Is the world ready for a pot-themed food truck?

It's been a banner year for advocates of cannabis use.

Minnesota recently became the 22nd state to legalize the use of medical marijuana, and at least five other states have legislation pending regarding the medicinal use of cannabis. Colorado and Washington state, meanwhile, legalized the recreational use of marijuana for adults starting on New Year's Day.

With about half of the U.S. now having laws in their states that legalize marijuana, cannabis culture is coming out of the shadows in force. The Denver Post has a popular marijuana column, The Cannabist, that features pot-related news stories as well as information on cooking with marijuana. And the Internet is bursting with websites and videos from people looking to share their favorite cannabis-infused recipes.

One group in Seattle is even trying to combine two national trends -- the marijuana culture and the highly profitable gourmet food truck industry -- by unveiling a food truck that serves marijuana-themed meals.

The company, called MagicalButter.com, acknowledges it's not quite ready for business. State law bars the consumption of marijuana in public, and cannabis businesses have to operate out of a fixed location with a physical address.

"The [state liquor control] board has been very, very strict on allowing anything that looks like a mobile dispensary," attorney Hilary Bricken told CBS station KIRO.

There have also been concerns, and greater regulatory scrutiny, about the potency of cannabis-infused foods. In Colorado, several deaths were recently linked to "edible" marijuana products sold in the state. Doctors in metro Denver also have reported a rise in the number of young children hospitalized for ingesting marijuana, mostly by accidentally eating cannabis-infused edibles that look like regular candies or cookies.

"If you leave it out on the counter, there's no way a child's going to know the difference," Dr. George Wang with Children's Hospital said in an interview with CBS station KCNC in Denver.

Bricken, meanwhile, says it might be years before a marijuana food truck could operate legally on the streets of Seattle. And the MagicalButter food truck, with its pot-infused peanut butter and jelly sandwiches?

"As of right now, we're only doing private service," says said company's Jeremy Cooper. "So for special events on private property."
