegas, the West Coast and Vermont.
"There is more competition," he said. "There are other places to go now."
While craft breweries have become a popular draw in Michigan, and people go winery-hopping in the northern part of the state, Lorenz said he doesn't anticipate such "atmospheric experiences" becoming normalized for marijuana experiences.
"I'm just guessing because we haven't gone through it yet," Lorenz said. "I wish I could sound a little more excited. I always am reluctant to get over-excited about (new) markets of any kind."
On Nov. 1, Planet 13 opened in Las Vegas. Appropriately for the flashy city, it offers "light shows and fog-making fountains to wow visitors at the shop, which sells recreational pot, cannabis extracts and cannabis-infused products," the Los Angeles Times reported.
Visitors over 21 can change the colors of 13 massive LED-lit lotus flowers on the roof, each of which is 15 feet tall.
"Inside the store, there’s more than 16,500 square feet of retail space devoted to cannabis products – amid motion-activated floors, a 3D projection wall and colorful orbs floating above cannabis display cases," according to the Times.
Whether Michigan develops anything nearly as zany, such developments are at least not likely until 2020, as the ballot language allows a year for the state to approve rules and regulations before the industry starts to bud.
