A colorful RV filled with marijuana candies and other edibles caught fire Sunday night en route to Philadelphia on Weed World Candies' East Coast college tour.

The vehicle fire stopped traffic on the Delaware Memorial Bridge between New Jersey and Delaware temporarily closed multiple lanes while firefighters from both states stopped the blaze.

Weed World Candies, established in 1999, drives painted RVs around the country every year in an attempt to promote the decriminalization and legalization of marijuana, said CED Dr. Dro. This RV – which was carrying about $50,000 in candies Sunday night – had just finished a stop at Howard University in Washington, D.C., and was headed to visit Temple University, Drexel University and the University of Pennsylvania, Dro said.

The entire RV was destroyed, resulting in a loss of about $120,000 for the company, he said. The truck was filled with about 19 varieties of lollipops, as well as marijuana-laced rice crispy treats, brownies, ice cream and popcorn.

Dro said the company uses hemp-based products in cities where marijuana is not legalized.

"We're just trying to get the message out without going to jail," Dro said. "People love us."

No one on the Weed World Candies RV was injured in the fire, which broke out shortly before 7 p.m. The Delaware River and Bay Authority notified travelers of the fire and subsequent lane closures via Twitter Sunday night.

The company uses the RVs because they're a "bigger billboard" than driving a regular vehicle, Dro said. They also allow about five or six people to travel together comfortably, especially when on the annual college tours.

Initially, all northbound lanes on the bridge were closed, but shortly after, the bridge re-opened two lanes for drivers to pass.

It's unclear what caused the fire. Passing motorists captured the blaze on video.

Firefighters from the Holloway Terrace, Goodwill and Minquadale fire companies in Delaware and the Deepwater Fire Company in New Jersey responded to the blaze, according to the authority.

College students shouldn't worry though, Dro said. Another RV is set to hit the road Wednesday and continue the remaining stops on the East Coast tour between Philadelphia and Boston. An updated itinerary will be released on Facebook as soon as it's finalized, he said.
