An RV carrying marijuana-laced candy caught fire on the main bridge connecting Delaware and New Jersey, losing $50,000 worth of product, according to the truck’s owner and authorities.

The incident happened Sunday and caused traffic delays as part of the Delaware Memorial Bridge was closed for several hours.

NBC10 was among the first to report on the incident.

Officials said the “Weed World Candies” vehicle was a “bus-style RV” and it was headed from the District to Philadelphia around 6 p.m. Sunday on the north side of the bridge when it caught fire. Some lanes of the bridge were closed for several hours as fire crews responded to the incident. No one was injured, according to officials at the Delaware River and Bay Authority, which oversees the bridge.

Delaware authorities said four people were on the vehicle at the time and the exact cause of the fire is under investigation.

NBC10 said Weed World Candies was started in 1999 and uses tour vehicles to push for the decriminalization and legalization of marijuana. It also sells marijuana-laced candy.

According to an NBC10, the owner of Weed World Candies — who is known as Dr. Dro — roughly $50,000 worth of merchandise was destroyed in the fire. NBC10 said the company is visiting colleges on the East Coast.
